VICP Registry Case Source Bundle Canonical URL: https://vicp-registry.org/case/USCOURTS-cofc-1_18-vv-00056 Package ID: USCOURTS-cofc-1_18-vv-00056 Petitioner: Hayley Stricker Filed: 2018-01-11 Decided: 2024-01-02 Vaccine: HPV Vaccination date: 2015-09-29 Condition: systemic lupus erythematosus Outcome: denied Award amount USD: AI-assisted case summary: Hayley Stricker, born in 1993, received the first dose of the HPV vaccine on September 29, 2015. She alleged that this vaccine caused her to develop systemic lupus erythematosus (SLE). Her mother has multiple sclerosis, a condition that could increase susceptibility to autoimmune diseases. Before vaccination, Ms. Stricker had acne treated with minocycline and doxycycline, and she had contracted the human papillomavirus (HPV). Approximately one month after vaccination, around November 1, 2015, she began experiencing symptoms such as joint pain, rash, and fatigue, which interfered with her dental hygienist training. She was diagnosed with a connective tissue disease in December 2015, and this diagnosis was later changed to SLE in December 2018 after a blood test revealed a double-stranded DNA antibody. Ms. Stricker's claim was based on the theory of molecular mimicry, arguing that the HPV vaccine's components resembled human tissue, triggering an autoimmune response. The respondent argued that Ms. Stricker's SLE was either drug-induced from her acne medication or spontaneously occurring. The Special Master denied compensation, finding that Ms. Stricker failed to prove by a preponderance of the evidence that the HPV vaccine caused her SLE. The Special Master reviewed numerous epidemiologic studies, most of which did not show an increased incidence of SLE following HPV vaccination. The studies that did suggest a link were found to be unreliable due to flawed methodology or questionable authors. The Special Master also found the theory of molecular mimicry unpersuasive, as Ms. Stricker did not provide sufficient evidence to establish a causal link between the vaccine and SLE. Furthermore, the Special Master considered alternative causes, finding that tetracycline use was a more likely explanation for her condition than the vaccine, although not definitively proven. The court affirmed the Special Master's decision, finding no legal errors and that the Special Master appropriately weighed the evidence and expert testimony.

PUBLISHED DECISION DENYING COMPENSATION1 Hayley Stricker alleges a human papillomavirus vaccine caused her to suffer systemic lupus erythematous (“SLE”). She retained a rheumatologist, Thomas Zizic, to support her claim. The Secretary denied she was entitled to compensation and presented opinions from two people---a rheumatologist, Carlos Rose, and an immunologist, James Moy. Ms. Stricker, her mother, a friend, a teacher, and these doctors testified at a hearing. 1 Because this Decision contains a reasoned explanation for the action taken in this case, it must be made publicly accessible and will be posted on the United States Court of Federal Claims’ website, and/or at https://www.govinfo.gov/app/collection/uscourts/national/cofc, in accordance with the E-Government Act of 2002. 44 U.S.C. § 3501 note (2018) (Federal Management and Promotion of Electronic Government Services). This means the Decision will be available to anyone with access to the internet. In accordance with Vaccine Rule 18(b), the parties have 14 days to identify and move to redact medical or other information, the disclosure of which would constitute an unwarranted invasion of privacy. Any changes will appear in the document posted on the website. Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 2 of 48 Ms. Stricker has not demonstrated that she is entitled to compensation. The primary obstacle is that she has not supported Dr. Zizic’s opinion that an HPV vaccine can cause SLE. Multiple reliable epidemiologic studies have searched for an increased incidence of SLE after HPV vaccination and failed to detect an increase. This epidemiologic evidence undermines Ms. Stricker’s claim. Ms. Stricker has not otherwise presented theories with sufficient evidentiary value to carry her burden. Thus, she is not entitled to compensation. A full discussion follows. I. Events in Ms. Stricker’s Life Ms. Stricker’s life is organized in four periods, followed by a summary. A. Early Life through Vaccination Ms. Stricker’s mother is Jennifer Stricker, and Jennifer’s Stricker’s health contributes to Ms. Stricker’s claim that the HPV vaccination caused her to suffer SLE. Jennifer Stricker was born in 1963. Tr. 50. She gave birth to Hayley in 1993. By 2015, Jennifer Stricker was diagnosed with multiple sclerosis. Tr. 53; see also Exhibit 14 at 2 (noting a family history of multiple sclerosis). Multiple sclerosis is considered an autoimmune disease, meaning doctors understand that the body’s immune system attacks the central nervous system. Tr. 325; see also W.C. v. Sec’y of Health & Hum. Servs., 704 F.3d 1352, 1354 (Fed. Cir. 2013) (defining multiple sclerosis). Ms. Stricker’s multiple sclerosis appears particularly severe as the disease prevented her from working in her career as a dental hygienist and prevents her from driving. Tr. 27, 53. Dr. Zizic opined that Jennifer Stricker’s multiple sclerosis placed Hayley Stricker at greater risk for developing an autoimmune disease, such as SLE. Tr. 203. Dr. Rose elaborated on this point with more sophistication. According to Dr. Rose, if multiple sclerosis is associated with certain genes, if Jennifer Stricker has those specific genes, if SLE is associated with certain genes, if the genes associated with multiple sclerosis match the genes associated with SLE, and if Jennifer Stricker passed on those genes to her daughter, then Hayley Stricker could have an increased genetic susceptibility to developing SLE. Tr. 589-90, 627. In any event, Hayley Stricker’s health was mostly typical for her first two decades. In high school, Ms. Striker ran cross-country and participated in other 2 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 3 of 48 sports. Tr. 21, 65, 77. She began practicing yoga and worked at the front desk of a yoga studio. Tr. 21-22, 77. When in high school, Ms. Stricker developed acne, for which she saw a dermatologist, Thomas Breza. Tr. 113. In 2010, Dr. Breza prescribed a medication for acne, minocycline, that she took for several years. Tr. 97. Ms. Stricker’s use of minocycline is a foundation for Dr. Rose’s theory that Ms. Stricker developed drug-induced lupus. Tr. 529, 607, 612.2 After high school, Ms. Stricker attended Florida Atlantic University for basic credits. Tr. 78. She continued to practice yoga and became certified as a yoga instructor in 2014. Exhibit 1 (affidavit) ¶ 3, Tr. 22, 66, 78-79. From Florida Atlantic University, Ms. Stricker applied for a dental hygienist program at Broward County College. Tr. 78-80. Ms. Stricker was interested in becoming a dental hygienist because she had watched her mother work when she was younger and liked the work and environment. Tr. 135. She was one of 16 applicants accepted into the program. Tr. 332. The dental hygienist program required an annual physical exam. Tr. 84. Thus, Ms. Stricker saw her primary care physician, Janet Robinson, on July 27, 2015. Exhibit 14 at 8; Tr. 84. Dr. Robinson recorded that Ms. Stricker has a “very healthy diet and exercises.” Exhibit 14 at 8; accord Tr. 83, 86. The record documents that Ms. Stricker has no fatigue. Exhibit 14 at 9; Tr. 86. Ms. Stricker’s skin was assessed as normal. Dr. Robinson did not see any joint swelling. Exhibit 14 at 9; Tr. 87. Dr. Robinson ordered routine blood work. Tr. 87. The results were normal. Exhibit 14 at 61. The testifying experts generally agreed that the blood tests were normal. Tr. 216-18, 243-44, 624. Based on the normal blood test results in July 2015, Dr. Zizic reasoned that (a) the agent inciting her SLE must have been encountered after July 2015, or (b) Ms. Stricker had antibodies that were not detected in this testing. Tr. 350. Dr. Rose responded to this last point by noting that Dr. Robinson did not order a test for a common marker for autoimmune diseases, an anti-nuclear antibody test. Tr. 2 Minocycline is a type of tetracycline. Another type of tetracycline is doxycycline. See Dorland’s at 1876 (defining tetracycline). Because Ms. Stricker eventually was prescribed doxycycline, the parties and their experts sometimes refer to Ms. Stricker’s use of tetracyclines. 3 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 4 of 48 628. Thus, the lack of testing means she could have had antibodies, making minocycline a potential cause. Tr. 629. On August 11, 2015, Ms. Stricker saw her dermatologist, Dr. Breza, because of acne on her face. At this appointment, Dr. Breza changed her medication from minocycline to doxycycline hyclate 100 mg. Exhibit 11 at 6, Exhibit 74 (affidavit) ¶ 1, Tr. 97. Ms. Stricker sought a second opinion from a different dermatologist, Dr. Green. Exhibit 8 at 5 (Aug. 21, 2015); Exhibit 74 (affidavit) ¶ 1. Dr. Green changed the doxycline hyclate to Acticlate 150mg. Id.; see also Pet’r’s Br., filed May 13, 2022, at 4-5, Resp’t’s Br., filed July 12, 2022, at 12. Around the same dates she was seeing the dermatologist, Ms. Stricker also saw her gynecologist, Dr. Bernstein, in a return appointment. Exhibit 7 at 83 (August 11, 2015). During this appointment, Ms. Stricker had her first Pap smear. Tr. 88. The Pap smear is a test to detect, among other problems, infections with human papillomavirus and cervical cancer. Dorland’s at 1866. Ms. Stricker’s Pap smear detected that she was infected with a strain of the human papillomavirus. Exhibit 7 at 116. The detection of this infection provides little information about when she first developed the infection. Tr. 604, 680; see also Tr. 242-43. Ms. Stricker most recently could have contracted a sexually transmitted disease, such as an HPV infection, in 2014. Exhibit 7 at 83 (“Last partner – 2014”), Tr. 88-89, 124. Infections with human papillomaviruses can cause SLE. Tr. 169 (Dr. Zizic), 602 (Dr. Rose). Whether the latency between the infection of SLE and the first manifestation of SLE is appropriate is a point of disagreement among the experts. Tr. 604, 681. A long latency might be appropriate because the virus can lie dormant and replicate years later. Tr. 604-06, 680-81. Although, as revealed by the Pap smear, Ms. Stricker was infected with one strain of the human papillomavirus by August 11, 2015, the vaccine could protect her against other strains. Tr. 23-24, 90. Thus, Ms. Stricker scheduled a return visit. In the September 29, 2015 appointment with Dr. Bernstein, Ms. Stricker received a dose of the human papillomavirus vaccine. Exhibit 6 at 2; Tr. 24, 82. She did not receive any other vaccines that day. Tr. 91. Ms. Stricker alleges this HPV vaccination caused her to develop SLE. B. Vaccination through One Year Later In the first weeks after the vaccination, Ms. Stricker appeared to be fine. She was attending school to be a dental hygienist. Tr. 24; see also Tr. 166 (Dr. 4 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 5 of 48 Zizic indicating that Ms. Stricker began having symptoms of SLE about six weeks after the vaccination). Ms. Stricker returned to her dermatologist, Dr. Green, on October 21, 2015. Exhibit 8 at 3. The prescription for Acticlate was continued. Id. Approximately one month after the September 29, 2015 vaccination, Ms. Stricker began to have health problems that interfered with her usual activities. See Exhibit 1 ¶ 5, Tr. 24 (Jennifer Stricker’s testimony that Hayley’s knees and ankle hurt), 66 (Ms. Stricker’s testimony that one month after vaccination, Ms. Stricker could not get out of bed), 91-93 (testimony that she was fatigued in early November 2015), 338 (testimony of a school instructor that Ms. Stricker informed her that her hands hurt, possibly in October 2015). By mid-November, Ms. Stricker was having more troubles in her musculoskeletal system. She was using medical tape to stabilize her wrists as she tried to perform varies techniques in her dental hygienist program. Tr. 25-27, 94. She was having numbness in her fingers. Tr. 27, 92. She stopped her yoga workouts. Tr. 26, 95. In the middle of November, Ms. Stricker searched the internet for possible causes of her symptoms. Based upon the information she found, Ms. Stricker stopped taking doxycycline. Exhibit 15 at 9 (Dr. Saba’s Dec. 29, 2015 report indicating that Ms. Stricker stopped taking doxycycline around Thanksgiving); Tr. 31, 98-99, 101, 113. Once she stopped, she did not resume taking doxycycline. Tr. 98. By Thanksgiving, Ms. Stricker was in so much pain that she begged her mother to schedule an appointment with Dr. Robinson. Jennifer Stricker did so, but the earliest appointment was on December 4, 2015. Tr. 28-29, 95-96. Before Ms. Stricker’s appointment with Dr. Robinson, Ms. Stricker was scheduled for a return appointment with her gynecologist to receive the second dose of the HPV vaccine. Exhibit 2 ¶ 9, Tr. 29. However, Jennifer Stricker had a “gut feeling” that the September 29, 2015 HPV vaccine caused the decline in her daughter’s health. Thus, Jennifer Stricker canceled this appointment. Id. Hayley Stricker has not received a second dose of the HPV vaccine. The appointment with Dr. Robinson took place, as scheduled, on December 4, 2015. In the history, Dr. Robinson memorialized Ms. Stricker’s complaint that her joint pain and a rash started three weeks ago. Exhibit 14 at 1. The Secretary noted that if “three weeks” were exactly 21 days, then the problems would have 5 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 6 of 48 started on November 13, 2015 (or 46 days after the vaccination). Resp’t’s Br. at 12. However, ample and persuasive evidence places the onset of Ms. Stricker’s symptoms of SLE around November 1, 2015. Tr. 100. The testifying experts proposed November 1, 2015 as the beginning of Ms. Stricker’s lupus, regardless of whether the lupus was systemic lupus erythematosus or drug-induced lupus. Tr. 214 (Dr. Zizic), 219 (same), 470 (Dr. Rose). Dr. Rose further opined that the acute onset of Ms. Stricker’s symptoms reminded him of patients he has diagnosed as suffering from drug-induced lupus. Tr. 531-32. Dr. Robinson’s report also contains a discrepancy regarding Ms. Stricker’s use of doxycycline hyclate. Dr. Robinson’s history states: “[Ms. Stricker] has a long [history of] acne, currently on 150 mg of doxycycline hyclate from Dr. Green with control of her acne . . . back on doxy since August.” Exhibit 14 at 1. However, preponderant evidence, including Dr. Saba’s December 29, 2015 report and the testimony from Ms. Stricker, establishes that Ms. Stricker stopped her anti- acne medication before seeing Dr. Robinson. As to the problems for which Ms. Stricker scheduled the appointment with Dr. Robinson, Dr. Robinson’s history memorializes that Ms. Stricker received the HPV vaccine on September 29, 2015. Exhibit 14 at 1. Ms. Stricker complained of “sudden onset of constant episodes of moderate lower back, bilateral shoulder, bilateral hand, bilateral finger(s) and right knee arthralgias, described as aching, radiating to the bilateral foot.” Exhibit 14 at 1; see also Tr. 100. Upon examination, Dr. Robinson did not perceive any joint swelling. Id. at 3. Dr. Robinson assessed Ms. Stricker as having “Arthralgia of multiple sites.” Id. Dr. Robinson ordered a series of lab tests. Id.; see also Tr. 103. Jennifer Stricker and Ms. Stricker testified that they talked to Dr. Robinson about a potential role for the HPV vaccine. Tr. 31, 44, 102. As to the possible cause of the problems, Dr. Robinson wrote: “We are going to put the doxycycline on hold in case this is a hypersensitivity reaction. Could be related to her Gardasil vaccination but it has been over two months ago.” Exhibit 14 at 3. The laboratory returned the results on December 8, 2015. Exhibit 14 at 17- 20. Some results fell outside of the expected range. For example, Ms. Stricker had high levels of globulin, alkaline phosphatase, C-reactive protein, and erythrocyte sedimentation rate. Id. at 18; see also Tr. 222-23 (Dr. Zizic). 6 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 7 of 48 Dr. Robinson discussed these results with Jennifer Stricker and directed Ms. Stricker to bring the results to her next dermatology visit. Exhibit 14 at 17. Dr. Robinson also referred Ms. Stricker to a rheumatologist. Id. The dermatology appointment with Dr. Green occurred the next day, December 9, 2015. Exhibit 8 at 1. There is a note to “D/C [presumably “discontinue”] Acticlate 150 mg.” Id. In the circumstances of other health problems, Ms. Stricker was much less concerned about acne. Tr. 102. For Ms. Stricker’s training to become a dental hygienist, a significant test was scheduled for December 11, 2015. Exhibit 1 (affidavit of Hayley Stricker) ¶ 13. Ms. Stricker was responsible for bringing a person, who would act as a patient, and was expected to demonstrate techniques of a dental hygienist on this person. For this process, Ms. Stricker chose her mother. Tr. 34, 106-07, 342. Ms. Stricker could not move easily and experienced a great deal of pain. Tr. 35. While in the car going home, Ms. Stricker cried. Tr. 35. As a result of Ms. Stricker’s health problems, the family canceled a vacation trip to Disney. Exhibit 2 ¶ 17, Tr. 37. They also pursued an appointment with a rheumatologist more aggressively. Tr. 38. Ms. Stricker was able to schedule an appointment with a rheumatologist, Jihan Saba, on December 29, 2015. Exhibit 15 at 9.3 The history Dr. Saba recorded indicated that Ms. Stricker had taken minocycline for four years but switched to doxycycline in August. Id. Ms. Stricker also informed Dr. Saba that she had stopped taking doxycycline “shortly after her joint symptoms started.” Id. Dr. Saba was informed that Ms. Stricker received “the first dose of Gardasil vaccine just prior to the onset of her symptoms.” Id. Ms. Stricker’s symptoms included “sudden onset of joint pain and swelling . . . involving the small joints of the hands, elbows, shoulders, feet and right knee.” Id.; see also Tr. 39. Dr. Saba memorialized results from the laboratory studies from earlier that month. Exhibit 15 at 9. On examination, Dr. Saba detected swelling in various joints. Id. at 10. Based upon this information, Dr. Saba assessed Ms. Stricker as suffering from “connective tissue disease.” Exhibit 15 at 12. Dr. Saba stated that she informed Ms. Stricker and her mother that “the features of connective tissue 3 Dr. Zizic is familiar with Dr. Saba and invited her to join his practice. Dr. Saba declined because she moved out of the area. Tr. 234-35. Dr. Zizic did not speak to Dr. Saba about Ms. Stricker’s case. Tr. 284. 7 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 8 of 48 disease may frequently change over time with a diagnosis may need to be changed.” Id. Dr. Saba’s note indicates that this was part of a “long conversation.” Id. Jennifer Stricker testified that Ms. Stricker and she asked Dr. Saba about minocycline as a potential cause. Exhibit 2 ¶ 18, Tr. 39, 45; see also Tr. 136 (testimony of Ms. Stricker). According to Jennifer Stricker, Dr. Saba left the room, came back, and told them that minocycline could not have been the cause because the drug would have left Ms. Stricker’s body. Id. Dr. Saba’s record corroborates that they discussed “drug-induced lupus as a possibility.” Exhibit 15 at 12. Dr. Saba wrote that minocycline can cause drug-induced lupus but that Dr. Saba “could not find much information in the literature regarding doxycycline induced lupus.” Id. Jennifer Stricker also testified that Ms. Stricker and she asked about the HPV vaccine as a potential cause. Tr. 39; see also Tr. 110 (testimony of Ms. Stricker). According to Jennifer Stricker, Dr. Saba stated that the HPV vaccine could have been a trigger. Id. However, Dr. Saba’s December 29, 2015 medical record does not memorialize any discussion about the HPV vaccine. See Exhibit 15 at 9-12. Dr. Saba ordered an additional set of laboratory studies and prescribed a low dose of prednisone. Exhibit 15 at 12; see also Tr. 109. Dr. Saba recommended that after some additional testing, Ms. Stricker take hydroxychloroquine. Exhibit 15 at 12. The laboratory results contained some abnormal values. Id. at 67; see also Tr. 226-27. After Dr. Saba diagnosed Ms. Stricker as suffering from a connective tissue disease on December 29, 2015, the remaining medical records carry less value in determining whether the September 29, 2015 HPV vaccine caused her rheumatological problem. Thus, these additional records are presented more summarily. In January 2016, Ms. Stricker notified the government about her potential adverse reaction by submitting a form to the Vaccine Adverse Events Reporting Service. Exhibit 77.4 Ms. Stricker indicated that she received the vaccine on 4 Although Hayley Stricker is listed as the person completing the form, Jennifer Stricker stated she filled out the form for her daughter. Exhibit 77 at 3. The submitter of the form is not a fact material to outcome of this case. 8 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 9 of 48 October 29, 2015. Id. at 1 (box 10). However, Ms. Stricker actually received the vaccine on September 29, 2015. See Tr. 111-12. Dr. Saba determined that the lab results indicated that Ms. Stricker could start taking hydroxychloroquine. Exhibit 15 at 63 (Jan. 4, 2016); see also Tr. 109. The medications improved Ms. Stricker’s condition. Tr. 105. Ms. Stricker resumed her classes to become a dental hygienist. Tr. 41, 45. Ms. Stricker saw a second rheumatologist, Christine Savage, on February 23, 2016. Exhibit 17 at 43. The reason for the visit was Dr. Robinson’s referral. Id. Jennifer Stricker testified that the appointment was made much earlier. Tr. 43. Dr. Savage’s medical history is more-or-less consistent with the above recitation of events. For example, Dr. Savage indicates that Ms. Stricker “correlates that her symptoms started a few months after switching her acne medication from minocycline to doxycycline, and receiving a [Gardasil] injection.” Exhibit 17 at 43. Dr. Savage recounted that Ms. Stricker was taking prednisone and Plaquenil. Together, “the combination of prednisone and Plaquenil has resolved 90% of her joint pain symptoms.” Id. at 44. In her assessment, Dr. Savage included different conditions, including “CTD [connective tissue disease].” Id. at 46; accord Tr. 43. According to Jennifer Stricker, Dr. Savage stated that neither minocycline nor doxycycline would have caused Ms. Stricker’s condition. Tr. 44. Jennifer Stricker also testified that Dr. Savage said the HPV vaccine was the trigger. Id.; Exhibit 1 (Ms. Stricker’s affidavit) ¶ 26. However, Jennifer Stricker acknowledged that Dr. Savage’s note does not say much about minocycline, doxycycline, or the HPV vaccine. Tr. 45; see also Exhibit 17 at 46. The February 23, 2016 appointment appears to be the only visit with Dr. Savage. Thereafter, Ms. Stricker continued to see Dr. Saba as her rheumatologist. Dr. Saba continued to see Ms. Stricker periodically. Exhibit 15, passim. During appointments, Dr. Saba adjusted medications. Tr. 116. By the end of February 2016, Dr. Saba was recommending a taper of prednisone. Exhibit 15 at 52; see also Tr. 125 (Ms. Stricker indicating she last took prednisone in May 2016). C. Lupus Diagnosis In December 2018, Ms. Stricker saw Dr. Robinson as part of an annual exam. Exhibit 33 at 1. In the review of systems, Dr. Robinson recorded that Ms. Stricker had “joint stiffness or swelling and cold extremities, but no joint pain, no weakness of muscles or joints.” Id. at 2. For the physical examination, Dr. 9 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 10 of 48 Robinson did not comment, either affirmatively or negatively, about Ms. Stricker’s joints. Id. at 3. Dr. Robinson ordered more laboratory studies. One of the lab tests revealed that Ms. Stricker had a double-stranded DNA antibody. Exhibit 31 at 1; see also Tr. 115. After learning this information and evaluating Ms. Stricker, Dr. Saba changed the diagnosis to systemic lupus erythematous. Exhibit 35 at 4; see also Tr. 45, 115, 166-68. Dr. Zizic explained that antibodies against double-stranded DNA are 99 percent specific for lupus. Tr. 240. Dr. Rose agreed that the diagnosis was most likely systemic lupus erythematosus. Tr. 529. However, Dr. Rose stated that even after the detection of anti-double stranded DNA antibodies, drug-induced lupus remains a potential diagnosis for Ms. Stricker. Tr. 529, 630. D. Currently5 Although Ms. Stricker graduated from the program to become a dental hygienist and worked for a time as a dental hygienist, she found she could not perform the duties. Tr. 118. Instead, Ms. Stricker works for a yoga studio where she directs teachers of yoga. Tr. 48, 55, 121, 141. In recent medical records from Dr. Saba, Ms. Stricker denied having a list of problems including “joint pain, joint swelling, morning stiffness, rashes, photosensitivity.” Exhibit 92 at 2 (Aug. 17, 2021); accord Exhibit 87 at 9 (Feb. 16, 2021), Exhibit 87 at 1 (Aug. 13, 2020). When these records were pointed out to Ms. Stricker on cross-examination, she stated that she is frustrated with Dr. Saba. To Ms. Stricker, Dr. Saba asks questions like an “auctioneer” and does not write down information that Ms. Stricker conveys to her. Tr. 128-31; see also Tr. 149 (redirect examination). Ms. Stricker has considered changing rheumatologists; however, she ultimately decided to continue with Dr. Saba, as she knows Ms. Stricker’s history. Tr. 134. Dr. Saba has continued to prescribe hydroxychloroquine, and while on this medication, Ms. Stricker has not experienced new symptoms. Tr. 116, 147-48. Dr. Rose opined that Ms. Stricker’s disease is “mild,” potentially controlled with the hydroxychloroquine. Tr. 470. Dr. Rose further opined that the use of medication interferes with determining whether Ms. Stricker’s lupus is “active” right now. Tr. 539, 763. If Ms. Stricker were his patient, Dr. Rose might consider carefully and slowly tapering the hydroxychloroquine. Tr. 540-41, 615, 620. 