AI-assisted case summary:
On January 8, 2021, Lucio Villanueva filed a petition alleging that an influenza vaccination on September 24, 2020 caused a right shoulder SIRVA. He was 83 years old at vaccination. After his unrelated death on November 5, 2022, his daughter and personal representative, Susan V. Mendoza, was substituted as petitioner.

The case turned on which arm received the flu vaccine. The vaccination record placed the flu shot in Mr. Villanueva's left deltoid, but Mr. Villanueva later asserted that he had been injected twice and that the flu vaccine had actually been placed in his right arm. The medical record complicated that story. In 2018 he had been treated for right shoulder pain, osteoarthritis of the acromioclavicular joint, and calcific tendinitis. Two days after the 2020 vaccination, he presented with right shoulder swelling, and later imaging showed a subacromial spur and partial tears. During early physical therapy and orthopedic care, he and his daughter attributed his symptoms to an older fall, and an orthopedist later recorded that the pain had been present for a long time.

The first clear medical-record connection to the flu shot appeared in December 2020, when a neurologist noted dementia and a family history that Mr. Villanueva had been mistakenly injected twice. Days later, an orthopedist aspirated cloudy joint fluid, and an infectious-disease specialist diagnosed Methicillin-susceptible Staphylococcus aureus septic arthritis. Ms. Mendoza later produced a more complete urgent-care record saying the pain followed a flu shot two days earlier, but Chief Special Master Brian H. Corcoran found its probative value limited by the unclear change history and by the fact that the history still came from Mr. Villanueva.

On September 29, 2025, Chief Special Master Corcoran dismissed the case for insufficient evidence. He found that the preponderant evidence showed the influenza vaccine was given only in the left arm, not the right shoulder alleged as injured, and that other record problems would likely have been fatal as well. No compensation was awarded. Mr. Villanueva was represented by Leah VaSahnja Durant, and respondent by Alec Saxe.

Theory of causation field:
Influenza vaccine, September 24, 2020, age 83, alleged right SIRVA/Table injury or caused-in-fact/significant aggravation. DISMISSED. Theory depended on proving that the flu vaccine was mistakenly administered in the right arm despite the vaccine record showing the left deltoid. Respondent argued situs failure and pre-existing right shoulder disease. Key evidence: 2018 right shoulder osteoarthritis/calcific tendinitis, September 26, 2020 right shoulder swelling, MRI partial tears/spur, October PT history attributing symptoms to an old fall, November orthopedist noting long-standing pain, December MSSA septic arthritis, dementia affecting memory, and a later urgent-care record with uncertain change history. Mr. Villanueva died November 5, 2022 from unrelated causes and Susan V. Mendoza was substituted. Chief Special Master Corcoran September 29, 2025. No award. Attorney Leah Durant; respondent Alec Saxe.

DECISION DISMISSING CASE1
On January 8, 2021, Lucio Villanueva filed a petition for compensation under the
National Vaccine Injury Compensation Program, 42 U.S.C. §300aa-10, et seq.2 (the
“Vaccine Act”). Mr. Villanueva alleged that he suffered a right shoulder injury related to
vaccine administration (“SIRVA”), a defined Table Injury, or in the alternative a caused-
in-fact or significant aggravation injury, after receiving an influenza (“flu”) vaccine on
September 24, 2020. Amended Petition, filed Sept. 28, 2022, at 1, ¶¶ 1, 8, ECF No. 24.
Following Mr. Villanueva’s death from unrelated causes on November 5, 2022, Susan V.

Mendoza (his daughter and personal representative of his estate) was substituted as
Petitioner. ECF Nos. 28-32.
I hereby DENY entitlement in this case, because Petitioner cannot preponderantly
establish that Mr. Villanueva received the flu vaccine in his right deltoid as alleged.
Additionally, there are significant other deficiencies which further undercut Petitioner’s