5 The witnesses testified in January 2022. 10 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 11 of 48 E. Summary A few events in Ms. Stricker’s life are key to understanding the positions of the parties and the experts they have retained. Ms. Stricker’s mother suffers from an autoimmune disease, which might increase Ms. Stricker’s susceptibility to developing an autoimmune disease. Before the vaccination, Ms. Stricker was exposed to various substances associated with lupus. These include the medications for acne, minocycline and doxycycline. Before the vaccination, Ms. Stricker also became infected with the human papillomavirus, although the date of infection was more than one year before the vaccination. Ms. Stricker received the first dose of the HPV vaccine on September 29, 2015. She developed symptoms of lupus around November 1, 2015. The symptoms, such as joint pain, progressed, and Ms. Stricker was diagnosed with a connective tissue disease. Approximately two years later, Ms. Stricker’s diagnosis was changed to systemic lupus erythematosus. Ms. Stricker alleges that the HPV vaccine caused her to develop SLE. The prominent events regarding her claim are discussed next. II. Procedural History Ms. Stricker began this litigation by filing her petition on January 11, 2018. With her petition, Ms. Stricker submitted affidavits from herself and from her mother. Exhibits 1-2. She periodically filed medical records. Within a month of filing the petition, Ms. Stricker submitted letters from doctors who treated her. Exhibits 22-25. The rheumatologist, Dr. Saba, stated that Ms. Stricker’s mother “asked me to give my opinion on whether her connective tissue disease may have been triggered by the [Gardasil] vaccine since she would like to pursue with the vaccine injury program.” Exhibit 22 (dated Jan. 31, 2018). Dr. Saba’s response was indeterminant: It is known that connective tissue disease[s] have both an underlying genetic component and an environmental trigger which can be an infection, environmental pollutants, smoking, vaccines, psychological distress etc. Because of the chronological timing of the vaccine vis-à- vis the onset of her symptoms it is very possible that it was the environmental trigger in her case. Id. 11 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 12 of 48 The letter from Ms. Stricker’s primary care physician, Dr. Robinson, spoke more supportively of the claim. Dr. Robinson wrote that Ms. Stricker “received her first Gardasil vaccination on 9/29/15 and her symptoms started around mid November of 2015 so it does seem likely that her autoimmune disease was trigger[ed] by the vaccine.” Exhibit 23 (dated Jan. 9, 2018). A third treating doctor, the dermatologist (Dr. Breza), also wrote a letter on Ms. Stricker’s behalf. Dr. Breza explained that when patients with minocycline- induced lupus stop taking the medication, “the symptoms and blood serologies resolve.” Exhibit 24 at 1. For support, Dr. Breza submitted the article by Lawson and others. Dr. Breza also commented that Ms. Stricker’s symptoms “have not resolved several years after discontinuation of minocycline.” Id. Thus, Dr. Breza “can be certain that minocycline was not the cause of her connective tissue disorder.” Id. After filing more medical records, Ms. Stricker supported her claim by filing a report from Dr. Zizic on February 14, 2019. Exhibit 37. Dr. Zizic stated that Ms. Stricker suffered from systemic lupus erythematosus, not “minocycline-induced systemic lupus erythematosus.” Id. at 42. For a theory to explain how an HPV vaccine can cause systemic lupus erythematosus, Dr. Zizic proposed molecular mimicry. Id. at 28, 34-39. Dr. Zizic also discussed granzyme B. Id. at 30. However, this presentation was not clear and in a March 12, 2019 status conference, Ms. Stricker clarified that her theory was molecular mimicry. The Secretary responded to Dr. Zizic’s report by obtaining a report from Dr. Moy. Exhibit A (filed June 14, 2019). The Secretary added a report from Dr. Rose on September 13, 2019. Exhibit L. Dr. Moy agreed that Ms. Stricker suffers from SLE. Exhibit A at 6. Dr. Moy stated that the HPV vaccination did not cause Ms. Stricker’s SLE. In support, Dr. Moy generally relied upon epidemiologic studies. Id. at 5. Dr. Moy appeared to indicate that Ms. Stricker’s HPV infection, which she developed before the vaccination, could have caused her SLE. Id. at 6. Dr. Moy did not raise any challenges to molecular mimicry. See Exhibit A. Dr. Rose questioned whether Ms. Stricker suffered from SLE or from drug- induced lupus. Exhibit L at 9-11. Citing various epidemiologic studies, Dr. Rose questioned whether an HPV vaccine can cause systemic lupus erythematosus. Id. at 13-18. Dr. Rose proposed that Ms. Stricker might have drug-induced lupus. Alternatively, Dr. Rose proposed that Ms. Stricker’s SLE occurred spontaneously. Id. at 19, 22. 12 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 13 of 48 Dr. Zizic addressed the opinions of Dr. Moy and Dr. Rose in a report filed on January 3, 2020. Exhibit 75. Dr. Zizic disagreed with Dr. Rose’s suggestion that Ms. Stricker could have drug-induced lupus. Id. at 1. Dr. Zizic also disputed Dr. Moy’s suggestion that an HPV infection caused Ms. Stricker’s SLE. Id. at 10. Finally, Dr. Zizic challenged the epidemiologic studies on which the Secretary’s experts had relied. Id. at 2-9. In the January 20, 2020 status conference, the parties were asked whether they wanted to retain epidemiologists. However, the parties demurred. Thus, Dr. Zizic’s report completed the stage in which experts disclosed their opinions. The parties were directed to submit additional material in advance of a potential adjudication. Order, issued Jan. 9, 2020. Ms. Stricker filed her brief and other materials on or before March 31, 2020.6 The Secretary submitted his materials on June 22, 2020. Ms. Stricker filed a reply on July 22, 2020. The undersigned determined that a hearing to receive oral testimony was appropriate. Order, issued Feb. 19, 2021. The parties determined that mutually convenient dates for the hearing was January 18, 2022 to January 21, 2022. The hearing proceeded as scheduled. Ms. Stricker, Jennifer Stricker, a friend, and a teacher from Ms. Stricker’s dental hygienist program testified about Ms. Stricker’s health and activities. Dr. Zizic testified on behalf of Ms. Stricker, opining that the HPV vaccination caused Ms. Stricker to suffer SLE. Dr. Rose and Dr. Moy testified on behalf of the Secretary. During the hearing, the Secretary attempted to elicit testimony from Dr. Moy regarding molecular mimicry. However, Ms. Stricker objected on the ground that Dr. Moy did not disclose any opinions regarding molecular mimicry in his reports. Tr. 652. This objection was sustained, and a portion of Dr. Moy’s testimony was struck. Tr. 666. Following the hearing, the parties submitted briefs responding to questions. See Pet’r’s Posthear’g Br., filed May 13, 2022; Resp’t’s Posthear’g Br., filed July 12, 2022; Pet’r’s Posthear’g Reply, filed Aug. 11, 2022. Ms. Stricker later 6 During the briefing stage, Ms. Stricker was awarded attorneys’ fees and costs on an interim basis. First Fees Decision, 2020 WL 1028901, issued Feb. 6, 2020. After the hearing, Ms. Stricker was given a second interim award of attorneys’ fees. Second Fees Decision, 2022 WL 2387994, issued Nov. 4, 2022. Her request for costs was deferred. Id. at *4. 13 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 14 of 48 submitted a notice of additional authority to which the Secretary responded. These submissions make the case ready for adjudication. III. Standards for Adjudication A petitioner is required to establish his case by a preponderance of the evidence. 42 U.S.C. § 300aa–13(1)(a). The preponderance of the evidence standard requires a “trier of fact to believe that the existence of a fact is more probable than its nonexistence before [he] may find in favor of the party who has the burden to persuade the judge of the fact’s existence.” Moberly v. Sec’y of Health & Hum. Servs., 592 F.3d 1315, 1322 n.2 (Fed. Cir. 2010) (citations omitted). Proof of medical certainty is not required. Bunting v. Sec’y of Health & Hum. Servs., 931 F.2d 867, 873 (Fed. Cir. 1991). Distinguishing between “preponderant evidence” and “medical certainty” is important because a special master should not impose an evidentiary burden that is too high. Andreu v. Sec’y of Health & Hum. Servs., 569 F.3d 1367, 1379-80 (Fed. Cir. 2009) (reversing special master’s decision that petitioners were not entitled to compensation); see also Lampe v. Sec’y of Health & Hum. Servs., 219 F.3d 1357 (Fed. Cir. 2000); Hodges v. Sec’y of Health & Hum. Servs., 9 F.3d 958, 961 (Fed. Cir. 1993) (disagreeing with dissenting judge’s contention that the special master confused preponderance of the evidence with medical certainty). When pursuing an off-Table injury, a petitioner bears a burden “to show by preponderant evidence that the vaccination brought about [the vaccinee’s] injury by providing: (1) a medical theory causally connecting the vaccination and the injury; (2) a logical sequence of cause and effect showing that the vaccination was the reason for the injury; and (3) a showing of a proximate temporal relationship between vaccination and injury.” Althen v. Sec’y of Health & Hum. Servs., 418 F.3d 1274, 1278 (Fed. Cir. 2005). IV. Althen Prong 1 To meet her burden regarding the first Althen prong, Ms. Stricker advances the opinions of Dr. Zizic and the articles on which he relies. Pet’r’s Posthear’g Br. at 28-57. Ms. Stricker offers the theory of molecular mimicry, although she may, as discussed below, have added a second theory involving granzyme B. The Secretary, on the other hand, challenges Ms. Stricker’s evidence by putting forward opinions from Dr. Moy and Dr. Rose as well as the articles on which they rely. Resp’t’s Posthear’g Br. at 7-20. 14 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 15 of 48 The parties offer various types of articles, which could be relevant to any causal theory. Thus, epidemiological studies, studies on the effects of vaccination, and case reports are discussed first in Sections IV.A through IV.C below. After those sets of foundational materials are examined, the two theories are analyzed in Section IV.D. A. Epidemiologic Studies7 For a lengthy discussion of the value of epidemiologic studies in the Vaccine Program, see Tullio v. Sec’y of Health & Hum. Servs., No. 15-51V, 2019 WL 7580149, at *5-8 (Fed. Cl. Spec. Mstr. Dec. 19, 2019), mot. for rev. denied, 149 Fed. Cl. 448, 475 (2020). Here, the parties have introduced multiple epidemiologic studies. They are presented in chronological order, beginning with the study that was published earliest. 1. Chao After the Food and Drug Administration licensed Gardasil, Merck undertook a safety study. Chao at 194, Tr. 416. Researchers, including some employees at Merck Research Laboratory, studied women in two managed-care organizations, Kaiser Permanente Southern California, and Kaiser Permanente Northern California. Chao at 194. Merck “had significant input into the study design and analytic plan, all pre-specified in a protocol that was approved by FDA.” Chao at 202, Tr. 362-64. Merck also “took part in the review of analysis and drafting and revising the manuscript.” Chao at 202, accord Tr. 560. However, “Kaiser Permanente authors held final decision power about all editorial suggestions.” Chao at 202. Using databases, the researchers identified 189,629 women who received an HPV vaccination. Practically all the women were ages 9-26 years old. Chao at 194. These women were followed for 180 days after receiving a vaccination. Id. Dr. Zizic and Dr. Rose disputed whether 180 days was sufficiently long. Tr. 373, 417, 430-32, 794. Within the vaccinated cohort, researchers looked for potential new autoimmune diseases, including systemic lupus erythematosus. Chao at 194. “The method for case identification was designed to be highly sensitive to capture any potential cases, to address potential undercoding or miscoding in the early course 7 Bibliographic information for articles cited in this decision is found in the appendix. 15 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 16 of 48 of an autoimmune condition.” Researchers consulted ICD-9 codes, abnormal lab values, and pharmacy prescription records. Chao at 195, Tr. 419- 21. Investigators removed any women who had been enrolled in the managed- care organization for less than 12 months. Chao at 195. Investigators also removed anyone with pre-existing autoimmune diseases. Id. Then, a case review committee (“CRC”) looked at the medical records. “The rheumatology CRC consisted of one paediatric and two adult rheumatologists.” Id. The CRC evaluated the diagnosis and determined the date of the onset. Id., Tr. 574. For cases involving SLE and four other conditions, researchers reviewed only a sample of potential cases. Chao at 195. The CRC members were masked to the person’s date of vaccination. Id. Tr. 424, 729. The authors presented this process in Table 1. Tr. 371, 375, 566-67. The above process (detecting autoimmune diseases among the vaccinated population) seems relatively uncontroversial. The controversial part of Chao concerns how researchers estimated the background (or incidence) of autoimmune diseases in the unvaccinated. Unvaccinated people began accruing time in the study either when they were members of the managed-care organization for twelve months or in August 2006, which is when the study began. Chao at 195. The accrual of a person’s time ended on the later of (1) the date of disenrollment, (2) the date of their first vaccination, or (3) the end of September 2008. Chao at 195. As Dr. Rose said, an unvaccinated person became a vaccinated person, meaning the unvaccinated and vaccinated groups comprised the same people. Tr. 422, 633, 636-37, 728. To identify potential new-onset autoimmune conditions in the unvaccinated population, the investigators used “the same identifying algorithm.” Chao at 195. This process identified some potential new onset cases among the unvaccinated people. However, researchers did not review medical records of unvaccinated people. Id. Instead, “Rubin’s multiple imputation was used to estimate the rates of new-onset autoimmune conditions by treating the actual status of new onset as missing data for the un-reviewed potential cases.” Id. The two steps of not reviewing medical records and using Rubin’s multiple imputation generated a large amount of testimony from Dr. Zizic and Dr. Rose. Dr. Zizic and Dr. Rose agreed that although Rubin’s imputation might be used when data is missing, the data was not missing. The researchers could have 16 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 17 of 48 accessed the medical records of the non-vaccinated people. Tr. 368-69, 372, 376, 416, 424-27, 568-69.8 Having determined the incidence of SLE in vaccinated people and having estimated the incidence of SLE in unvaccinated people, the researchers compared the rates. The researchers conducted a main comparison and two sensitivity analyses. Tr. 428. The results are presented in Table 3. Chao at 199, Tr. 427. The incident rate ratio (“IRR”) was relatively close to 1.0 for all three situations (1.07, 1.26, and 1.10).9 These rates and other data led the researchers to conclude: “There was no clear evidence of safety signal for autoimmune conditions following vaccination with HPV4 in this study.” Chao at 201. In doing so, the researchers recognized three limitations: (1) a potential complication for determining the onset of a disease, (2) many autoimmune diseases involved small numbers of cases, limiting the study’s power, and (3) the multiple imputation method was not a standard method for estimating background incidence rates. Id. at 201-02, accord Tr. 731. Dr. Zizic criticized the methodology in a few respects. First, he did not agree with limiting the risk period to 180 days. His point that some autoimmune diseases such as lupus could take longer than six months to recognize is a fair one. However, the researchers attempted to design a study to account for any potential delay in diagnosis. Moreover, Dr. Zizic has not presented any opinion to explain why any delay in diagnosis would skew the results. It would seem that because the researchers used the same algorithm to find autoimmune diseases in the vaccinated and unvaccinated groups, any flaw would not make a difference. Second, Dr. Zizic criticized the researchers for using Rubin’s imputation. This criticism has some validity as the researchers acknowledged if “the true new- onset confirmation rate was lower in the unvaccinated population, this may have biased the IRR estimates.” Chao at 202. But, again, Dr. Zizic fails to show why this unusual methodology skewed the results. In this regard, Dr. Zizic had a challenging task because some of the work of Chao and colleagues appears 8 Dr. Rose speculated that researchers did not have sufficient staffing to review all charts of unvaccinated people. Tr. 427, 568. Dr. Zizic considered a lack of resources to be “absurd.” Tr. 732. 9 An incidence rate ratio above 1.0 suggests that an agent may have caused a disease. See In re Viagra Products Liability Litigation, 572 F.Supp.2d 1071, 1078 (D. Minn. 2008). 17 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 18 of 48 undisclosed. Dr. Zizic challenges the way the researchers determined an estimated number of cases in the unvaccinated, reflected in Table 3 as 58 cases or an incidence of 10.3 per 100,000 person-years. Tr. 376, 733. In Dr. Zizic’s view, because the case review committee confirmed systemic lupus erythematosus in only one-third of the potential cases, then the incidence rate should be one-third lowered in the unvaccinated group. Dr. Zizic’s criticism is unpersuasive. First, how the researchers determined the estimated number of cases is not well-explained. Dr. Zizic seems to assume that the 58 cases correspond to data presented in column C of Table 1, a spot at which the CRC confirmed the diagnosis. However, it seems more likely that the Rubin’s method was substituted for the CRC review, meaning 58 cases actually corresponds to column E in Table 1. The researchers did not provide how many cases the computer algorithm identified before the researchers used Rubin’s method. But, strictly mathematically, if the computer algorithm had identified 174 potential onset cases, then the reduction from potential cases to confirmed cases would have been proportional. In short, although Dr. Zizic answered a leading question from Ms. Stricker’s counsel with an assent that he believed the Chao researchers “messed with” the background rates, Dr. Zizic has not shown this persuasively. Cf. J.C. Equipment Corp. v. England, 360 F.3d 1311, 1315 (Fed. Cir. 2004) (noting that expert testimony based upon leading questions can be rejected). 2. Arnheim-Dahlström Researchers from Denmark and Sweden investigated whether the qHPV vaccine increases rates of adverse events. Arnheim-Dahlström at 1. “Sweden and Denmark keep population based healthcare registers and thereby have unique opportunities to address the safety of HPV vaccination.” Id. at 2, accord Tr. 405. Researchers learned when young women received an HPV vaccine. Arnheim- Dahlström at 2. They also determined when each person experienced a “serious adverse outcome event,” defined as “records of inpatient admissions and hospital outpatient and emergency department visits.” Arnheim-Dahlström at 3, accord Tr. 407. 18 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 19 of 48 The way the researchers collected cases was attacked by Dr. Zizic. Tr. 382– 89. To Dr. Zizic, a focus on hospitalizations is not appropriate for SLE because less than 5% of patients with lupus are hospitalized. Tr. 383.10 Dr. Rose persuasively countered that pediatric rheumatologists in Europe see their patients in hospitals. Tr. 407, see also Arnheim-Dahlström at 5. Thus, the methodology in Arnheim-Dahlström is reliable. Arnheim-Dahlström and colleagues looked for serious adverse events within 180 days of vaccination. Arnheim-Dahlström at 3. “This period was chosen to allow for the insidious onset of the diseases studied and because diagnostic investigations may take time.” Id. The researchers determined how frequently SLE developed in unvaccinated and vaccinated people. Arnheim-Dahlström at 8 (Table 2). The adjusted rate ratio was 1.35 with a 95% confidence interval of 0.69- 2.67. Arnheim-Dahlström at 10 (Figure 2), accord Tr. 411. The researchers summarized: “the findings of this study, which were based on nearly one million girls and 700 000 vaccine doses, were reassuring for autoimmune . . . events after qHPV vaccination.” Arnheim-Dahlström at 4. 3. Geier In response to Dr. Rose’s cite to Chao, Arnheim-Dahlström, and other epidemiologic studies, Dr. Zizic presented a 2015 article by David A. Geier and Mark R. Geier. Exhibit 75 at 7.11 Geier and Geier undertook a study to evaluate “the potential for HPV4 vaccination to induce serious autoimmune events.” Geier at 1225. Geier and Geier used the VAERS database as their source of information. Geier at 1226, Tr. 289. They searched for specific diseases including SLE by computer code. Id. For controls, Geier and Geier used other reports from VAERS. Geier at 1226, Tr. 509. Geier and Geier determined the odds ratio for developing SLE after an HPV vaccination was 5.3. Geier at 1228 (Table 2). The experts took different views about the value of this article. In response to a leading question from Ms. Stricker’s attorney, Dr. Zizic indicated that there is nothing wrong from a methodological standpoint. Tr. 355. In contrast, Dr. Rose 10 Ms. Stricker has not advanced any argument against Arnheim-Dahlström in her posthearing brief. 11 Ms. Stricker submitted the Geier and Geier article as Exhibit 64. She later resubmitted it as Exhibit 95. 19 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 20 of 48 stated that this study is “absolutely not” reliable. Tr. 505. Dr. Rose stated “The definition of exposure is totally biased and bogus. The calculation of controls versus cases is ridiculous.” Tr. 509. Dr. Moy raised additional concerns. Tr. 671- 74. Ms. Stricker has not established the reliability of this Geier and Geier article. A primary flaw is using the VAERS database as a source. In multiple cases, special masters have rejected this methodology.12 See Tompkins v. Sec’y of Health & Hum. Servs., 117 Fed. Cl. 713, 721 (2014) (quoting special master’s decision describing the VAERS database as a “stocked pond”); Analla v. Sec’y of Health & Hum. Servs., 70 Fed. Cl. 552, 558 (2006) (noting that the Court has uniformly upheld concerns of special masters about VAERS reports); see also Doe v. Ortho-Clinical Diagnostics, Inc., 440 F.Supp.2d 465, 475-76 (M.D.N.C. 2006) (noting that Dr. Geier’s use of VAERS reports was not reliable). In their article, Geier and Geier attempted to vouch for their methodology by asserting the “VAERS Working Group of the CDC and the FDA have repeatedly analyzed and published epidemiologic studies based upon VAERS [6, 7].” Geier at 1226. Reference 7 is a 2002 article by the Geiers, which does not support a statement that the CDC used the VAERS database for an epidemiologic study. Tr. 508. In addition, Dr. Rose stated that the other reference by Singleton is not an epidemiologic study. Tr. 507.13 12 In a hearing before the Chief Special Master on October 22, 2021, Dr. Zizic was told that the Geiers are not trustworthy. See Chambers v. Sec’y of Health & Hum. Servs., No. 19-140V, 2022 WL 3369332, at *10 n.15 (Fed. Cl. July 22, 2022) (“the Geiers have repeatedly, and over a lengthy period of time, been deemed to be questionably-competent and scientifically-unreliable experts in the Vaccine Program—casting significant doubt on any studies they have authored.”). The Chambers hearing took place after the March 4, 2019 submission of Dr. Zizic’s report and the Geier article; however, Dr. Zizic still stated that Geier was “not a flawed study” in the January 2022 hearing in the instant case. Dr. Zizic was asked about the instruction in Chambers but did not recall the Chief Special Master telling him this. Tr. 288-89. Regardless of Dr. Zizic’s knowledge about the Geiers, the Geiers’ work is problematic. 13 Because Dr. Rose consulted and testified about Singleton, the better practice would have been to disclose this opinion and to file the Singleton article. However, in light of the consistent rejection of work by the Geiers, this oversight is harmless. 20 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 21 of 48 Furthermore, Geier and Geier have been repeatedly discredited in the Vaccine Program. See, e.g., America v. Sec'y of Health & Hum. Servs., No. 17- 542V, 2022 WL 278151, at *8 n.16 (Fed. Cl. Jan. 4, 2022) (“the authors of the Geier Article have been almost wholly discredited as experts in the Vaccine Program.”) (citing Hooker v. Sec'y of Health & Hum. Servs., No. 02-472V, 2017 WL 3033940, at *17 (Fed. Cl. Spec. Mstr. Apr. 11, 2017); King v. Sec'y of Health & Hum. Servs., No. 03-584V, 2011 WL 5926126, at *15 (Fed. Cl. Sept. 22, 2011) Doe/03 v. Sec'y of HHS, 2007 WL 2350645, at *3 (Fed. Cl. Spec. Mstr. July 31, 2007); and Daly v. Sec'y of HHS, No. 90–590V, 1991 WL 154573, at *7 (Cl. Ct. Spec. Mstr. July 26, 1991)). Thus, although the Geier article has been considered, it carries minimal weight. 4. Wang About one week before the hearing, Ms. Stricker submitted a 2017 article by Bin Wang and others.14 Dr. Zizic did not recall when he learned of the Wang article. Tr. 320. Wang and colleagues investigated whether vaccines increased the rate for developing SLE and rheumatoid arthritis. Wang at 756. The researchers’ methodology was to perform a meta-analysis. Tr. 180, 205.15 Wang and colleagues searched various databases for defined observational studies. Wang at 757. From a group of studies, the researchers selected some based upon various criteria, one of which was that the study’s “controls were those individuals without receiving vaccination.” Id. The authors also assessed the studies for quality (bias). Id. From the accepted studies, the authors extracted data and pooled them. Id., Tr. 205. The authors represented that the “present meta-analysis was performed by the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement.” Wang at 757. To Dr. Zizic, a study done in conformance with PRISMA’s methodology enhances its credibility. Tr. 207, 289.16 Nevertheless, Dr. Rose questioned the extent of peer review. The article indicates 14 Arguably, the submission of an article without an accompanying disclosure from an expert was not in accordance with the January 29, 2020 order for briefs. However, the Secretary did not object. 15 At line 5 of transcript page 180, “Lane” should be “Wang.” 16 The PRISMA website indicates “PRISMA may also be useful for critical appraisal of published systematic reviews, although it is not a quality assessment instrument to gauge the quality of a systematic review.” http://www.prisma- statement.org/. 21 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 22 of 48 that the journal that published the article, Autoimmunity Reviews, received a manuscript on April 19, 2017. Wang at 756. The article was accepted on April 23, 2017 and available online May 5, 2017. Id. Dr. Rose wondered how the peer- review could have worked in just four days. Tr. 497-98. Dr. Rose also asserted that the editors-in-chief of Autoimmunity Reviews are Dr. Shoenfeld and Dr. Gershwin, who have frequently testified that a vaccine injured someone. Id. Overall, the researchers identified five studies involving the HPV vaccine and SLE. Wang at 760 (Table 3), Tr. 287. These relevant five studies were by Verstraaten, Chao, Arnheim-Dahlström, Angelo, and Geier. Tr. 499; see also Wang at 759 (Table 1). The Geier study used in Wang was published in 2017 and is reference 48 in the Wang article. The 2017 Geier article is not an exhibit in this case. The 2015 Geier article, which is Exhibit 64 and Exhibit 95, is reference 60 in Wang. The Wang group excluded the 2015 Geier article because its data was “overlapping.” Wang at 758. Including the Geier study in the Wang meta-analysis is both questionable and significant. As discussed, the methodology of Geier and Geier is not reliable. Although Wang and colleagues assessed Geier and Geier as having high quality, Dr. Rose noted that Geier and Geier did not deserve a high ranking because they could not verify the outcome through the VAERS reports. Tr. 500. Including the 2017 Geier study affected the results in Wang. Tr. 290, 504. Of the five relevant studies, the Geier study found the highest relative risk. Wang at 760 (Figure 2) (highlighting added to identify studies involving the HPV vaccine). Geier is the only article in which the 95% confidence interval did not cross 1.0. See Id., Tr. 504. 22 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 23 of 48 Accordingly, the Wang article merits little, if any, weight. Cf. Moran v. Sec'y of Health & Hum. Servs., No. 16-538V, 2021 WL 4853544, at *29 (Fed. Cl. Spec. Mstr. Oct. 4, 2021) (giving less weight to the Wang study in the context of a claim that influenza vaccination caused rheumatoid arthritis). 5. Miranda Among the exhibits in this case, the next epidemiologic study chronologically was written by Sara Miranda and other researchers from France. This study was not included in the Wang meta-analysis. This group also used computer searches to determine whether the HPV vaccination was associated with various autoimmune diseases, including SLE. Miranda at 4761. In France, two nationwide databases linked by unique individual identifiers collect health information of the populace. In these databases, the researchers generally looked for any women aged 13-16 years from January 1, 2008 through December 31, 2012. Miranda at 4762. More than 2 million young women were followed for an average of 33 months. Miranda at 4763. The researchers attempted to find out when these people experienced 14 autoimmune 23 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 24 of 48 diseases including SLE. The researchers searched for ICD-10 codes, long-term reimbursement records, and marker drugs. Miranda at 4762 (section 2.4). Dr. Zizic, Dr. Rose, and Dr. Moy had different opinions as to the soundness of this methodology. In his oral testimony, Dr. Zizic presented Supplemental Table 1. This supplemental table shows that no marker drugs were associated with SLE. Tr. 723. Dr. Zizic also maintained that the researchers would not capture the “vast majority of lupus cases” because people with lupus are rarely hospitalized. Tr. 724. He estimated one in 10,000 cases of lupus would be hospitalized. Tr. 723. In contrast, Dr. Rose and to a lesser extent Dr. Moy defended the methodology. The researchers also look at “long-term illness reimbursement records.” Miranda at 4762. These records, according to Dr. Rose and Dr. Moy, would identify people suffering from SLE because SLE is a chronic disease. Tr. 438, 693-94, 757. Dr. Zizic did not refute the point regarding reimbursement records for long-term illnesses. Dr. Zizic’s criticisms were further undone by the results in Miranda. Miranda and colleagues identified 184 patients with lupus. Miranda at 4764 (Table 3). Among the unvaccinated, 139 cases of lupus were found with an incidence rate of 3.42. Id. Among the vaccinated, 45 cases were found with an incidence rate of 3.23. Id. When these numbers were pointed out to Dr. Zizic, he conceded the authors’ ability to detect cases in either group would be the same. Tr. 749. Having determined the incidence rate for cutaneous or systemic lupus erythematosus among the unvaccinated vaccinated populations,17 the researchers determined a hazard ratio (“HR”).18 The unadjusted hazard rate was 0.97 with a 17 A less significant criticism from Dr. Zizic was combining cutaneous lupus with systemic lupus erythematosus. Tr. 723. But, this contention was easily countered by Dr. Rose, who opined without contradiction that SLE is much more common. Tr. 438-39. 18 “A hazard ratio is used in epidemiological studies to compare two populations with hazard functions by dividing the risk of a particular event by the baseline risk. Gerald Van Belle, Statistical Rules of Thumb, 130 (2nd ed. 2008). If the hazard ratio is less than one, the second group is less affected than the first. Stanton Glantz, Primer of Bio-statistics, 388 (4th ed. 1997). If the hazard ratio is greater than one, the second group is more affected than the first. Id. If the hazard ratio is one, the groups are affected at equal rates. Id.” Spahn v. Sec'y of Health & Hum. Servs., No. 09-386V, 2014 WL 12721080, at *11 n.17 (Fed. Cl. Sept. 11, 2014), mot. for rev. denied, 133 Fed. Cl. 588, 603 (2017). 24 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 25 of 48 95% confidence interval of 0.67-1.39. Miranda at 4764 (Table 3). The adjusted hazard rate was minimally increased: 1.01 (95% CI: 0.69-1.48). Miranda at 4765 (Figure 1). The authors concluded: “our study provides reassuring results with respect to the risk of AID after HPV vaccination, confirming the results of previous epidemiological studies.” Miranda at 4767. 6. Liu Dr. Rose also cited a 2018 study by Karen Liu and others. Exhibit T. This article was not included in the Wang meta-analysis. Tr. 498. These researchers used databases from Ontario, Canada. “The study cohort consisted of 290 939 girls aged 12-17 years who were eligible for vaccination between 2007 and 2013.” Liu at E648; accord Tr. 470. After determining when the young women received and HPV vaccine, researchers focused on illnesses appearing within sixty days of the vaccination. Liu at E650. In Dr. Zizic’s report, he criticized the use of a 60-day window, although Dr. Zizic did not testify about Liu orally. Dr. Rose stated a risk period of 60 days more likely conforms to what is biologically plausible. Tr. 471. Dr. Rose also pointed out that the authors expended the window in a sensitivity analysis to 180 days. Liu at E650. The authors stated this study “had more than 90% power to detect a rate ratio of 2.0 for autoimmune disorders.” Id. For “systemic autoimmune rheumatic diseases,” the adjusted rate ratio was 1.21 with a 95% confidence interval of 0.57-2.57. Liu at E653 (Figure 3), Tr. 472. The category of systemic rheumatic diseases includes systemic lupus erythematosus, system sclerosis, Sjorgen’s syndrome, dermatomyositis, and polymyositis. Liu at E653 (Figure 3: caption). Dr. Rose persuasively explained why including other diseases with SLE would not affect the analysis. Tr. 472. The authors concluded: “This large population-based study did not find a significant risk of autoimmune disorders following HPV4 vaccination among girls aged 12-17 years. . . . These findings add to the growing body of evidence on the safety of this vaccine.” E654. 7. Jorgensen With Ms. Stricker’s Prehearing Reply, filed on July 22, 2020, she submitted an article written by Lars Jorgensen and others published in 2020. Exhibit 82. The researchers gained access to 79% of clinical study reports, which underlie the 25 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 26 of 48 report of HPV vaccine safety that the vaccine manufacturer submitted to European regulatory agencies. Jorgensen at 3, Tr. 245-47. After gathering these clinical safety reports, the authors extracted some data and conducted a meta-analysis. In doing so, Jorgensen and colleagues focused on various outcomes. Jorgensen at 3. This list did not include lupus. Tr. 317-19. The researchers concluded that the manufacturer’s safety studies contained a “high risk of bias.” Jorgensen at 7. The reason for bias was that nearly all controls “received an active comparator such as HPV vaccine aluminum-containing adjuvants.” Id. Dr. Zizic explained that the controls did not receive a placebo. Instead, the controls, like the vaccinated populations, received an adjuvant. Tr. 248-49, see also Tr. 316 (Dr. Rose). The authors suggested that for some conditions (but not lupus), HPV vaccines may cause more harm than previously reported. Jorgensen at 15. Due to the relative newness of the Jorgensen study, the undersigned submitted an article about Jorgensen before the hearing. Order, issued January 10, 2022, see also Tr. 703-04. This author opined that Jorgensen “demonstrates the risk of relying too much on CSR’s [clinical study reports].” Bastian at 41. Dr. Zizic described Bastian’s comments as “unsubstantiated.” Tr. 250. Further assessment of the details of Jorgensen and Bastian’s criticism is not required. Jorgensen did not provide any information helpful to determining whether HPV vaccines can cause SLE. See Tr. 317-19. 8. Grimaldi-Bensouda Dr. Rose presented a different type of study by Grimaldi-Bensouda and others, published in 2016. The source of information was a French database, known as the PGRx autoimmune disease study group. Tr. 549. Board-certified specialists place information about people with autoimmune diseases into the database and general practitioners refer other people who can act as controls. Grimaldi-Bensouda at 83. The methodology was to find people with a disease and then look backwards to see if a person with the disease had been vaccinated. Tr. 549. SLE was a disease of interest. Grimaldi-Bensouda at 85 (section 2.2); Tr. 551. The crude odds ratio for SLE was 0.78 with a 95% confidence interval of 0.40-1.52. Grimaldi-Bensouda at 85 (table 2), Tr. 550.19 19 Dr. Rose appears to discuss the odds ratio for all autoimmune diseases when he describes the odds ratio as 0.58. See Grimaldi-Bensouda at 85. 26 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 27 of 48 The authors concluded: “the ongoing surveillance of HPV vaccination using the PGRx information system showed no increased risk of ADs [autoimmune diseases] among young females.” Grimaldi-Bensouda at 89; accord Tr. 550-51. 9. Summary The reliable controlled studies do not support a finding that an HPV vaccine can cause systemic lupus erythematosus. Four studies (Chao, Arnheim-Dahlström, Miranda, and Liu) did not detect an increased incidence of SLE following HPV vaccination. The study populations were large---more than one hundred thousand people in each of the four studies and more than two million people in Arnheim- Dahlström and Miranda. Ms. Stricker attempted to undermine the methodologies. However, she failed to show any significant flaw for Arnheim-Dahlström, Miranda, or Liu. Their methods appear reliable and the conclusions that the HPV vaccine does not increase the incidence of SLE are fair. For Chao, the evidence regarding methodology is mixed. Ms. Stricker can legitimately point to a non-standard technique for filling in missing data, which was not really missing. But even if Chao were excluded, the Arnheim-Dahlström, Miranda, and Liu articles still indicate that researchers have not detected an increased incidence. The only researchers to purport to detect an increased incidence are Geier and Geier. However, their methodology is suspect, and any results are not reliable. This rejection of Geier and Geier causes a corresponding rejection of Wang. The Grimaldi study, which approached the question of whether an HPV vaccination is safe from a different perspective, tends to corroborate the findings of Chao, Arnheim-Dahlström, Miranda, and Liu. Although this study is smaller (involving approximately 2,300 people), HPV vaccination was not statistically associated with SLE. B. Studies on the Effect of Vaccination The next type of study concerns how vaccines affect people. Ms. Stricker introduced two articles on this topic, one by M. Abu-Shakra and the other by Natasha Toplak. The Secretary presented one by J. Patricia Dhar. In the 2002 Abu-Shakra study, the researchers gave 24 women with SLE a flu vaccine. Abu-Shakra at 369, Tr. 489. The researchers found that various antibodies, including antibodies associated with lupus, increased 6 and 12 weeks after the vaccination. Abu-Shakra at 370-71, Tr. 191-92. 27 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 28 of 48 While the levels of antibodies changed, “the generation of anti-ENA [extractable nuclear antigen] was not associated with a specific clinical response.” Abu-Shakra at 372; accord Tr. 192-93. The researchers also noted “we have shown [in a different paper] that influenza virus vaccine is safe for patients with SLE.” Abu-Shakra at 371; accord Tr. 489. In the present paper, Abu-Shakra concluded: “Patients with SLE should be encouraged to receive the influenza vaccine.” Abu-Shakra at 372. Dr. Zizic stated that he would not conclude the flu vaccine was safe. Tr. 193. To him, the antibodies that were produced after vaccination would cause damage. Tr. 192. The patients in the Abu-Shakra study did not have adverse consequences because, according to Dr. Zizic, they were being treated for lupus. Tr. 193. When asked about the people in Abu-Shakra receiving a flu vaccine versus the HPV vaccination that Ms. Stricker received, Dr. Zizic’s response was the HPV vaccine is the “same difference.” Tr. 194, accord Tr. 327. On the other hand, Dr. Rose harmonized the increase in antibodies and the lack of clinical manifestations differently. Dr. Rose stated that fluctuations in antibodies do not mean much. Rheumatologists care about only a few antibodies that might correlate to disease severity. Tr. 492-93. Next, Natasha Toplak and colleagues conducted a somewhat similar experiment, which was reported in 2008. The researchers gave flu vaccine to 92 “apparently healthy adults.” Toplak at 135. Although the researchers described them as “apparently healthy,” Dr. Rose pointed out that a large fraction (24%) tested positive for ANA antibodies before the vaccination. Tr. 486; see also Toplak at 136 (Table 1). The researchers determined the number of volunteers who tested positive for antibodies before the vaccination, one month after the vaccination, and six months after the vaccination. Toplak at 136, Tr. 485. Some people experienced an increase in antibodies. Toplak at 136. The authors did not show how much any antibody increased. Tr. 487. The authors did not present any controls, meaning people who were not vaccinated. Tr. 488. Dr. Rose orally testified that this paper did not show anything of significance. Tr. 486-87. Dr. Zizic barely mentioned Toplak in his oral testimony. Tr. 327. A third study was reported by J. Patricia Dhar in 2017. Exhibit W. Dr. Rose described it as a “clinical trial.” Tr. 553. In this study, 34 “women ages 18-50 years with a history of mild to moderate SLE (and no other autoimmune disease) and minimally active or inactive SLE volunteered to participate in the study.” Dhar at 2643; accord Tr. 553. The participants were all vaccinated with the qHPV 28 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 29 of 48 Gardasil vaccine. Dhar at 2642. The researchers determined whether the subjects experience an SLE flare. The researchers found “no instance of SLE flare.” Dhar at 2645. Dr. Rose interpreted this finding as “indirect evidence that [HPV vaccination is] not related to at least the mechanism of lupus exacerbation.” Tr. 554. Overall, these types of studies do not meaningfully support Ms. Stricker’s claim that the HPV vaccine can cause SLE. She submitted two articles which are at least one step removed from situation in that Abu-Shakra and Toplak studied the flu vaccine, not the HPV vaccine. More importantly, neither Abu-Shakra nor Toplak showed the people with SLE who received the flu vaccine got worse. This lack of worsening was also evident in Dhar, which involve the HPV vaccine. If the HPV vaccine were causing a worsening of disease, then the results could have appeared in Dhar. C. Case Reports / Case Series Another type of evidence is either a case report or a case series. See Tr. 512 (defining a “case series” as an article with more than one case report). Ms. Stricker contributed two: articles by HF Soldevilla and Mariele Gatto. Dr. Zizic testified orally about Gatto but not much about Soldevilla. See Tr. 199-202. Various authorities have commented on the value of case reports. To start, the Federal Judicial Center has published a series of guides designed “to assist judges . . . in reaching an informed and reasoned assessment concerning the basis of expert evidence.” Jerome P. Kassirer and Gladys Kessler, Reference Manual on Scientific Evidence, Preface (3d ed. 2011) (“Reference Manual”). The guidance from the Federal Judicial Center translates to the Vaccine Program because causation for off-Table injuries in the Vaccine Program is the same as traditional causation. See Moberly, 592 F.3d at 1322-23; Shyface v. Sec'y of Health & Human Servs., 165 F.3d 1344, 1351 (Fed. Cir. 1999) (“The absence of elaboration of the law of causation in the legislative history leads us to conclude that the Vaccine Act's requirement of causation in non-Table cases was not viewed as distinct from causation in the tort law.”). For examples in which appellate authorities within the Vaccine Program have cited the Reference Manual, see Germaine v. Sec’y of Health & Hum. Servs., 155 Fed. Cl. 226, 228-29 (2021), and Hart v. Sec’y of Health & Hum. Servs., 60 Fed. Cl. 598, 607 n.20 (2004). A pertinent guide in the Reference Manual states “[a]necdotal evidence usually amounts to reports that events of one kind are followed by events of 29 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 30 of 48 another kind. Typically, the reports are not even sufficient to show association, because there is no comparison group.” David H. Kaye and David A. Freedman, Reference Manual on Scientific Evidence, Reference Guide on Statistics, at 218. These authors also state “some courts have suggested that attempts to infer causation from anecdotal reports are inadmissible as unsound methodology under Daubert.” Id. at 217 n. 14 (citing cases). Within the Vaccine Program, the Federal Circuit has endorsed, albeit indirectly, a view that case reports merit little weight. In a series of five cases involving auto-immune hepatitis, the (undersigned) special master rejected case reports as evidence of causation. Porter v. Sec’y of Health & Hum. Servs., No. 99–639V, 2008 WL 4483740, at *13 (Fed. Cl. Spec. Mstr. Oct. 2, 2008). Under the caption of a different case, a judge at the Court of Federal Claims disagreed with this weighing of evidence. Rotoli v. Sec’y of Health & Hum. Servs., 89 Fed. Cl. 71, 86–87 (2009). When the Federal Circuit reviewed the special master's decision, the Federal Circuit stated that “[t]he special master found that the remaining two articles, both describing single case studies, did not contain any meaningful analysis about causation.” Porter v. Sec’y of Health & Human Servs., 663 F.3d 1242, 1253 (Fed. Cir. 2012). The Federal Circuit also stated that the “decision reveals a thorough and careful evaluation of all the evidence including . . . medical literature.” Id. at 1254. Similar indirect support from the Federal Circuit is found in W.C. v. Sec’y of Health & Hum. Servs., No. 07-456V, 2011 WL 4537877, at *13 (Fed. Cl. Spec. Mstr. Feb. 22, 2011), mot. for rev. denied on this point, 100 Fed. Cl. 440, 456 (2011), aff’d, 704 F.3d 1352 (Fed. Cir. 2013). At the trial level, the (undersigned) special master declined to rely upon case reports because, among other reasons, “case reports cannot distinguish a temporal association from a causal relationship.” Id. at *13. At the Federal Circuit, the appellate court focused primarily upon epidemiologic studies, which undermined the claim that the vaccine significantly aggravated the petitioner’s illness. W.C. v. Sec’y of Health & Hum. Servs., 704 F.3d 1352, 1360-61 (Fed. Cir. 2013). However, at the end of its opinion, the Federal Circuit stated that it “cannot say that the special master’s . . . weighing of the scientific evidence was arbitrary or capricious.” Id. at 1361. Much of the foregoing analysis regarding case reports was set forth in K.O. v. Sec’y of Health & Human Servs., No. 13-472V, 2016 WL 7634491, at *11-12 (Fed. Cl. Spec. Mstr. July 7, 2016). After K.O., the Federal Circuit has not discussed case reports in a precedential opinion, leaving Porter and W.C. as the leading, although muted, words on the subject. Consequently, judges from the Court of Federal Claims have tended to defer to the special master’s assessment of 30 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 31 of 48 case reports. See, e.g., Kelly v. Sec’y of Health & Hum. Servs., 160 Fed. Cl. 316, 319 (2022) (indicating that the special master was not arbitrary in finding that case reports have limited or nonexistent value); Rus v. Sec’y of Health & Hum. Servs., 129 Fed. Cl. 672, 682 (2016) (noting the special master could reasonably afford little weight to the medical literature, including case reports). An exception to this trend is Patton v. Sec’y of Health & Hum. Servs., 157 Fed. Cl. 159 (2021). In Patton, the Court ruled that the special master “erred in his prong one analysis by discounting the evidentiary value of the case reports [petitioner’s expert] submitted.” Id. at 168. But, Patton does not discuss Porter or W.C. Instead, Patton relies upon Paluck v. Sec’y of Health & Hum. Servs., 104 Fed. Cl. 457, 475 (2012).20 Outside of the Vaccine Program, district courts have examined the value of case reports in the context of claims that drugs or a medical device harmed a person. Recent examples include: In re: Abilify (Aripriprazole) Products Liability Litigation, 299 F.Supp.3d 1291, 1309 (N.D. Fla. 2018) (“The difficulty with case reports is distinguishing between association and causation”); In re Tylenol (Acetaminophen) Marketing, Sales Practice, and Products Liability Litigation, 198 F.Supp.3d 446, 461 (E.D. Pa. 2016) (“It is true that case reports and anecdotal evidence alone may not be sufficient support for a causation opinion. . . . However, case reports considered in conjunction with other evidence may be an appropriate basis for an expert’s causation opinion.”); In re Mirena IUD Products Liability Litigation, 169 F.Supp.3d 396, 451 (S.D.N.Y. 2016) (“Case reports are generally disfavored by courts as evidence of causation because they merely describe ‘reported phenomena without comparison to the rate at which the phenomena occur in the general population or in a defined control group; [they] do not isolate and exclude potentially alternative causes; and [they] do not investigate or explain the mechanism of causation.’”) (citation omitted). Testimony from Dr. Rose and Dr. Moy confirms that case reports are generally not effective ways to show causation. Tr. 512, 669-71. There are 20 Paluck states “case reports ‘do not purport to establish causation definitively, and this deficiency does indeed reduce their evidentiary value. Nonetheless, the fact that case reports can by their nature only present indicia of causation does not deprive them of all evidentiary weight.’” Paluck, 104 Fed. Cl. at 475, quoting Campbell v. Sec’y of Health & Hum. Servs., 97 Fed. Cl. 650, 668 (2011). The case Paluck quotes, Campbell, cites to Rotoli v. Sec’y of Health & Hum. Servs., 89 Fed. Cl. 71, 86-87 (2009). However, the value of the opinion by the Court of Federal Claims seems questionable as the Federal Circuit, as noted above, reversed the outcome in Rotoli, and reinstated the special master’s decision, which gave little weight to the case reports. Porter, 663 F.3d at 1253. Paluck, which cited Rotoli, was issued before the Federal Circuit reversed Rotoli. 31 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 32 of 48 additional problems with Soldevilla and with Gatto. Dr. Moy criticized Soldevilla and Gatto for their lack of controls, unclear diagnoses, and inferences drawn from temporal proximity. Tr. 512-16. He did not think these cases were reliable, or representative of Ms. Stricker’s case. Id. Likewise, Dr. Rose testified that neither Soldevilla nor Gatto established causation, and criticized their reliance on temporal association. Tr. 670-71; see also Exhibit L at 20-21. Accordingly, although the case reports have been considered, they are given little weight. Overall, the studies submitted by the parties tend to undermine a claim that the HPV vaccine can cause SLE. However, these studies cannot prove a negative. Therefore, the theories Ms. Stricker presented are addressed next. D. Theories Ms. Stricker proposed two theories by which HPV vaccine can cause SLE. The theory that received the most attention, by far, was molecular mimicry. The other less prominent theory involved Granzyme B. 1. Molecular Mimicry Because special masters are often called upon to evaluate the persuasiveness of the theory of molecular mimicry, the Court of Federal Claims and the Court of Appeals for the Federal Circuit have considered molecular mimicry in their appellate role. In December 2019, the undersigned identified the leading precedents as W.C. v. Sec’y of Health & Hum. Servs., 704 F.3d 1352 (Fed. Cir. 2013), and Caves v. Sec’y of Dep’t. of Health & Hum. Servs., 100 Fed. Cl. 119 (2011), aff’d sub nom., 463 F. App’x 932 (Fed. Cir. 2012). Tullio v. Sec’y of Health & Hum. Servs., No. 15-51V, 2019 WL 7580149, at *12-14 (Fed. Cl. Spec. Mstr. Dec. 19, 2019), mot. for rev. denied, 149 Fed. Cl. 448 (2020). While Tullio describes those cases in more detail, their essence appears to be that although molecular mimicry is accepted in some contexts, special masters may properly require some empirical evidence to show that a particular vaccine can cause a particular disease. In the next approximately three years, appellate authorities reviewing decisions involving molecular mimicry have generally endorsed the approach of looking for some evidence that persuasively shows that a portion of a vaccine resembles a portion of human tissue, which contributes to causing the disease, and 32 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 33 of 48 that the immune system will respond to the relevant amino acid sequence.21 Chronologically, the list of more recent appellate cases begins with the opinion in Tullio, which denied the motion for review. 149 Fed. Cl. 448, 467-68 (2020). Another example in which the Court of Federal Claims held that the special master did not elevate the petitioner’s burden of proof in the context of evaluating the theory of molecular mimicry is Morgan v. Sec’y of Health & Hum. Servs., 148 Fed. Cl. 454, 476-77 (2020), aff’d in non-precedential opinion, 850 F. App’x 775 (Fed. Cir. 2021). In Morgan, the Chief Special Master found that petitioner had not presented persuasive evidence about a relevant antibody. Id. at 477. The Chief Special Master also noted that the articles about the relevant disease do not list the wild flu virus as potentially causing the disease. Id. When examining this analysis, the Court of Federal Claims concluded: “the Chief Special Master did not raise the burden of causation in this case; petitioner simply failed to meet it.” Id. The Federal Circuit also evaluated the Chief Special Master’s approach in Morgan. The Federal Circuit concluded: “We discern no error in the special master’s causation analysis.” 850 F. App’x 775, 784 (Fed. Cir. 2021). Most other recent appellate cases follow this path. See, e.g., Duncan v. Sec’y of Health & Hum. Servs., 153 Fed. Cl. 642, 661 (2021) (finding the special master did not err in rejecting a bare assertion of molecular mimicry); Caredio v. Sec’y of Health & Hum. Servs., No. 17-79V, 2021 WL 6058835, at *11 (Fed. Cl. Dec. 3, 2021) (indicating that a special master did not err in requiring more than homology and citing Tullio); Yalacki v. Sec’y of Health & Hum. Servs., 146 Fed. Cl. 80, 91-92 (2019) (ruling that special master did not err in looking for reliable evidence to support molecular mimicry as a theory); but see Patton v. Sec’y of Health & Hum. Servs., 157 Fed. Cl. 159, 169 (2021) (finding that a special master erred in requiring petitioner submit a study to establish medical theory causally connecting flu vaccine to brachial neuritis). A foundation for the molecular mimicry theory in this case is a belief that the development of lupus requires both a genetic disposition and an environmental factor. See Doria at 25. Infections such as from viruses have been proposed as 21 The term “homology” is used when discussing molecular mimicry. “Homology” is defined as “the quality of being homologous; the morphological identity of corresponding parts; structural similarity due to descent from a common form.” Dorland’s at 868. 33 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 34 of 48 potential triggers. Rose at 381. The Epstein-Barr virus has been theorized as one agent contributing to the pathogenesis of SLE. Doria at 25, Tr. 184. The basic theory of molecular mimicry is that some components of an antigen resemble a human being’s own tissue. This concept is called “homology.” A person’s immune system cross-reacts and mistakenly targets the host’s tissue. An article Dr. Zizic introduced, Kanduc, demonstrated that viruses and people have extensive homology. Kanduc at 1396, Tr. 461. Kanduc suggested that the commonness of homology undermines the idea that viral infections lead to autoimmune disease. Tr. 461; but see Tr. 312-13, 785-87. Kanduc commented that after “three decades of intensive research in the field, a causative link between molecular mimicry and human autoimmune disease is still sub judice and the molecular mimicry hypothesis has received no validation.” Kanduc at 1395. With respect to this commentary, Dr. Rose rhetorically asked: “if there is no proof, why should we accept [molecular mimicry] as happening in this case?” Tr. 463. Although Dr. Zizic testified in rebuttal, Dr. Zizic did not effectively answer Dr. Rose’s question. However, earlier, Dr. Zizic put forward the Segal article as supporting molecular mimicry. To support the theory that the HPV vaccine has homology with parts of the human body involved in SLE, Dr. Zizic heavily relied upon a 2017 article by Yahel Segal, Yehuda Shoenfeld, and others. See Tr. 194-99. These researchers searched databases containing the amino acids sequences of the HPV L1 protein, which is part of the HPV vaccine, and “human proteins that when altered, are associated with SLE.” Segal at 567; accord Tr. 454. The authors presented their findings in Table 1, which received much attention during the hearing. In Dr. Zizic’s view, “a multiplicity of pentapeptides shared by the herpes papillomavirus of the same strains that are in the vaccine that end up causing the functional problems that lead to autoimmune disease particularly lupus in these patients.” Tr. 198. He concluded “the diseases on the right hand side [of Table 1] are resulting from the proteins that are involved in lupus that are peptide sharing with the virus.” Tr. 199. Contrastingly, Dr. Rose indicated the findings had more limited significance. When asked on cross-examination whether “Table 1 reflects identity homology between the HPV L1 capsid protein and various host tissue known to be amino pathogenic for lupus,” Dr. Rose responded, “the word amino pathogenic is not correct.” Tr. 595. Dr. Rose distinguished between autoantibodies that are “associated with” lupus and autoantibodies that could be pathogenic. Tr. 34 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 35 of 48 595-96. Dr. Rose went on to assert that labeling a column in Table 1 as SLE- associated proteins is “misleading.” Tr. 597. In rebuttal, Dr. Zizic did not persuasively counter Dr. Rose’s point regarding (the lack of) proof for pathogenesis. Discussing peptides that are part of complement, Dr. Zizic stated an antibody’s attack on complement could interfere with the complement system and end up causing lupus. But, according to Dr. Zizic, “we can’t prove that. All I’m saying is there’s great biologic plausibility.” Tr. 735. Dr. Zizic stated “it is very conceivable… If you form an antibody against the components of complement, they can no longer fit in the complement cascade… And end up with autoimmune disease, including lupus.” Tr. 736. In addition to questioning the pathological relevance, Dr. Rose raised a second point. Dr. Rose also opined that any pentapeptides listed in Table 1 “has to be antigenically relevant, meaning that they have to be able to generate antibodies.” Tr. 455-56, accord Tr. 518, 764. The pentapeptide’s ability to lead to a production of antibodies depends, in part, on its location in a cell. Tr. 456. Dr. Zizic did not persuasively rebut Dr. Rose’s point. In short, Dr. Rose’s interpretation of the Segal paper hits the target. Any statement that antibodies to specific proteins cause lupus would exaggerate what is known. See A.F. v. Sec’y of Health & Hum. Servs., No. 19-466V, 2023 WL 251948, at *25 (Fed. Cl. Spec. Mstr. Jan. 18, 2023) (indicating that a different paper by Segal and Shoenfeld offered homology based on “non-substantiated contentions about amino acid sequencing”). The triggers for lupus are not known. Tr. 306 (Dr. Zizic), 404 (Dr. Rose); see also Parks (exhibit H). Accordingly, while Segal and others have identified homologous sequences of five amino acids, there has not been any persuasive showing that an attack on these pentapeptides would cause lupus. The finding of pentapeptide similarity might be enough to generate some interest to conduct more experiments. Tr. 458; see also Tr. 595 (describing homology as “one step”), Tr. 765 (describing Kanduc as the first step). Stating that the evidence in this case is insufficient to credit molecular mimicry as a theory by which HPV vaccine can cause SLE is not the same as requiring scientific certainty. Petitioners do not need to prove causation beyond a reasonable doubt. Petitioners need only evidence that preponderates. Zatuchni v. Sec'y of Health & Hum. Servs., 69 Fed. Cl. 612, 622 (2006). However, many appellate cases have sustained decisions by special masters that rejected molecular mimicry. See, e.g., Morgan, 850 F. App’x 775 (Fed. Cir. 2021); Duncan, 153 Fed. Cl. 642 (2021); Yalacki, 146 Fed. Cl. 80 (2019). So, too, in this case, Ms. Stricker has failed to meet her burden of proof. 35 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 36 of 48 2. Granzyme B Ms. Stricker may have presented a second theory involving Granzyme B and defective clearance. See Tr. 168, 259-65, Petitioner’s Posthear’g Br. at 56-57; But see Pet’r’s Posthear’g Br. at 29 (“Dr. Zizic’s expert medical theory is based upon molecular mimicry”). However, this theory has been confusing for a long time. Although Dr. Zizic mentioned defective cell clearance in his first report (Exhibit 37 at 31), the undersigned commented in the March 12, 2019 status conference that the theory was not explained well. In the intervening years, Ms. Stricker and Dr. Zizic have not submitted evidence clarifying the theory. Whether Granzyme B and/or defective cell clearance might contribute to the cause of systemic lupus erythematosus is debatable. However, the details of arguments can be set aside for a more fundamental reason. Even if Granzyme B and/or defective cell clearance were a part of the pathogenesis for SLE, Ms. Stricker has not connected the HPV vaccine to Granzyme B and/or defective cell clearance. The lack of connection is most notable in the section of Ms. Stricker’s posthearing brief on defective cell clearance and Granzyme B. Over the course of one and one-half pages here, Ms. Stricker does not mention the HPV vaccine at all. She also does not return to defective cell clearance and/or Granzyme B in her posthearing reply. On cross-examination, Dr. Zizic admitted Granzyme B “has nothing to do with infection or vaccination.” Tr. 297. Accordingly, Ms. Stricker has failed to demonstrate how a theory involving Granzyme B and/or defective cell clearance explains how the HPV vaccine can cause SLE. E. Summary on Theory As discussed, the primary theory by which Ms. Stricker attempts to show a way by which the HPV vaccine can cause SLE is molecular mimicry. However, the evidence, considered as a whole, is lacking. Large-scale epidemiologic studies involving millions of people have not detected an increased incidence of SLE following the HPV vaccination. The Dhar study, which involved fewer than 100 people, indicated that people with SLE can receive the HPV vaccine without worsening their disease. The article most directly discussing molecular mimicry in the context of the HPV vaccine and SLE (Segal) lacks persuasive value. None of these points is dispositive by itself. But, taken as a whole, the evidence does not support a finding that the HPV vaccine can cause SLE. A finding that Ms. Stricker has failed to meet one of the Althen prongs means that she is not entitled to compensation. Nevertheless, the additional Althen prongs are reviewed for completeness, although they are taken out of order. 36 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 37 of 48 V. Althen Prong 3 The third Althen prong requires “a showing of a proximate temporal relationship between vaccination and injury.” Althen, 418 F.3d at 1278. The timing prong actually contains two parts. A petitioner must show the “timeframe for which it is medically acceptable to infer causation” and the onset of the disease occurred in this period. Shapiro v. Secʼy of Health & Hum. Servs., 101 Fed. Cl. 532, 542-43 (2011), recons. denied after remand on other grounds, 105 Fed. Cl. 353 (2012), aff’d without op., 503 F. App’x 952 (Fed. Cir. 2013). Dr. Moy proposed that if HPV vaccine can cause SLE, then a medically appropriate interval is 4 to 6 weeks. Exhibit A at 6. For Ms. Stricker, Dr. Moy’s definition means the SLE must have begun to manifest between October 27, 2015 and November 10, 2015. Resp’t’s Posthear’g Br. at 24. Although the Secretary contends Ms. Stricker’s lupus was not apparent until November 26, 2015 (Resp’t’s Posthear’g Br. at 25), persuasive evidence shows that the onset was on approximately November 1, 2015. Thus, if molecular mimicry had been accepted as a reliable theory in the context of HPV vaccines causing SLE, then Ms. Stricker could have met her burden on prong three. A finding that a vaccinee’s disease began shortly after vaccination is not a sufficient basis to find causation. Grant v. Sec’y of Health & Hum. Servs., 956 F.2d 1144 (Fed. Cir. 1992) (“Temporal association is not sufficient, however, to establish causation in fact.”). In addition to presenting a sequence of events, Ms. Stricker is obligated to present a causal theory and to show a logical sequence of cause and effect. For the reasons, explained above in Section IV, Ms. Stricker did not meet her burden regarding theory. Whether she meets her burden regarding the second Althen prong is discussed next. VI. Althen Prong 2 The second Althen prong requires “a logical sequence of cause and effect showing that the vaccination was the reason for the injury.” Althen, 418 F.3d at 1278. As a matter of logic, when a petitioner fails to meet their burden to show that a vaccine can cause an injury, the petitioner also fails to show that a vaccine did cause their injury. The lack of evidentiary support for the first Althen prong may be considered in the analysis of the other Althen prongs. See Temes v. Sec’y of Health & Hum. Servs., 151 Fed. Cl. 448, 464 (2020); Caves v. Sec’y of Health & Hum. Servs., 100 Fed. Cl. 119, 145 (2011). However, for sake of completeness, 37 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 38 of 48 the evidence on this point is discussed as well.22 Ms. Stricker’s evidence primarily consists of Dr. Zizic’s opinion, a letter from her rheumatologist, and a letter from her primary care physician. See Pet’r’s Posthear’g Br. at 58-64. To conclude that the HPV vaccine did cause Ms. Stricker’s SLE, Dr. Zizic relies upon the temporal interval. See Exhibit 37 (first report) at 43, Tr. 166. Ms. Stricker declined from being apparently healthy and without signs or symptoms of SLE before the vaccination to developing fatigue and muscle pain in early November. Otherwise, Dr. Zizic describes a progression of signs and symptoms for SLE. Dr. Zizic’s reliance on the temporal sequence is not wrong. Appropriate timing is required in all cases. But, Dr. Zizic does not identify any facts about Ms. Stricker that suggest her lupus was due to the vaccine. See Pet’r’s Br. For example, Ms. Stricker emphasizes that her mother’s multiple sclerosis makes Ms. Stricker at greater risk for developing an autoimmune disease. Pet’r’s Posthear’g Br. at 58, citing Tr. 599 (Dr. Rose’s testimony). But, this greater risk does not necessarily mean a greater risk for an adverse reaction to the HPV vaccine. Dr. Zizic also attempts to rule out other potential causes for Ms. Stricker’s lupus. An HPV infection and tetracycline use are discussed below. If, for sake of argument, it is assumed that Dr. Zizic ruled these potential alternative causes out, then Ms. Stricker still must do more to meet her burden under Althen. Moberly v. Sec’y of Health & Hum. Servs., 592 F.3d 1315, 1323 (Fed. Cir. 2010). In addition to Dr. Zizic, Ms. Stricker relies upon letters from two treaters, Dr. Saba and Dr. Robinson. The opinions of treating doctors can be quite probative. Cappizano v. Sec’y of Health & Hum. Servs., 440 F.3d 1317, 1326 (Fed. Cir. 2006). However, the views of a treating doctor are not absolute. Snyder v. Sec’y of Health & Hum. Servs., 88 Fed. Cl. 706, 745 n.67 (2009). Dr. Saba. Dr. Saba concludes her January 31, 2018 letter by saying the idea that the HPV vaccine caused Ms. Stricker’s connective tissue disease was “very possible.” Exhibit 22. However, statements from treaters about possibilities provide little, if any, assistance to petitioners who must establish their cases with preponderate evidence. See Paterek v. Sec’y of Health & Hum. Servs., 527 F. App’x 875, 883 (Fed. Cir. 2013) (“testimony that causation was ‘not impossible’ fails to provide support for causation at all”); Austin v. Sec’y of Health & Hum. Servs., 141 Fed. Cl. 268, 280 (2018) (special master was not arbitrary in not 22 Evidence regarding alternative causes is discussed below in Section VII. 38 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 39 of 48 crediting a statement from a treating doctor who described causation as “possible”); Doe v. Sec’y of Health & Hum. Servs., 19 Cl. Ct. 439, 450 (1990) (a treater’s statement that causation was “highly possible” does not assist petitioner in presenting preponderant evidence). Dr. Robinson. Dr. Robinson is a primary care doctor, not Ms. Stricker’s rheumatologist. See Tr. 57. Dr. Robinson stated that based upon the temporal sequence, “it does seem likely that [Ms. Stricker’s] autoimmune disease was triggered by the vaccine.” Exhibit 23. The testifying experts acknowledged Dr. Robinson’s letter. Tr. 238, 621, 696. The Secretary challenges the letters from the treating doctors because the treaters may not have received Ms. Stricker’s “complete medical records,” and they may not have “conducted any substantial independent research.” Resp’t’s Br. at 20.23 Ms. Stricker replied that reviewing complete medical records “has never been a requirement in the Vaccine Program, and Respondent cites to no authority to support this requirement as none exists.” Pet’r’s Posthear’g Reply at 11. Similarly, according to Ms. Stricker, “treating physicians have no requirement of conducting independent research, as they are not expert witnesses.” Id. Special masters may award petitioners compensation based upon “medical records.” 42 U.S.C. § 300aa–13(a)(1). Dr. Robinson’s January 9, 2018 letter constitutes a medical record. As such, it constitutes evidence supporting Ms. Stricker’s claim. If Ms. Stricker had established Althen prong one and if alternative causes were ruled out, then Dr. Robinson’s letter may have been sufficient to win the case for Ms. Stricker. See Langland v. Sec’y of Health & Hum. Servs., 109 Fed. Cl. 421, 438 (2013) (“Federal Circuit precedent makes it evident that the first prong of Althen must be proven before the opinions of treating physicians may clinch causation under the other prongs”). However, for reasons explained above, Ms. Stricker has not established the first condition – proof on prong 1. As to the second condition – a ruling out of other causes, that question is addressed next. 23 The Secretary cites in part, transcript pages 73-76 and 95. It is not clear how these citations advance the Secretary's argument. 39 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 40 of 48 VII. Potential Alternative Causes Here, the record includes suggestions that two substances, unrelated to the HPV vaccination, could have caused Ms. Stricker’s illness. These are her use of tetracyclines and her exposure to the HPV virus. A. Tetracyclines Ms. Stricker started using minocycline for her acne in 2010. Tr. 97, 113. She used it until August 2015, when her acne returned. Tr. 31, 97. Her dermatologist switched her medication from minocycline to doxycycline. Tr. 97, Exhibit 11 at 6 (Aug. 11, 2015). Ms. Stricker stopped taking all tetracyclines by mid-November 2015. Tr. 98, 113. Ms. Stricker’s use of minocycline and doxycycline are the foundation for Dr. Rose’s idea that Ms. Stricker suffered from drug-induced lupus. See Tr. 529. Drug-induced lupus is not the same as SLE. Tr. 608. To evaluate whether a tetracycline caused Ms. Stricker’s health problems, Dr. Rose’s proposal will be analyzed via a structure based upon Althen. See Knudsen v. Sec’y of Health & Hum. Servs., 35 F.3d 543, 549 (Fed. Cir. 1994) (“the standards that apply to a petitioner’s proof of actual causation in fact in off- table cases should be the same as those that apply to the government’s proof of alternative actual causation in fact”); Oliver v. Sec’y of Health & Hum. Servs., No. 10-394V, 2017 WL 747846, at *24-27 (Fed. Cl. Spec. Mstr. Feb. 1, 2017) (following this method of analysis), mot. for rev. denied, 133 Fed. Cl. 341 (2017), aff’d, 900 F.3d 1357 (Fed. Cir. 2018). 1. Prong One – Can Cause The evidence supports a finding that tetracyclines can cause drug-induced lupus. Two potentially overlapping reasons support this finding. First, examples of minocycline use preceding the development of lupus symptoms appear in two articles, El-Hallak and Lawson. While these two articles could be aptly described as case series in that they present sequences of events (and, therefore, carry relatively little value on causation), the Lawson article is different. Some of the subjects in Lawson used minocycline, developed problems, stopped the drug with improvement in problems, restarted the drug, and again experienced health problems. Lawson at 330, Tr. 609. These are examples of challenge-rechallenge, which is strong proof of causation. Capizzano, 440 F.3d at 1322; R.S. v. Sec’y of Health & Hum. Servs., No. 15-1207V, 2021 WL 6502227, at *14 (Fed. Cl. Spec. Mstr. Dec. 15, 2021). 40 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 41 of 48 Second, and perhaps relatedly, Dr. Zizic did not challenge the proposition that tetracyclines can cause drug-induced lupus. See Tr. 177, 284, 349-50. Similarly, Ms. Stricker did not argue that tetracyclines cannot cause drug-induced lupus. See Pet’r’s Posthear’g Br. at 69. Thus, there is sufficient evidence to conclude that tetracyclines can cause drug-induced lupus. See Watts v. Medicis Pharma. Corp., 365 P.3d 944, 947 ¶ 3 (Ariz. 2016). 2. Prong Three – Timing The third Althen prong requires “a showing of a proximate temporal relationship between vaccination and injury.” This point is based upon each vaccination being a discrete one-time to event. However, Ms. Stricker ingested tetracyclines for approximately four years. Tr. 529, 607, 611. According to Dr. Rose, Ms. Stricker’s greater exposure to minocycline made it more likely for her to develop an adverse reaction. Tr. 612. The El-Hallak article presents a series of 27 people with chronic minocycline-induced lupus. The mean duration of minocycline use before the onset of symptoms was 13.0 months ± 10.8 months. El-Hallak at 315, Tr. 534. Thus, the onset of Ms. Stricker’s lupus symptoms is within a medically appropriate time. Again, neither Dr. Zizic nor Ms. Stricker raised any persuasive objection regarding the onset of the lupus problems vis-à-vis her use of minocycline. 3. Prong Two – Logical Sequence The second Althen prong concerns “a logical sequence of cause and effect showing that the vaccination was the reason for the injury.” Here, Ms. Stricker contends that she did not (and does not) have minocycline-induced lupus for various reasons. The first point is that the removal of the drug usually causes symptoms to improve. Contrary to this general principle, after Ms. Stricker stopped taking doxycycline in mid-November, she declined over Thanksgiving and into Christmas. Tr. 228-29 (Dr. Zizic), 529 (Dr. Rose), 608 (Dr. Rose on cross- examination), 614 (same). This reasoning was adopted by a dermatologist who treated Ms. Stricker. Relying upon Lawson, Dr. Breza wrote: “Given that the patient[’]s symptoms have not resolved several years after discontinuation of minocycline, I can be certain that minocycline was not the cause of her connective tissue disorder.” Exhibit 24. However, the El-Hallak article presents examples of people with lupus problems that persisted after they stopped taking minocycline. Tr. 534. Indeed, the title is “Chronic Minocycline-Induced Autoimmunity in Children.” El-Hallak 41 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 42 of 48 at 314. In other words, the patients’ lupus “did not go away.” Tr. 534. These reports counter and undermine the opinion of Dr. Breza. Ms. Stricker’s series of health problems in November and December 2015 reminded Dr. Rose of a case of minocycline-induced lupus in a patient he treated. Tr. 531. Similar features included an acute onset of problems, a vasculitic rash, constitutional symptoms, low ANA, robust sed rate, and minor to moderate liver abnormalities. Id. To Dr. Rose, Ms. Stricker “really looked like a [minocycline- induced lupus] patient.” Tr. 532. Dr. Zizic did not rebut this opinion from Dr. Rose. The key question from Dr. Rose’s perspective is whether Ms. Stricker’s symptoms have resolved in the intervening years. Tr. 533. Dr. Rose identified the following diagnostic possibilities for Ms. Stricker: (1) She had minocycline-induced lupus and still has symptoms of minocycline-induced lupus (2) She had minocycline-induced lupus and now has symptoms of systemic lupus erythematosus, (3) She had minocycline-induced lupus and has stopped having symptoms of minocycline-induced lupus, or (4) She never had minocycline-induced lupus. A person with minocycline-induced lupus can develop “real” lupus. Tr. 630. For example, a patient in El-Hallak’s collection developed antibodies to double- stranded DNA. El-Hallak at 316, Tr. 760. A continuation of symptoms can occur too. For example, the El-Hallak group followed patients with chronic minocycline-induced lupus for as many as 48 months. El-Hallak at 317 (Table 3), Tr. 535-36, 749-50. One patient still had symptoms after 48 months. Whether Ms. Stricker’s lupus symptoms persist is far from clear. She has been taking Plaquenil. Her rheumatologist, Dr. Saba, has not noted any joint involvement Tr. 616, see also Resp’t’s Posthear’g Br. at 23-24 (citing medical records). But, a potentially confounding factor is that Ms. Stricker testified she no longer complains to Dr. Saba about her joint problems. Tr. 128-31.24 24 A lack of complaint would not necessarily preclude Dr. Saba from observing joint swelling. See Tr. 411-12 (Dr. Rose’s description of how rheumatologists examine patients). 42 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 43 of 48 4. Summary If Ms. Stricker had presented persuasive proof on all three Althen prongs and thereby shifted the burden of proof to the Secretary, the Secretary could not succeed in showing on a more likely than not basis that tetracycline induced Ms. Stricker’s lupus. Dr. Rose conceded that SLE is an appropriate diagnosis for Ms. Stricker and minocycline-induced lupus is a less likely alternative. Tr. 529-30. But, on the other hand, to the extent that the presence of potential alternative causes can be considered as part of the second prong of Althen, the evidence regarding tetracycline weakens Ms. Stricker’s case. See Stone v. Sec’y of Health & Hum. Servs., 676 F.3d 1373, 1380 (Fed. Cir. 2012); Doe 11 v. Sec'y of Health & Hum. Servs., 601 F.3d 1349, 1357-58 (Fed. Cir. 2010). Among these two alternatives (HPV vaccine and tetracyclines), tetracycline is a better explanation.25 As discussed above, the evidence shows minocycline can cause a drug-induced lupus at least rarely. In contrast, the evidence does not preponderate in favor of finding that the HPV vaccination can cause SLE. This disparity means that tetracycline is a more likely explanation even if the likelihood of tetracycline is not more likely than not. See Caves, 100 Fed. Cl. 119, 143 n.17 (explaining that the “most likely” cause is not always “more likely than not”). B. HPV Infection In addition to tetracycline, the Secretary suggests Ms. Stricker’s HPV infection could have caused her lupus. The structure for the analysis also follows the Althen prongs. 1. Prong One – Can Cause The parties did not dispute HPV infection can cause SLE. Citing Shi, Dr. Moy proposed this alternative cause in his first report. Exhibit A at 6. Dr. Moy repeated this opinion in his oral testimony. Tr. 678-79. Dr. Zizic also testified that the HPV infection can cause SLE. Tr. 169, 324. Based upon this agreement, further discussion is not needed. 25 Ms. Stricker’s health problems may not have been caused by either the HPV vaccine or tetracyclines because the cause of SLE in the vast majority of cases is unknown. See Gulati & Brunner at 710; see also Bazan v. Sec’y of Health & Hum. Servs., 539 F.3d 1347, 1354 (Fed. Cir. 2008) (“a failure of proof that the vaccine was the cause of the petitioner’s injury suggests that some other cause was responsible”). 43 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 44 of 48 2. Prong Three – Timing Here, the medically acceptable latency between an HPV infection and the development of lupus was unclear and complicated. The Shi article does not present any information about how long people with an HPV infection were infected before manifesting symptoms or signs of lupus. See Shi; see also Tr. 680. One of the problems with determining a medically acceptable latency is that the date of infection is rarely, if ever, known. For example, although Ms. Stricker’s HPV infection was discovered via a Pap smear on August 11, 2015, she was not symptomatic. Exhibit 7 at 83, Tr. 213, 242, 604, 680. Another complication is how the HPV virus acts after transmission. An HPV virus can be dormant. Tr. 681, 684. During this time, the HPV virus hides from the immune system. Tr. 588, 684, 688; see also Godfrey v. Sec’y of Health & Hum. Servs., No. 10-565V, 2014 WL 3058353, at *9 (Fed. Cl. June 11, 2014), mot. for rev. granted in non-relevant part, 2015 WL 4972882 (Fed. Cl. 2015). Then after a period of being dormant, the virus can activate and begin replicating. Tr. 604-06, 684. How any activation and replication might cause SLE was not explained well. Cf. Tr. 686 (suggesting molecular mimicry might be a mechanism). Dr. Moy suggested a person could be infected with HPV virus for two years before developing SLE. Tr. 681, 684. The basis for this opinion was not explained persuasively. The lack of reliable evidence about a medically acceptable interval between HPV infection and onset of lupus is an obstacle to finding that Ms. Stricker’s lupus developed within an appropriate time of her HPV infection. Before she began to display symptoms of lupus around November 1, 2015, she most recently had engaged in sexual activity in August 2014. Tr. 88. The transmission of a sexually communicated virus could have occurred even earlier. Tr. 243. Thus, the latency must have been at least one year. See Tr. 604. Dr. Zizic was skeptical that a latency of more than one year was appropriate. He described this idea as “highly improbable.” Tr. 243. Accordingly, a preponderance of the evidence does not support a finding that Ms. Stricker’s lupus symptoms developed within the medically appropriate time after she contracted the HPV virus. 3. Prong Two – Logical Sequence To complete the topic of the HPV infection as a cause for Ms. Stricker’s lupus, the second Althen prong is briefly reviewed. Again, the reports from treating doctors are entitled to consideration. Here, no treating doctor associated 44 Case 1:18-vv-00056-RAH Document 151 Filed 01/24/24 Page 45 of 48 Ms. Stricker’s lupus with her HPV infection. Tr. 696. This lack of attribution tends to diminish the value of the theory that an HPV infection caused Ms. Stricker’s lupus. 4. Summary Due to the resolution of other issues, resolving whether the HPV virus caused Ms. Stricker’s lupus is not required. However, to the extent a conclusion is needed, the evidence that the HPV virus caused Ms. Stricker’s lupus is slightly stronger than the evidence that the HPV vaccine caused Ms. Stricker’s lupus. Much like the analysis of tetracyclines, the analysis of HPV infection favors a finding that the HPV infection can cause SLE. This finding makes an infectious cause more likely than a vaccine cause. However, the infectious cause itself remains very unlikely due to the uncertainties for timing. VIII. Conclusion The onset of lupus symptoms within approximately six weeks of the HPV vaccination understandably raised a suspicion in the minds of Ms. Stricker and her mother that the HPV vaccine caused Ms. Stricker’s SLE. However, the evidence, considered as a whole, does not preponderate in favor of in finding that Ms. Stricker met her burden of proof. The primary deficiency is that she has failed to present a persuasive theory explaining how an HPV vaccine can cause SLE. In addition, her use of tetracyclines provides a viable alternative explanation of her symptoms. The Clerk's Office is instructed to enter judgment in accord with this decision unless a motion for review is filed. Information about filing a motion for review, including the deadline, can be found in the Vaccine Rules, which are available on the website for the Court of Federal Claims.

SECRETARY OF HEALTH AND HUMAN SERVICES, Respondent. Andrew D. Downing, Downing, Allison & Jorgenson, Phoenix, AZ, for the petitioner. Nina Ren, Torts Branch, Civil Division, U.S. Department of Justice, Washington, D.C., for the respondent. MEMORANDUM OPINION AND ORDER HERTLING, Judge The petitioner, Hayley Stricker, seeks review of a special master’s decision denying her claim under the National Vaccine Injury Compensation Program, 42 U.S.C. § 300aa et seq. The petitioner alleges that the human papillomavirus (“HPV”) vaccine she received on September 29, 2015, caused her to develop systemic lupus erythematosus (“SLE”). The special master denied the petitioner’s entitlement to compensation, and the petitioner seeks review of that decision. The petitioner argues that the special master mistreated evidence and testimony in five respects. She argues that these decisions constitute legal errors because they elevated her burden of proof. The respondent argues that the petitioner is simply attempting to relitigate factual disputes that are within the discretion of the special master to resolve. *Pursuant to Vaccine Rule 18(b), the Court initially filed this opinion under seal and afforded the parties 14 days to notify the court of any information that should be redacted from the opinion for reasons of privilege or confidentiality. The parties did not propose any redactions. Accordingly, this opinion is reissued in its original form for public availability. Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 2 of 25 The petitioner has not identified any legal errors in the special master’s decision. The resolution of the claim depended on the special master’s assessment of the evidence presented by each party’s experts. The special master appropriately considered the evidence and provided a rational basis for his decision, including his resolution of the issues challenged by the petitioner. The petitioner’s challenges effectively amount to an invitation to reconsider the weight given to individual pieces of evidence. Such decisions, however, are within the special master’s purview. Accordingly, the petitioner’s motion for review (ECF 152) is denied. I. FACTUAL BACKGROUND1 A. Petitioner’s Health Prior to Vaccination Haley Stricker was born in 1993. Because her mother suffers from multiple sclerosis (“MS”), the petitioner was at a greater potential risk of developing an autoimmune disease, depending on whether she inherited any MS-associated genes. Her risk for SLE would then depend on whether the genes for SLE and MS are associated with one another.2 The petitioner’s 1 In her motion for review, the petitioner has not raised any objection to the facts set forth in the special master’s entitlement decision, objecting instead to the burden of proof placed upon her and the weight given to the testimony and documentation in evidence. Accordingly, this recitation of the factual background summarizes the special master’s recitation of the background facts. The special master’s internal citations are omitted. For a full recitation of the facts and procedural history, see Stricker v. Sec’y of Health & Hum. Servs, No. 18-56V, 2024 WL 263189, at *1-9 (Fed. Cl. Spec. Mstr. Jan. 2, 2024) (“Entitlement Decision”). 2 MS is “a disease in which there are foci of demyelination throughout the white matter of the central nervous system, sometimes extending into the grey matter; symptoms usually include weakness, incoordination, paresthesias, speech disturbances, and visual complaints. The course of the disease is usually prolonged, so that the term multiple also refers to remissions and relapses that occur over a period of many years. Four types are recognized, based on the course of the disease: relapsing remitting, secondary progressive, primary progressive, and progressive relapsing. The etiology is unknown.” Dorland’s Illustrated Medical Dictionary 1653 (33rd ed. 2020) (hereinafter Dorland’s). The record notes a family history of MS within petitioner’s family. SLE is “a chronic, inflammatory, often febrile multisystemic disorder of connective tissue that proceeds through remissions and relapses; it may be either acute or insidious in onset and is characterized principally by involvement of the skin (cutaneous l. erythematosus), joints, kidneys, and serosal membranes. The etiology is unknown, but it may be a failure of regulatory mechanisms of the autoimmune system, since there are high levels of numerous autoantibodies against nuclear and cytoplasmic cellular components. The condition is marked by a wide variety of abnormalities, including arthritis, arthralgias, nephritis, central nervous system manifestations, pleurisy, pericarditis, leukopenia or thrombocytopenia, hemolytic anemia, an elevated 2 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 3 of 25 health, however, was mostly normal for her first two decades, and she was able to participate in high school sports and yoga without noted issue. In 2010, the petitioner saw a dermatologist, Dr. Thomas Breza, after developing acne. Dr. Breza prescribed minocycline, a type of tetracycline. Minocycline has been known to cause drug-induced lupus.3 The petitioner took this medication from 2010 until 2015. In 2015, the petitioner applied to the dental hygienist program at Broward County College. The dental hygienist program required the petitioner to receive an annual physical exam. On July 27, 2015, the petitioner’s primary care physician, Dr. Janet Robinson, performed the exam and recorded that the petitioner had a healthy diet, exercised, had no fatigue, had normal skin, and showed no signs of joint swelling. Dr. Robinson ordered routine blood work, which returned normal results. These tests did not include an anti-nuclear antibody test, meaning the results did not indicate whether the petitioner was already suffering from lupus at this point. On August 11, 2015, Dr. Breza changed the petitioner’s prescription for minocycline to 100 mg of doxycycline hyclate, another tetracycline. Ten days after her appointment with Dr. Breza, the petitioner went to a different dermatologist, Dr. Green, for a second opinion. Dr. Green changed the petitioner’s prescription to 150mg of Acticlate.4 Around the same date as her August 2015 appointment with Dr. Breza, the petitioner also received her first pap smear from her gynecologist, Dr. Bernstein.5 The pap smear revealed that erythrocyte sedimentation rate, and the presence in the blood of distinctive cells called LE cells.” Dorland’s 1066. 3 The petitioner’s expert witness, Dr. Thomas Zizic, “did not challenge the proposition that tetracyclines can cause drug-induced lupus.” Entitlement Decision, at *26. The special master found “there is sufficient evidence to conclude that tetracyclines can cause drug-induced lupus.” Id. (citing Watts v. Medicis Pharma. Corp., 365 P.3d 944, 947 ¶ 3 (Ariz. 2016)). As noted by the special master, “[d]rug-induced lupus is not the same as SLE.” Entitlement Decision, at *25. Drug-induced lupus is “lupus erythematosus caused by any of various drugs. Hydralazine, procainamide, and minocycline are the most common ones causing systemic lupus, and various other drugs can cause subacute cutaneous lupus. It usually resolves following withdrawal of the offending drug.” Dorland’s 1065. 4 Acticlate appears to be a brand name for doxycycline hyclate. Acticlate, RxList (May 25, 2021), https://www.rxlist.com/acticlate-drug.htm#description. 5 A pap smear or pap test is “an exfoliative cytological staining procedure for detection and diagnosis of various conditions, particularly malignant and premalignant conditions of the female genital tract (cancer of the vagina, cervix, or endometrium). Cells that have been desquamated from the genital epithelium are obtained by smears, fixed and stained, and examined under the 3 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 4 of 25 the petitioner was infected with a strain of HPV. When the petitioner first contracted HPV is unknown. Both the petitioner’s and the respondent’s expert witnesses agreed that “[i]nfections with human papillomaviruses can cause SLE.” Entitlement Decision, at *2. B. Vaccination and Post-Vaccination Onset of Symptoms On September 29, 2015, the petitioner made a return visit to Dr. Bernstein at which she received her first and only dose of the HPV vaccine, Gardasil, to protect her against different strains of HPV. The petitioner received no other vaccines that day. Her claim is based on this vaccine.6 The petitioner’s symptoms began around November 1, 2015, approximately one month after the petitioner received her Gardasil HPV vaccine. Her symptoms included rashes, fatigue, and pain in her ankles, knees, hands, and lower back. The petitioner’s symptoms interfered with her usual activities, including performing the tasks and procedures required in her training to become a dental hygienist. In mid-November 2015, the petitioner began using medical tape to stabilize her wrists so she could perform various techniques in her dental hygiene program. Around Thanksgiving, after searching the internet for possible causes of her symptoms, the petitioner stopped taking her doxycycline medication. On December 4, 2015, the petitioner visited Dr. Robinson complaining of worsened joint pain and rashes. After examination, Dr. Robinson did not observe any joint swelling but ordered a series of lab tests and assessed the petitioner as having “[a]rthralgia of multiple sites.” Id. at *4. The petitioner discussed the HPV vaccine as a potential cause for her symptoms with Dr. Robinson. Dr Robinson’s notes from this appointment express doubt that the vaccine could cause the petitioner’s symptoms because of the timing of the vaccine administration. On December 8, 2015, the results of the lab tests revealed that the petitioner had “high levels of globulin, alkaline phosphatase, C-reactive protein, and erythrocyte sedimentation rate.” Id. Dr. Robinson instructed the petitioner and her mother to bring the results to her dermatologist. Dr. Robinson also referred the petitioner to a rheumatologist. On December 9, 2015, Dr. Green discontinued the petitioner on Acticlate. The petitioner saw Dr. Jihan Saba, a rheumatologist, on December 29, 2015. During that appointment, Dr. Saba recorded the petitioner’s medical history and observed swelling in various microscope for evidence of pathologic changes. The test is also used in detection of human papillomavirus infection, evaluation of endocrine function, and diagnosis of malignancies of other organs, such as the breasts or organs of the respiratory tract and lungs, gastrointestinal tract, or urinary tract.” Dorland’s 1866. 6 Although the petitioner made an appointment for a second dose of the HPV vaccine, the petitioner’s mother canceled the appointment due to a “gut feeling” that the September 29, 2015 dose had caused the petitioner’s decline in health. Entitlement Decision, at *3. 4 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 5 of 25 joints. Dr. Saba diagnosed the petitioner with connective tissue disease. Dr. Saba informed the petitioner and her mother that because the features of this disease frequently change, the diagnosis could change. Dr. Saba also discussed the possibility of drug-induced lupus. Dr. Saba prescribed a low dose of prednisone, which the petitioner discontinued by May 2016. After ordering further lab tests, which returned “some abnormal values,” Dr. Saba prescribed the petitioner hydroxychloroquine and thereafter continued to adjust the petitioner’s medication.7 “The medications improved [the petitioner’s] condition.” Id. at *5. The petitioner also saw another rheumatologist, Dr. Jennifer Savage, on one occasion, but continued seeing Dr. Saba as her rheumatologist. The special master found that the petitioner has experienced no new symptoms since she began her prescription of hydroxychloroquine. In December 2018, after a routine annual exam with Dr. Robinson, lab results identified that the petitioner had a double-stranded DNA antibody, which led Dr. Saba to change the petitioner’s diagnosis from connective tissue disease to SLE. According to the petitioner’s expert, rheumatologist Dr. Thomas Zizic, “antibodies against double-stranded DNA are 99 percent specific for lupus.” Id. at *6. One of the respondent’s experts, rheumatologist Dr. Carlos Rose, “agreed that the diagnosis was most likely systemic lupus erythematosus . . . [h]owever, Dr. Rose stated that even after the detection of anti-double stranded DNA antibodies, drug-induced lupus remains a potential diagnosis for [the petitioner].” Id. As of the petitioner’s January 2022 testimony, she was taking hydroxychloroquine. Dr. Rose testified this drug may be controlling the petitioner’s condition, but the medication interferes with determining whether her lupus is active. Records from Dr. Saba indicate the petitioner has denied having problems with “joint pain, joint swelling, morning stiffness, rashes, [and] photosensitivity. . . . When these records were pointed out to [the petitioner] on cross- examination, she stated that she is frustrated with Dr. Saba” because she “d[id] not write down information” she conveyed to her. Id. The petitioner also testified that “she no longer complains to Dr. Saba about her joint problems.” Id. at *27. In short, the petitioner may have been at a greater risk of developing lupus due to her mother having MS, and she was exposed to “various substances associated with lupus” for years before she received the HPV vaccine on September 29, 2015. Id. at *7. She had also contracted HPV more than one year before her vaccination. She began to develop symptoms at issue by November 1, 2015, and was diagnosed with connective tissue disease until her diagnosis was changed to SLE almost three years later. 7 Hydroxychloroquine is also referred to by its brand name of Plaquenil by the special master. Entitlement Decision, at *5-6; see also Hydroxychloroquine (Plauqenil), American College of Rheumatology (Feb. 2024), https://rheumatology.org/patients/hydroxychloroquine- plaquenil.) 5 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 6 of 25 II. PROCEDURAL HISTORY AND THE SPECIAL MASTER’S DECISION In January 2016, the petitioner submitted a form to the Vaccine Adverse Events Reporting System to report her potential adverse reaction to the HPV vaccine. She filed a petition for compensation under the vaccine program on January 11, 2018. The petitioner alleges that the HPV vaccine caused her to develop SLE. The respondent argues that the petitioner suffers from drug-induced lupus or spontaneously occurring SLE, rather than vaccine-induced SLE. After the petition was filed, the parties submitted affidavits, medical records, expert reports, and medical literature. In support of her petition to the special master, the petitioner submitted letters from Dr. Saba, Dr. Robinson, and Dr. Breza. Additionally, the petitioner submitted two expert reports from Dr. Zizic. The respondent submitted an expert report from Dr. Rose and an expert report from Dr. James Moy, an immunologist. The special master held an entitlement hearing from January 18 to January 21, 2022. The special master heard testimony from the petitioner, one of her friends, her mother, a teacher from her dental hygienist program, and the parties’ three experts. On January 2, 2024, the special master issued a thorough opinion denying the petitioner’s claims. The special master considered whether the petitioner had demonstrated the HPV vaccine caused her to suffer from SLE under the three-prong test established in Althen v. Secretary of Health and Human Services, 418 F.3d 1274, 1278 (Fed. Cir. 2005). Under that test, a petitioner must set forth by preponderant evidence: “(1) a medical theory causally connecting the vaccination and the injury; (2) a logical sequence of cause and effect showing that the vaccination was the reason for the injury; and (3) a showing of a proximate temporal relationship between vaccination and injury.” Id. For the first Althen prong, the special master reviewed scientific studies and reports submitted by both parties and considered the testimony of the parties’ experts about these various reports. First, the special master considered epidemiologic studies and found that the petitioner had not provided credible epidemiologic studies linking the HPV vaccine to an increased incidence of SLE. Entitlement Decision, at *9-17. In reaching that conclusion, the special master analyzed eight epidemiologic studies submitted by the parties and the testimony of the expert witnesses regarding these studies. Id. at *10-16. The special master concluded that the reliable controlled studies did not show that the HPV vaccine increased the incidence of SLE. Id. at *17. The only studies that supported the petitioner’s claim were the Geier and Wang articles. See David A. Geier & Mark R. Geier, A case-control study of quadrivalent human papillomavirus vaccine-associated autoimmune adverse events, 35 Clin. Rheumatol. 1225 (2015); Bin Wang et al., Vaccinations and risk of systemic lupus erythematosus and rheumatoid arthritis: A systematic review and meta-analysis, 16 Autoimmun. Rev. 756 (2017). As to these two studies, the special master found that they relied on “suspect” methodology that rendered them unreliable. Entitlement Decision, at *17. 6 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 7 of 25 The special master next considered studies that examined “how vaccines affect people.” Id. at *17-18. The special master concluded that these studies “do not meaningfully support [the petitioner’s] claim that the HPV vaccine can cause SLE” because they either studied the effects of the flu vaccine, not the HPV vaccine, or did not show that the HPV vaccine worsened symptoms of SLE. Id. at *18. The special master then considered case reports and case series submitted by the petitioner. Id. at *18-20. The special master gave these case reports little weight, relying in part on the implicit conclusion by the Federal Circuit that such reports merit little weight. Id. at *19 (citing Porter v. Sec’y of Health & Human Servs., 663 F.3d 1242, 1253-54 (Fed. Cir. 2012)). Citing a Federal Judicial Center guide, the special master concluded that the case reports were at best anecdotal evidence, insufficient to show association between a vaccine and a condition. Entitlement Decision, at *18-19 (citing David H. Kaye and David A. Freedman, Reference Manual on Scientific Evidence, Reference Guide on Statistics, at 217-18 & n.14 (3d ed. 2011)). Finally, the special master credited the testimony of Dr. Rose and Dr. Moy that confirmed “case reports are generally not effective ways to show causation” and that there were specific problems with the petitioner’s proffered case reports. Id. at *20. Lastly, the special master reviewed the petitioner’s proposed medical theory of molecular mimicry.8 Id. at *20-22. The special master concluded that the petitioner had failed to meet her burden of showing by preponderant evidence that molecular mimicry could serve as a theory by which the HPV vaccine can cause SLE. Id. at *22. After concluding that the petitioner had not satisfied the first Althen prong, and before considering the second Althen prong, the special master considered the third Althen prong. He held that the petitioner “could have met her burden on prong three” if her theory of molecular mimicry had been proven under the first Althen prong. Id. at *23. The special master next considered the second Althen prong. The evidence to support the petitioner’s claim on this prong was Dr. Zizic’s opinion and letters from two of the petitioner’s treating physicians. Id. at *23-25. The special master concluded that the petitioner had not presented sufficient evidence to support a logical sequence of cause and effect between the vaccination and the injury. First, the special master considered Dr. Zizic’s evidence and concluded that, although Dr. Zizic established that the petitioner’s injuries manifested in a timely manner, the evidence did not sufficiently establish a causal relationship. Id. at *24. Next, the special master considered the letters from Dr. Saba and Dr. Robinson and found them insufficient to meet the petitioner’s burden of proof. Dr. Saba’s letter did not assist the petitioner because she noted only that it was 8 The special master also addressed the theory of Granzyme B, which the petitioner relied on early in the case but did not pursue during the entitlement hearing. Entitlement Decision, at *22- 23. The petitioner has not appealed the rejection of this theory, and her only theory on appeal is based on molecular mimicry. (ECC 155 (not mentioning Granzyme B).) 7 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 8 of 25 “very possible” that the vaccine had caused the petitioner’s injury, and this statement did not satisfy the burden to establish a logical sequence. Id. (citing Paterek v. Sec’y of Health & Hum. Servs., 527 F. App’x 875, 883 (Fed. Cir. 2013); Austin v. Sec’y of Health & Hum. Servs., 141 Fed. Cl. 268, 280 (2018); Doe v. Sec’y of Health & Hum. Servs., 19 Cl. Ct. 439, 450 (1990)). Based on the temporal sequence, Dr. Robinson opined that “‘it does seem likely that [the petitioner’s] autoimmune disease was triggered by the vaccine.’” Entitlement Decision, at * 24 (quoting Ex. 23). The special master concluded that this opinion by one of the petitioner’s treating physicians “may have been sufficient” to meet the petitioner’s burden under the second Althen prong. Id. at *25. Because the petitioner failed both to satisfy her burden under the first Althen prong and to rule out alternative causes, however, Dr. Robinson’s letter was insufficient to meet the petitioner’s burden under the second Althen prong. Id. (citing Langland v. Sec’y of Health & Hum. Servs., 109 Fed. Cl. 421, 438 (2013)). With respect to potential alternative causes of the petitioner’s injuries, the special master found that “tetracycline is a more likely explanation” of the petitioner’s lupus, “even if the likelihood of tetracycline is not more likely than not.” Entitlement Decision, at *27. The special master also found that “evidence that the HPV virus caused [the petitioner’s] lupus is slightly stronger than the evidence that the HPV vaccine caused [her] lupus,” because some evidence suggests that the HPV virus can cause lupus, but “the infectious cause itself remains very unlikely due to the uncertainties for timing.” Id. at *29. On February 1, 2024, the petitioner filed a timely motion for review of the special master’s decision. (ECF 152; ECF 155.) The respondent filed a response on March 1, 2024. (ECF 157.) On March 8, 2024, the petitioner filed a reply after receiving permission from the Court. (ECF 159; ECF 160.) III. JURISDICTION AND STANDARD OF REVIEW The Court of Federal Claims has jurisdiction to review decisions made by special masters under the Vaccine Program. 42 U.S.C. § 300aa-12(e). Under this jurisdiction, the court may “set aside any findings of fact or conclusion of law of the special master found to be arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law and issue its own findings of fact and conclusions of law.” 42 U.S.C. § 300aa-12(e)(2)(B); see also Rule 27(b), Appendix B to the Rules of the Court of Federal Claims (“RCFC”). The standard of review applied to a decision by a special master is “the most deferential possible.” Munn v. Sec’y of Dep’t of Health & Hum, Servs., 970 F.2d 863, 870 (Fed. Cir. 1992). A court “may set aside the decision of a special master only if the special master’s fact findings are arbitrary and capricious, its legal conclusions are not in accordance with law, or its discretionary rulings are an abuse of discretion.” Turner v. Sec’y of Health & Hum. Servs., 268 F.3d 1334, 1337 (Fed. Cir. 2001). A court “owes [the] findings and conclusions by the special master great deference—no change may be made absent first a determination that the special master was ‘arbitrary and capricious.’” Munn, 970 F.2d at 870. Under this standard the “court does not reweigh the factual evidence or assess whether the special master correctly evaluated the evidence.” Porter, 663 F.3d at 1254. It is not the court’s role to “second guess the 8 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 9 of 25 Special Master’s fact-intensive conclusions,” especially when the “‘medical evidence of causation is in dispute.’” Id. at 1249 (quoting Hodges v. Sec’y of Health & Human Servs., 9 F.3d 958, 961 (Fed. Cir. 1993)). A petitioner can satisfy the Althen standards “‘by medical records or by medical opinion.’” Campbell v. Sec’y of Health & Hum. Servs., 97 Fed. Cl. 650, 659 (2011) (quoting 42 U.S.C. § 300aa–13(a)(1)). A special master may not impermissibly raise the petitioner’s burden by requiring “epidemiologic studies or general acceptance in the scientific or medical communities.” Andreu ex rel. Andreu v. Sec’y of Dep’t of Health & Hum. Servs., 569 F.3d 1367, 1378 (Fed. Cir. 2009) (cleaned up). Nevertheless, special masters are “entitled to require some indicia of reliability to support the assertion of the expert witness.” Moberly ex rel. Moberly v. Sec’y of Health & Hum. Servs., 592 F.3d 1315, 1324 (Fed. Cir. 2010). When the parties submit epidemiological evidence or medical literature, “the special master can consider it in reaching an informed judgment as to whether a particular vaccination likely caused a particular injury.” Andreu, 569 F.3d at 1379. IV. DISCUSSION In her motion for review, the petitioner argues that the special master made five legal errors that are grounds for reversal. Organizing these by Althen prong, under the first prong she argues that (1) the special master considered flawed epidemiological studies that denied causation; (2) the special master discredited the studies and literature that supported causation; and (3) the special master raised the required amount of evidence for the petitioner to demonstrate molecular mimicry. The petitioner alleges that these are all legal errors because they had the effect of improperly raising her burden of proof. (ECF 152 at 2.) Under the second Althen prong, the petitioner argues that (1) the special master improperly discredited the evidence from the petitioner’s treating physician and testimony from her rheumatologist, again raising her burden of proof; and (2) the special master’s discounting of the petitioner’s treating physician on alternative causation was legal error. (Id. at 1-2.) The respondent argues that the special master acted appropriately as the finder of fact, and that the petitioner’s arguments are simply attempts to relitigate these findings. (ECF 157 at 7.) The petitioner appears to advance arguments premised on the view that the special master’s fundamental error is that he did not shift the burden to the respondent once she met her burden of proof by establishing a prima facie case. (ECF 155 at 16-17.) “Drawing on the general torts context, if this case were in district court, it never would have been dismissed on a motion for summary judgment. This equates with what the Special Master has done here.” (Id. (emphasis in original).) The petitioner acknowledges that “[i]f the Special Master wants to weigh expert opinions on both sides and render a decision on which causal opinions are more reliable, that is within his purview. But to say that the Petitioner in this case - with these facts - failed to meet her burden of proof in the Vaccine Program is not in accordance with the law.” (Id. at 16.) In short, the petitioner claims that because she presented prima facie evidence, she met her burden of proof, shifting the burden to the respondent to counter her evidence. 9 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 10 of 25 The petitioner’s view of her burden is incorrect. As she acknowledges (id. at 19, 22), her burden is to prove all elements by preponderant evidence, not merely to show a “plausible” or “possible” causal link between a vaccine and a condition. W.C. v. Sec’y of Health & Hum. Servs., 704 F.3d 1352, 1356 (Fed. Cir. 2013). Federal Circuit caselaw makes clear that a special master may view competing evidence, including evidence of other possible sources of injury “not only to the ‘factors unrelated’ defense, but also to whether a prima facie showing has been made that the vaccine was a substantial factor in causing the injury in question.” Stone v. Sec’y of Health & Hum. Servs., 676 F.3d 1373, 1379 (Fed. Cir. 2012). “Although a Vaccine Act claimant is not required to present proof of causation to the level of scientific certainty, the special master is entitled to require some indicia of reliability to support the assertion of the expert witness.” Moberly, 592 F.3d at 1324. “The determination of whether a proffered theory of causation is ‘reputable’ may ‘involve [an] assessment of the relevant scientific data.’” Hazlehurst ex rel. Hazlehurst v. Sec’y of Health & Human Servs., 88 Fed. Cl. 473, 479 (2009) (quoting Andreu, 569 F.3d at 1380). “Expert opinion testimony is just opinion, and the fact-finder may weigh and assess that opinion in coming to her own conclusions.” Sword v. United States, 44 Fed. Cl. 183, 188 (1999). “Finders of fact are entitled—indeed, expected—to make determinations as to the reliability of the evidence presented to them and, if appropriate, as to the credibility of the persons presenting that evidence.” Moberly, 592 F.3d at 1326 (approving of the special master making reliability and credibility determinations in a case where the special master found the petitioner had not shown a vaccine caused a petitioner’s injury). Only once a petitioner has presented reliable, preponderant evidence that meets her burden under Althen does the burden shift to the respondent to show by preponderant evidence that some other cause is responsible for a petitioner’s condition. See Althen, 418 F.3d at 1278 (cleaned up) (“If [the petitioner] satisfies this burden, she is entitled to recover unless the government shows, also by a preponderance of evidence, that the injury was in fact caused by factors unrelated to the vaccine.”). Although the petitioner attempts to frame her argument as one alleging that the special master committed errors of law, that argument is rejected. The petitioner’s argument, seeking to sidestep the deferential review due to a special master’s factual findings, would effectively collapse the burden-shifting approach to proving non-Table vaccine claims and negate any role for the special master at the initial stage. According to the petitioner, well-pleaded allegations supported by a facially plausible theory of causation would be enough to shift the burden to the respondent. That approach is at odds with the Federal Circuit’s outline of the process. See id. The application of general legal principles cannot substitute for gaps in the evidence a petitioner needs to prove causation in a particular case. The petitioner’s assigned errors reflect challenges to the special master’s evaluation of the evidence and the inferences drawn from the evidence. These arguments are reviewed under the highly deferential arbitrary-and-capricious standard. Turner, 268 F.3d at 1337. The petitioner’s arguments that the special master erred by critically assessing and rejecting her evidence do not show that the special master’s decisions on each alleged error and on the evidence in total were arbitrary and capricious. Instead, the special master’s decision 10 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 11 of 25 reflects a careful and considered analysis of each of the petitioner’s arguments presented on her motion for review. A. The First Althen Prong Under the first Althen prong, the special master considered various studies and articles addressing the evidence of a statistical connection between the HPV vaccine and lupus, as well as evidence on the petitioner’s proffered theory of the mechanism of causation: molecular mimicry. After reviewing the evidence and assessing it for reliability, the special master found that the evidence did not show that it was more likely than not that the HPV vaccine can cause lupus. The petitioner objects to the special master’s assessment of specific pieces of evidence that formed the basis of his conclusion. 1. Scientific Studies The special master found that the petitioner had not shown that the HPV vaccine can cause SLE. In reaching this conclusion, the special master reviewed eight epidemiologic studies. The special master found that four of the studies, Chao, Arnheim-Dahlström, Miranda, and Liu “did not detect an increased incidence of SLE following HPV vaccination,” notwithstanding the petitioner’s attempts to undermine these studies. Entitlement Decision, at *17 (citing Chao et al., Surveillance of autoimmune conditions following routine use of quadrivalent human papillomavirus vaccine, 271 J. Intern. Med. 193 (2012); Lisen Arnheim-Dahlström et al., Autoimmune, neurological, and venous thromboembolic adverse events after immunisation of adolescent girls with quadrivalent human papillomavirus vaccine in Denmark and Sweden: cohort study, 347 BMJ 15906 (2013); Sara Miranda et al., Human papillomavirus vaccination and risk of autoimmune diseases: A large cohort study of over 2 million young girls in France, 35 Vaccine 4761 (2017); Erin Y. Liu, Quadrivalent human papillomavirus vaccination in girls and the risk of autoimmune disorders: the Ontario Grade 8 HPV Vaccine Cohort Study, 190 CMAJ E648 (2018)). The special master noted that a fifth study, Grimaldi, while involving a smaller sample, also showed that “HPV vaccination was not statistically associated with SLE.” Id. (citing Lamiae Grimaldi-Bensouda et al., Risk of autoimmune diseases and human papillomavirus (HPV) vaccines: Six years of case-referent surveillance, 79 J. Autoimmun. 84 (2017)). The special master found that three of the studies, Geier, Wang, and Jorgensen were not reliable. Id. (citing Geier, supra; Wang, supra; Lars Jorgensen et al., Benefits and harms of the human papillomavirus (HPV) vaccines: systematic review with meta-analyses of trial data from clinical study reports, 9 Syst. Rev. 43 (2020)). The special master rejected reliance on Geier due to suspect methodology and the authors’ past reliability issues. Because Wang’s meta-analysis of other studies was skewed by considering Geier, the special master found Wang unreliable. Id. Finally, the special master declined to rely on Jorgensen because, while it suggested that HPV vaccines can cause some conditions, lupus was not one of the conditions the study examined. Id. The special master also reviewed three studies that “concern[ ] how vaccines affect people.” Id. The special master found that two of these articles, Abu-Shakra and Toplak, were not helpful to the petitioner because they studied the effects of the flu vaccine rather than the 11 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 12 of 25 HPV vaccine. Id. at *17-18 (citing M. Abu-Shakra et al., Influenza Virus Vaccination of Patients with SLE: Effects on Generation of Autoantibodies, 21 Clin. Rheumatol. 361 (2002); N. Toplak & T. Avclin, Vaccination of healthy subjects and autoantibodies: from mice through dogs to humans, 18 Lupus 1186 (2009)). As for the third article, Dhar, it showed that the administration of the HPV vaccine to participants with SLE did not result in a worsening of their symptoms, and therefore was at least indirect evidence against the petitioner’s causation theory. Id. at *18 (citing J. Patricia Dhar et al., The safety and immunogenicity of Quadrivalent HPV (qHPV) vaccine in systemic lupus erythematosus, 9 Vaccine 2642 (2017)). Finally, the special master considered but rejected relying on case reports and case series, based on precedent showing that these types of evidence merit little weight. Id. at *18-19. The petitioner does not challenge this treatment. The petitioner raises three challenges to the special master’s evaluation of these studies in deciding whether the petitioner met her burden under the first Althen prong. First, the petitioner argues that the special master should have not relied on the studies that tended to show no connection between the HPV vaccine and lupus, based on Dr. Zizic’s criticisms of those studies. Second, she argues that the special master improperly discounted Geier, Wang, and Jorgensen. Third, she argues that the special master required the petitioner to submit elevated proof to demonstrate molecular mimicry. (ECF 155 at 22-41.) a. Petitioner’s Objection to the Special Master Considering “Flawed” Studies i. Chao The petitioner challenges the special master’s reliance on Chao, a study conducted by Merck, the manufacturer of the Gardasil HPV vaccine, in cooperation with Kaiser Permanente. The special master noted this fact in his decision, writing “Merck ‘had significant input into the study design and analytic plan, all pre-specified in a protocol that was approved by [Food and Drug Administration.]’” Entitlement Decision, at *10 (quoting Chao, supra, at 202). He went on to note that while “Merck also ‘took part in the review of analysis and drafting and revising the manuscript[,]’ [h]owever, ‘Kaiser Permanente authors held final decision power about all editorial suggestions.’” Id. (quoting Chao, supra, at 202) (internal citations omitted). Chao showed an incident rate ratio of autoimmune disease between vaccinated and unvaccinated populations that was close to 1.0. The special master addressed Dr. Zizic’s criticisms of Chao, ultimately rejecting them. Id. at 11. The special master cited this study to support his finding that there was no evidence that the HPV vaccine could cause lupus, although he acknowledged that the petitioner “can legitimately point to a non-standard technique for filling in missing data, which was not really missing. Even if Chao is excluded, however, the Arnheim-Dahlström, Miranda, and Liu articles still indicate that researchers have not detected an increased incidence.” Id. at *17. The petitioner relies on Dr. Zizic’s testimony regarding Chao to challenge the special master’s reliance on it on two grounds. First, the petitioner argues the study was unreliable 12 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 13 of 25 because of the influence Merck had on the study. (ECF 155 at 24-25, 28.) Second, the petitioner argues that the study improperly imputed data about the incidence of autoimmune diseases in the unvaccinated when the study’s authors could have examined the actual data about the unvaccinated. (Id. at 25-29.) This failure by the authors was, as Dr. Zizic put it, “‘a statistical manipulation fraudulently done to deceive the true results of this study.’” (Id. at 28-29 (quoting Tr. 734).)9 The special master considered and appropriately rejected the petitioner’s arguments. Regarding the potential conflict of interest due to Merck’s involvement in the study, the special master noted that “‘Kaiser Permanente authors held final decision power about all editorial suggestions.’” Entitlement Decision, at *10 (quoting Chao, supra, at 202). The special master concluded that the final control Kaiser Permanente scientists had over the final product was sufficient to guard against Merck’s self-interest in a favorable study. The petitioner has not shown any reason to conclude that the special master’s reliance on the study despite a potential conflict of interest was arbitrary or unreasonable. To the extent the petitioner argues that the authors intentionally manipulated the data, the special master noted that Dr. Zizic was not persuasive in showing the data were manipulated. Id. at *11-12. The petitioner has not identified any basis to show that the data was, in fact, manipulated. Instead, she offers insinuations and draws a different inference than did the special master. That is insufficient to overturn a special master’s reasoned decision. Although Merck may have had the opportunity to try to manipulate the data, the special master’s conclusion that the study was not manipulated is reasonable, given Kaiser Permanente’s control over the study. As to the criticism of the study’s use of imputed data, the special master specifically considered Dr. Zizic’s criticism and found it “unpersuasive.” Id. at *11. The special master determined that Dr. Zizic had not shown that the imputation caused any manipulation of the data. The special master did acknowledge flaws in the study. He noted that “the evidence regarding methodology is mixed,” and that the petitioner “can legitimately point to a non-standard technique for filling in missing data, which was not really missing.” Id. at *17. He therefore noted that “even if Chao were excluded, the Arnheim-Dahlström, Miranda, and Liu articles still indicate that researchers have not detected an increased incidence.” Id. The record reflects that the special master considered Dr. Zizic’s criticisms of Chao and determined that these criticisms did not outweigh the study’s conclusion showing no connection between the HPV vaccine and SLE. The petitioner fails to show that the special master’s logic is so unsound as to be arbitrary and capricious. Instead, he acknowledged the article’s flaws, recognized potential limitations, and found the article ultimately reliable. He implicitly concluded that, even though it was sub-optimal to use imputed data over available data, that weakness did not produce an inherently flawed conclusion. Id. at *11. 9 Citations to “Tr.” refers to the transcript of the testimony taken at the entitlement hearing, available at ECF 125, ECF 126, ECF 133, and ECF 134. 13 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 14 of 25 Importantly, he also noted that even if he had declined to rely on Chao, he would have reached the same conclusion based on the evidence in Arnheim-Dahlström, Miranda, and Liu. Id. at *17. Thus, even if the special master’s decision to rely on Chao was mistaken, it was harmless error because the remaining evidence would otherwise have supported the special master’s conclusion. See A.Y. by J.Y. v. Sec’y of Health & Hum. Servs., 152 Fed. Cl. 588, 599 (2021) (quoting Hines on Behalf of Sevier v. Sec’y of Dep’t of Health & Hum. Servs., 940 F.2d 1518, 1526 (Fed. Cir. 1991); citing Doe v. Sec’y of Health & Human Servs., 601 F.3d 1349, 1356 n.2 (Fed. Cir. 2010)) (“When ‘the special master’s decision was based on a number of factors and [petitioner] has not shown that the reliance on the [information] . . . was likely critical to the result,’ such a mistake constitutes ‘harmless error’ and does not justify reversing the special master’s decision.”). ii. Arnheim-Dahlström, Miranda, and Liu The special master relied on Arnheim-Dahlström, Miranda, and Liu to support his conclusion that the HPV vaccine cannot cause SLE. The petitioner reasserts arguments, rejected by the special master, made by Dr. Zizic criticizing each of these studies. Concerning Arnheim-Dahlström, Dr. Zizic claimed that it was not helpful for examining lupus-related adverse outcomes from the HPV vaccine. This study was based on data collected during a six-month period from hospital patients in Sweden and Denmark. Dr. Zizic criticized it because fewer “‘than 5 percent in the last 10 years of patients with lupus are hospitalized during any one year period, much less [a] 180 day period.’” (ECF 155 at 30 (quoting Tr. 383).) The special master specifically considered and rejected this criticism. Instead, he credited Dr. Rose’s testimony that “pediatric rheumatologists in Europe see their patients in hospitals.” Entitlement Decision, at *12. The special master’s reliance on the study was reasonable because Dr. Rose’s testimony directly undercut the basis for Dr. Zizic’s critique. The petitioner has not supplied any citation to the record to show that the special master erred in relying on Dr. Rose’s rebuttal of Dr. Zizic. Concerning Miranda, Dr. Zizic claimed that it was unreliable because it relied on searches of French computer databases to identify teenage girls with autoimmune diseases, including SLE. The problem with this approach, according to Dr. Zizic, was the study’s reliance on two ICD-10 codes, which would capture patients with both SLE and subcutaneous lupus. According to Dr. Zizic, the use of ICD-10 codes diluted the data on SLE because subcutaneous lupus patients are never hospitalized. He also asserted that the study’s methodology would not “‘pick up the vast majority of lupus cases that would not be hospitalized in this population.’” (ECF 155 at 31 (quoting Tr. 724).) The special master again specifically addressed Dr. Zizic’s criticisms of the study’s methodology. He noted that the study captured data from other records, specifically long-term illness reimbursement records. The respondent’s experts, Dr. Rose and Dr. Moy, explained that because SLE is a chronic disease, these records would capture patients suffering from SLE, and Dr. Zizic did not refute this analysis. Entitlement Decision, at *15. Further, the special master noted that even if there was an undercounting of lupus cases, the undercounting would have been the same for vaccinated and unvaccinated populations, something Dr. Zizic conceded. Id. 14 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 15 of 25 The special master explained his basis for rejecting Dr. Zizic’s criticisms of Miranda. His reasons were grounded in the testimony, effectively unrefuted, of the respondent’s experts. The petitioner has failed to point to any evidence the special master overlooked or otherwise failed to consider. She simply disagrees with his conclusion, but mere disagreement is not an adequate basis for rejecting a special master’s reasoned conclusion. Finally, concerning Liu, the petitioner’s criticism in full is as follows: Dr. Zizic states “[s]ixty days following vaccination is not a sufficient period of time to diagnose SLE for the reasons previously discussed above.” Ex. 75, p. 5. Dr. Zizic also criticized the lumping of disorders into one category, and stated “[i]t does not make scientific sense to combine systemic lupus erythematosus with systemic sclerosis for example. The etiopathogenesis of these disorders are likely to be so disparate that it does nothing but confuse the analysis.” Id. at 6. Petitioner effectively rebutted the epidemiological studies. This is not asking the Court to re-weigh the epidemiological evidence. It is to show [the] Special Master’s [ ] arbitrary and capricious findings that somehow this epidemiological evidence carries the day, when it is completely flawed and not a requirement for Petitioner to prevail. (ECF 155 at 32.) On the first point, Dr. Rose testified that the 60-day window “more likely conforms to what is biologically plausible,” and that, in any case, “the authors [of the study] exp[a]nded the window in a sensitivity analysis to 180 days.” Entitlement Decision, at *16. As for the second point, the special master concluded that “Dr. Rose persuasively explained why including other diseases with SLE would not affect the analysis.” Id. On both issues, the special master had testimony from Dr. Rose that conflicted with Dr. Zizic’s; it was up to the special master, as the fact finder, to choose between the conflicting testimony. The petitioner fails to explain why the special master’s decision to find Dr. Rose’s testimony more credible was so misplaced as to make that decision arbitrary and capricious; she instead simply points to conflicting evidence from Dr. Zizic and claims it is sufficient to rebut the epidemiological evidence without re-weighing it. (ECF 155 at 32.) The petitioner is mistaken; the special master had an adequate evidentiary basis for his decision, and any second- guessing on appeal of this point would very much require re-weighing the available evidence. b. Petitioner’s Objection to the Special Master Discrediting Studies that Support Causation The special master considered but found unreliable three epidemiologic studies: Geier, Wang, and Jorgensen. These studies, the petitioner contended, showed a causal link between the HPV vaccine and SLE. Because Geier and Wang are interrelated, they are considered together. 15 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 16 of 25 The special master also found unreliable two other studies, Abu-Shakra and Toplak, that examined the effects of flu vaccinations both on persons with SLE and on healthy people. i. Geier and Wang Geier used the Vaccine Adverse Event Reporting System (“VAERS”) database to evaluate the potential for the HPV vaccine to induce serious autoimmune events, including SLE. Entitlement Decision, at *13. Dr. Zizic testified that there was nothing wrong with the methodology employed; Dr. Rose testified that the study was not reliable due to its definition of exposure and its calculations of controls versus cases. The special master found Geier unreliable because it relied on the VAERS database as a data source; the VAERS database has consistently been rejected as a source of reliable data. Id. (citing Tompkins v. Sec’y of Health & Hum. Servs., 117 Fed. Cl. 713, 721 (2014); Analla v. Sec’y of Health & Hum. Servs., 70 Fed. Cl. 552, 558 (2006); Doe v. Ortho-Clinical Diagnostics, Inc., 440 F. Supp. 2d 465, 475-76 (M.D.N.C. 2006)). The special master also noted evidence that the Geiers “are not trustworthy,” that their “work is problematic,” and that they “have been repeatedly discredited in the Vaccine Program.” Id. at *13 & n.12. The special master also found Wang unreliable because of its reliance on Geier. Wang is a meta-analysis of other observational studies, including five studies involving the HPV vaccine and SLE. Id. at *14. One of those studies was a 2017 Geier study, which is different from the Geier (2015) article, previously discussed, published in 2015. The difference, for the purpose of the special master’s analysis is minimal. As the special master noted, the “Wang group excluded the Geier (2015) article because its data was ‘overlapping.’” Id. (quoting Wang, supra, at 758). The special master found the inclusion of the 2017 Geier article “questionable and significant” because the Geiers’ methodology “is not reliable” and because out “[o]f the five relevant studies, the Geier study found the highest relative risk” and was the “only article in which the 95% confidence interval did not cross [a] 1.0” rate ratio. Id. In other words, the already-suspect Geier study was an outlier and was based on the same data as the Geier (2015) article. The special master, relying on Dr. Rose’s testimony, also questioned the legitimacy of the peer- review process for Wang; the article was accepted for publication only four days after submission and published less than two weeks later. Id. For these reasons, the special master therefore found that “the Wang article merits little, if any, weight.” Id. The petitioner objects to this treatment of Wang. She argues that the special master “does not articulate anything in the Geier study at issue that is unsound,” and therefore his rejection of Wang based on Geier is likewise unsound. (ECF 155 at 33.) Dr. Zizic relied on Wang in testifying that it showed a significantly increased risk of SLE from the HPV vaccine. (Id. at 34.) The petitioner has not identified any error in the special master’s analysis. The special master explained that the Geier (2015) article was unreliable because both its methodology was questionable and its authors were not trustworthy. Although the special master in his decision specifically addressed and rejected only the Geier (2015) article, which the petitioner had offered for evidence, he also considered the Geier (2017) article in the context of reviewing Wang. The authors of Wang had considered the data reflected in the Geier (2017) article to overlap with the data in the Geier (2015) article. The special master concluded therefore that the weaknesses he 16 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 17 of 25 had identified in Geier (2015) were also reflected in the Geier (2017) article. Entitlement Decision, at *14. Once the Geier (2017) article was excluded from Wang, the remaining studies Wang cited failed to show a 95-percent confidence interval that did not cross a 1.0 rate ratio. Id. The petitioner has provided no reason to conclude that the special master’s decision finding Wang unpersuasive after excluding the Geier (2017) article was arbitrary and capricious; rather, the special master appropriately examined Wang’s methodology and found it unreliable. ii. Jorgensen The special master next addressed Jorgensen, submitted by the petitioner. Jorgensen was based on data from “79% of clinical study reports, which underlie the report of HPV vaccine safety that the vaccine manufacturer submitted to European regulatory agencies.” Id. at *16. According to the special master, the authors conducted a meta-analysis of the results focused on various outcomes, but not on lupus. Although the authors suggested that there was a high risk of bias in manufacturer safety studies and a possibility that the HPV vaccine caused greater harm for some conditions than previously reported, these conditions did not include lupus. The special master submitted for the record an article responding to Jorgensen. Id. (citing Hilda Bastian, What the systematic review of HPV vaccine clinical study reports does, and does not, reveal: commentary on Jørgensen et al., 9 Syst. Rev. 41 (2020)). Bastian argued that Jorgensen “‘demonstrates the risk of relying too much on [clinical study reports].’” Id. (quoting Bastian, supra, at 41). Ultimately, the special master found Jorgensen unhelpful because it “did not provide any information helpful to determining whether HPV vaccines can cause SLE.” Id. The petitioner objects to the special master sua sponte submitting Bastian and relying on it. The petitioner cited Dr. Zizic’s testimony about the importance of Jorgensen which, Dr. Zizic claimed “‘should allow better detection of some of the adverse events or the harms.’” (ECF 155 at 35 (quoting Tr. 246).) The petitioner, however, does not identify any testimony that explains how or why Jorgensen shows a connection between the HPV vaccine and SLE. The special master’s decision to reject Jorgensen was not based on Bastian’s criticism of Jorgensen. Even assuming that the special master’s consideration of Bastian was improper, his rejection of Jorgensen as useful to and supportive of the petitioner’s claims was unaffected by the asserted error. Thus, even if the inclusion of Bastian was error, it was harmless error and does not provide a basis for finding the special master’s rejection of Jorgensen to have been arbitrary and capricious. See A.Y. by J.Y., 152 Fed. Cl. at 599. iii. Abu-Shakra and Toplak The special master next examined “stud[ies] [that] concern[ ] how vaccines affect people.” Entitlement Decision, at *17. To support her claim, the petitioner submitted two articles, Abu-Shakra and Toplak. See Abu-Shakra, supra; Toplak, supra. Abu-Shakra indicated that women with SLE who were given a flu vaccine had increased antibodies, including antibodies associated with lupus, six and 12 weeks after vaccination. Dr. Zizic claimed that the article indicated that flu vaccines were not safe because the resulting antibodies would cause damage to the recipient. Entitlement Decision, at *17. He further testified that the vaccine recipients in Abu-Shakra “did not have adverse consequences because 17 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 18 of 25 . . . they were being treated for lupus.” Id. The special master noted that “[w]hen asked about the people in Abu-Shakra receiving a flu vaccine versus the HPV vaccination that [the petitioner] received, Dr. Zizic’s response was the HPV vaccine is the “‘same difference.’” Id. (quoting Tr. 194). Dr. Zizic’s testimony conflicted with the conclusions of Abu-Shakra, which found that “‘[p]atients with SLE should be encouraged to receive the influenza vaccine.’” Id. (quoting Abu- Shakra, supra, at 372). Dr. Rose also testified in response to Dr. Zizic that “fluctuations in antibodies [on which Dr. Zizic had relied] do not mean much. Rheumatologists care about only a few antibodies that might correlate to disease severity.” Id. Toplak found that some “‘apparently healthy adults’” who were given the flu vaccine “experienced an increase in antibodies.” Id. at *18 (quoting Toplak, supra, at 135). The size of the increase was not described, and the study did not include controls. Dr. Rose testified that Toplak did not “show anything of significance,” while the special master noted “Dr. Zizic barely mentioned Toplak in his oral testimony.” Id. The special master also considered Dhar, a report of a clinical trial, submitted by the respondent. Id. (citing Dhar, supra). Dhar showed that women with mild to moderate SLE who received the HPV vaccine did not show a flare of their symptoms. Id. The special master concluded that Abu-Shakra and Toplak “do not meaningfully support [the petitioner’s] claim that the HPV vaccine can cause SLE,” because they involved the flu vaccine, not the HPV vaccine. Id. He also determined that none of the studies showed any worsening of the condition of vaccine recipients diagnosed with SLE. Id. The petitioner objects to the special master’s conclusion that Abu-Shakra and Toplak do not meaningfully support her contention that the HPV vaccine can cause lupus. The petitioner’s objection appears to be based on three points. First, these articles showed an increase in antibody and autoantibody production from vaccines. Second, Toplak explained that molecular mimicry could be “‘[p]ossible mechanisms for this autoimmune phenomenon,’” due to an increased level of autoantibodies observed in the subjects who received the flu vaccine. (ECF 155 at 37 (quoting Toplak, supra, at 1, 4).) Third, Abu-Shakra noted that “‘[i]nfectious agents and various vaccines may act as a trigger mechanism for the induction of autoimmunity and the development of SLE.’” (Id. (quoting Abu-Shakra, supra, at 1).) As the special master noted, Abu-Shakra and Toplak both examined the effects of the flu vaccine, not the HPV vaccine. The petitioner does not explain why the special master’s reliance on this difference is wrong and points to no evidence the special master overlooked in relying on this difference in declining to rely on these studies. In the absence of evidence or a sound explanation for equating the effects of the flu and HPV vaccines, it is not arbitrary and capricious for the special master to treat the effects of different vaccines differently and to limit the Abu- Shakra and Toplak studies’ findings to their subject matter: the flu vaccine. Without a showing that the flu and HPV vaccines produce similar antibody reactions among vaccine recipients, the petitioner cannot show that the special master’s decision was arbitrary and capricious. 18 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 19 of 25 The special master’s consideration of the studies on causation was rational. The petitioner’s arguments at best show some conflicting evidence that the special master appropriately analyzed for reliability. The petitioner has not shown that the special master raised her burden of proof. The petitioner’s arguments amount to little more than claims that the special master erred by crediting the evidence showing no significant connection between the HPV vaccine and lupus and not crediting the contrary evidence. The special master explained his rationale for his acceptance or rejection of each piece of evidence. The petitioner has not shown those explanations to be arbitrary and capricious. 2. Molecular Mimicry In cases asserting molecular mimicry, “there is an important difference between the general theory of molecular mimicry and the more specific theory that the vaccine at issue is capable of triggering an autoimmune response that culminates in the petitioner’s injury.” Duncan v. Sec’y of Health & Hum. Servs., 153 Fed. Cl. 642, 661 (2021) (cleaned up). To establish causation through molecular mimicry, the petitioner must show that “the relevant autoantibodies that are known to drive, or are at least associated with, the resulting [ ] disease are likely produced as a result of the [ ] vaccine” at issue. Morgan v. Sec’y of Health & Hum. Servs., 148 Fed. Cl. 454, 468 (2020). Without empirical evidence that molecular mimicry occurs between a given vaccine and disease, “that general theory could be used to demonstrate an association between virtually any combination of antigens and autoimmune injuries,” in which case “the first prong of Althen would be rendered meaningless.” Caves v. Sec’y of Health & Human Servs., 100 Fed. Cl. 119, 135 (2011), aff’d without opn., 463 F. App’x 932 (Fed. Cir. 2012). The special master explained that theories of molecular mimicry generally require the petitioner to provide “some evidence that persuasively shows that a portion of a vaccine resembles a portion of human tissue,” that it is a homology, “which contributes to causing the disease, and that the immune system will respond to the relevant amino acid sequence.”10 Entitlement Decision, at *20 (citing Tullio v. Sec’y of Health & Hum. Servs., No. 15-51V, 2019 WL 7580149, at *12-14 (Fed. Cl. Spec. Mstr. Dec. 19, 2019), mot. For rev. denied, 149 Fed. Cl. 448 (2020)). The special master also relied on other vaccine cases that he concluded supported this approach. Entitlement Decision, at *21 (citing Morgan, 148 Fed. Cl. at 476-77; Duncan, 153 Fed. Cl. at 661; Caredio v. Sec’y of Health & Hum. Servs., No. 17-79V, 2021 WL 6058835, at *11 (Fed. Cl. Dec. 3, 2021); Yalacki v. Sec’y of Health & Hum. Servs., 146 Fed. Cl. 80, 91-92 (2019)). He also noted the contrary approach of Patton v. Sec’y of Health & Hum. Servs., 157 Fed. Cl. 159, 169 (2021). Entitlement Decision, at *21. Dr. Zizic introduced an article, Kanduc, showing that “viruses and people have extensive homology.” Id. (citing Darja Kanduc, Peptide cross-reactivity: the original sin of vaccines, 10 Homology can also be defined as “the quality of being homologous; the morphologic identity of corresponding parts; structural similarity due to descent from a common form.” Dorland’s 858. 19 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 20 of 25 4 Front. Biosci. 1393 (2012)). The special master noted that Kanduc pointed out that “the commonness of homology undermines the idea that viral infections lead to autoimmune disease. . . . [A]fter ‘three decades of intensive research in the field . . . the molecular mimicry hypothesis has received no validation.’” Id., at *21 (quoting Kanduc, supra, at 1395). On this same point, Dr. Rose asked rhetorically when testifying, “‘if there is no proof, why should we accept [molecular mimicry] as happening in this case?’” Id. (quoting Tr. 463). The special master found that Dr. Zizic “did not effectively answer Dr. Rose’s question.” Id. Dr. Zizic also relied on a 2017 article, Segal, to identify a supposed homology “with parts of the human body involved in SLE.” Id. (citing Yahel Segal et al., HPV and systemic lupus erythematosus: a mosaic of potential crossreactions, 65 Immunol. Res. 564 (2017)). The special master summarized Dr. Zizic’s testimony as explaining that “an antibody’s attack on complement could interfere with the complement system and end up causing lupus.” Id. at *22. Dr. Zizic testified, however, that “‘we can’t prove that. All I’m saying is there’s great biologic plausibility,’” and that “‘it is very conceivable’” that an “antibody against the components of [the] complement” could cause autoimmune disease, including lupus. Id. (quoting Tr. 735-36). Dr. Rose rejected Dr. Zizic’s hypothesis during his testimony based on the lack of evidence of pathogenesis. Dr. Rose also challenged several aspects of Segal on which Dr. Zizic had relied. Id. The special master carefully reviewed the evidence and the testimony regarding molecular mimicry. He explained why he was persuaded by Dr. Rose’s testimony and his critiques of Segal. In summarizing Dr. Rose’s testimony, the special master found that “[a]ny statement that antibodies to specific proteins cause lupus would exaggerate what is known.” Id. That shortcoming is especially true when, as the special master concluded, “[t]he triggers for lupus are not known.” Id. The special master also pointed out that Dr. Zizic had not established that the identified homology was in a position of the cell such that it could generate antibodies. Id. The petitioner objects to the special master’s reliance on Dr. Rose’s rhetorical question, arguing that Dr. Rose’s usage of the word “proof” indicates the special master required scientific certainty rather than preponderant evidence. (ECF 155 at 38-39.) The petitioner further argues that Dr. Zizic’s testimony explained how molecular mimicry would cause the HPV vaccine to induce SLE. (Id. at 39-41.) The petitioner ends by arguing that the special master’s “analysis legally errs by picking apart the Segal article to the point of absurdity” by requiring the petitioner to have proven that “the pentapeptides from Segal must 1) generate antibodies and 2) must be in the correct location within a cell to produce antibodies. If no scientist could prove this, then how can [the petitioner]?” (Id. at 41.) The petitioner does not cite any caselaw to support these points. The fact that a scientist could not yet prove the mechanism does not necessarily mean the special master required a scientific certainty—scientists equally cannot prove things that are untrue. The special master was aware of the appropriate burden of proof. He noted that “[s]tating that the evidence in this case is insufficient to credit molecular mimicry as a theory by which [the] HPV vaccine can cause SLE is not the same as requiring scientific certainty.” 20 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 21 of 25 Entitlement Decision, at *22. Instead, the special master discounted the petitioner’s theory of molecular mimicry because it lacked evidence “that antibodies to specific proteins cause lupus.” Such evidence is essential, he noted, because “[t]he triggers for lupus are not known.” Id. The special master simply applied the test he identified: while “Segal and others have identified homologous sequences of five amino acids there has not been any persuasive showing that an attack on these pentapeptides would cause lupus.” Id. The petitioner did not prove her claim because she failed to provide evidence that connected the antibodies produced from receiving the HPV vaccine to SLE. See Duncan, 153 Fed. Cl. at 661; Morgan, 148 Fed. Cl. at 468. The special master did not require scientific certainty but found the evidence of a key part of the causal chain was missing based on finding Dr. Rose’s testimony more persuasive than Dr. Zizic’s. The petitioner does not challenge the special master’s reading of caselaw concerning proof for molecular mimicry. (ECF 155 at 38-41.) Instead, the petitioner invites a re-weighing of the evidence by providing a different interpretation of Dr. Zizic’s testimony and Segal. (Id.) “Those findings, which are at the core of the special master’s decision in this case, are largely based on his assessments of the credibility of the witnesses and the relative persuasiveness of the competing medical theories of the case. As such, they are virtually unchallengeable on appeal.” Lampe v. Sec’y of Health & Hum. Servs., 219 F.3d 1357, 1362 (Fed. Cir. 2000). The petitioner has not identified any reason why these findings are arbitrary and capricious or legal error, and so her challenge fails. B. The Second Althen Prong The special master recognized that because the petitioner had failed to meet her burden under the first Althen prong, she could not meet the second. He nevertheless addressed the second prong “for [the] sake of completeness.” Entitlement Decision, at *23. Having upheld the special master’s decision on the first Althen prong, there is no need to address the petitioner’s contentions regarding the second Althen prong because it is not logically possible to prevail if a claim is rejected on the first prong. Following the special master, however, for the sake of completeness, the petitioner’s arguments on the second prong will be addressed here. The special master considered the testimony of Dr. Zizic and letters from the petitioner’s treating rheumatologist and primary care physician, Dr. Saba and Dr. Robinson, in evaluating the second Althen prong. He also considered a letter from her treating dermatologist, Dr. Breza, addressing alternative causes for her illness. The special master concluded that Dr. Robinson’s letter might have been sufficient to support entitlement, except for two reasons. First, he reiterated that the petitioner failed to meet her burden under the first Althen prong. Second, the special master found that it was more likely that the petitioner’s acne medication caused the petitioner’s lupus, not the HPV vaccine. In so doing, the special master rejected Dr. Breza’s contention that because the petitioner’s “‘symptoms have not resolved several years after discontinuation of minocycline, I can be certain that minocycline was not the cause of her connective tissue disorder.’” Entitlement Decision, at *26 (quoting Dr. Breza’s letter) (noting that Dr. Breza relied on T. M. Lawson et al., 21 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 22 of 25 Minocycline-induced lupus: clinical features and response to rechallenge, 40 Rheum. (Oxford) 329 (2001)). The petitioner objects to the special master’s rejection of Dr. Zizic’s testimony and Dr. Saba’s letter on causation, as well as his rejection of Dr. Breza’s letter on alternate causes. 1. Evidence from the Petitioner’s Treating Rheumatologist and Expert Rheumatologist on Causation a. Dr. Saba The petitioner’s treating rheumatologist, Dr. Saba, submitted a letter in which she claimed that it was “‘very possible’” that the HPV vaccine caused the petitioner’s connective tissue disease. Id. at *24 (quoting Ex. 22). While acknowledging the probative value of evidence from treating physicians, the special master discounted Dr. Saba’s suggestion, finding that “statements from treaters about possibilities provide little, if any, assistance to petitioners who must establish their cases with preponderate evidence.” Id. (citing Paterek, 527 F. App’x at 883; Austin, 141 Fed. Cl. at 280; Doe, 19 Cl. Ct. at 450). The petitioner objects to the special master discounting Dr. Saba’s opinion. She argues that the cases the special master cited are distinguishable because they involved doctors testifying to mere possibilities without support from other evidence, whereas Dr. Saba had support for her view. (ECF 155 at 19-20.) The petitioner also claims, without support, that “Dr. Saba’s language of ‘very possible’ was intended to meet the preponderance of the evidence standard, as she likely did not intend for her letter to fall short of the required legal standard.” (Id. at 19.) She builds on this argument in her reply brief by relying on a dictionary definition of the word “‘very’” and arguing that it means the phrase “very possible” exceeds the probable standard. (ECF 160 at 8-9.) At its core, the petitioner is arguing the special master misread Dr. Saba’s letter by misunderstanding what Dr. Saba meant by “very possible.” That argument goes directly to the quintessential role of the finder of fact: determining what a piece of evidence means when it has multiple, reasonable interpretations. While Dr. Saba may indeed have meant to write that it is probable that the HPV vaccine caused the petitioner’s condition, she did not do so clearly and unequivocally. Physicians are trained scientists, but medicine is an inexact science. Physicians are often careful to express their views with degrees of confidence or certainty; they know how to be more, or less, definite in writing about medical conclusions. Maybe Dr. Saba intended for “very” to convey her sense that causation was more likely than not. The special master’s contrary interpretation of what Dr. Saba intended to convey, however, is not arbitrary and capricious, especially when viewed in the context of the other evidence the special master considered. The special master’s interpretation also reflects a factual conclusion; it does not elevate the petitioner’s burden of proof. See Paterek, 527 Fed. App’x at 882-83. Likewise, the petitioner has not established that the special master erred by discounting what he viewed to be “indeterminant” evidence. Entitlement Decision, at *7. In Paterek, the Federal Circuit reiterated that “the statutory standard requires more than just proof of a plausible 22 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 23 of 25 or possible causal link between the vaccine and the injury.” 527 Fed. App’x at 883 (cleaned up). To be sure, the Federal Circuit did not say that equivocal testimony supported by other evidence can always be discounted. Id. The Federal Circuit did, however, note that an expert’s testimony “that causation was ‘not impossible’ fails to provide support for causation at all.” Id. Just as the special master in Paterek reasonably found that expert testimony that causation was “not impossible” was insufficient, so too here the special master reasonably found that Dr. Saba’s testimony that a connection was “very possible” did not provide sufficient evidence to show causation. This determination was a reasonable interpretation of the words “very possible,” and is neither arbitrary and capricious nor legal error. b. Dr. Zizic Dr. Zizic testified about the petitioner’s condition. The special master found that, while Dr. Zizic established that the petitioner was more likely to develop an autoimmune disease due to her mother’s MS, he never connected this factor to an increased risk of SLE from the HPV vaccine. While Dr. Zizic testified as to the temporal connection between the HPV vaccine and the petitioner’s illness, the special master concluded that his testimony was not enough to satisfy the second Althen prong. Entitlement Decision, at *24. The petitioner raises two objections to the special master’s treatment of Dr. Zizic’s testimony. First, she argues that the special master raised her burden of proof by improperly requiring her to produce evidence that does not and cannot exist. According to the petitioner, the special master effectively required her to present a study that “would require gathering enough people with 1) a family history of [MS], 2) the receipt of the HPV vaccine and 3) the development of lupus.” (ECF 155 at 21.) Second, she argues she “cannot effectively challenge general and broad statements such as ‘Dr. Zizic does not identify any facts about [the petitioner] that suggests her lupus was due to the vaccine,’” other than pointing generally to Dr. Zizic’s testimony. (Id. at 21-22 (quoting Entitlement Decision, at *24).) The petitioner’s arguments again amount to her objecting that the special master weighed the evidence and was not persuaded by Dr. Zizic’s testimony. Under the second Althen prong, a petitioner must show “a logical sequence of cause and effect showing that the vaccination was the reason for the injury.” Althen, 418 F.3d at 1278. The petitioner has not cited any caselaw that suggests she need not meet this burden when such evidence does not or cannot exist. She put her evidence before the special master; the special master evaluated her evidence and the respondent’s evidence, and based his findings, which he explained, on that evidence. The petitioner has similarly failed to point out an aspect of Dr. Zizic’s testimony that the special master overlooked or “failed to consider genuinely the evidentiary record.” Campbell, 97 Fed. Cl. at 668. The special master fulfilled his role. 2. Dr. Breza and Alternative Causes of the Petitioner’s Condition Dr. Breza, the petitioner’s treating dermatologist, submitted a letter in which he opined that minocycline did not cause the petitioner’s connective-tissue disorder, because her symptoms had not resolved, even several years after she discontinued taking this medication. Entitlement 23 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 24 of 25 Decision at *7, 26 (citing Ex. 24). The special master considered this evidence but ultimately found that it was undermined by El-Hallak, which showed that lupus problems could persist years after a person discontinued taking minocycline. Id. at *26-27 (citing Moussa El-Hallak et al., Chronic minocycline-induced autoimmunity in children, 153 J. Pediatr. 314 (2008)). The special master also relied on the testimony of Dr. Rose, who opined that the petitioner’s series of health problems reminded him of a case of minocycline-induced lupus that he had treated, including “an acute onset of problems, a vasculitic rash, constitutional symptoms, low ANA, robust sed rate, and minor to moderate liver abnormalities.” Id. at *26. Based on Dr. Rose’s testimony, the special master also found that “[a] person with minocycline-induced lupus can develop ‘real’ lupus.” Id. at *27. The special master noted that Dr. Zizic did not rebut this opinion evidence from Dr. Rose, and that it was unclear whether the petitioner was still suffering from lupus symptoms. Id. at *26-27. After noting the evidence in favor of drug-induced lupus, the special master concluded that “the evidence does not preponderate in favor of finding that the HPV vaccination can cause SLE. This disparity means that tetracycline is a more likely explanation even if the likelihood of tetracycline is not more likely than not.” Id. at *27. According to the petitioner, this conclusion was legal error because it minimized the opinion of one of the petitioner’s treating physicians. The petitioner also relies on the special master’s statement that the respondent had not shown that tetracycline was a more-likely-than- not cause of her lupus to imply that the special master committed legal error by not properly applying Althen’s burden-shifting framework. (ECF 155 at 42-43.) The petitioner’s argument again fails. The petitioner ignores the special master’s finding that she failed to provide preponderant evidence that the HPV vaccination can cause SLE. Entitlement Decision, at *23. She also fails to show that the special master’s finding, based on unrebutted evidence, that tetracyclines can cause drug-induced lupus was erroneous. Id. at *25- 26. Instead, she complains that simply because there were a few cases of drug-induced lupus does not mean that the petitioner herself suffered from drug-induced lupus. Id. (citing El-Hallak, supra). The special master did not find, however, that the petitioner is more likely to have suffered from drug-induced lupus; he only found that “[a]mong these two alternatives (HPV vaccine and tetracyclines), tetracycline is a better explanation.” Id. at *27. In fact, the special master went on to note that it is quite possible that the petitioner’s lupus was caused by something else, because “the cause of SLE in the vast majority of cases is unknown.” Id. at *27 n.25. In short, the special master did not find that the petitioner’s acne medication was a more likely cause of the petitioner’s lupus. He instead found that the unrebutted evidence of drug- induced lupus was more persuasive than the rebutted evidence of vaccine-induced lupus as the cause of the petitioner’s illness. Admittedly, this conclusion required him to discount Dr. Breza’s opinion that the petitioner did not suffer from drug-induced lupus. The special master had evidence from a study and Dr. Rose that, contrary to the express basis of Dr. Breza’s opinion, supported his conclusion that a person can suffer from drug-induced lupus even years after discontinuing the drug. The special master weighed the competing evidence and reached a 24 Case 1:18-vv-00056-RAH Document 166 Filed 04/11/24 Page 25 of 25 reasonable conclusion based on the evidence. The petitioner has again failed to point out evidence the special master overlooked or ignored. His decision is entitled to great weight. V. CONCLUSION The special master appropriately evaluated the evidence before him and did not raise the petitioner’s burden of proof; the special master applied the appropriate legal standards. His conclusion that the petitioner did not meet her burden to demonstrate by preponderant evidence that she met the first and second Althen prongs was not arbitrary and capricious. Accordingly, the special master’s decision is sustained. The petitioner’s motion for review (ECF 152) is DENIED. The Clerk is DIRECTED to enter judgment for the respondent. It is so ORDERED. s/ Richard A. Hertling Richard A. Hertling Judge 25
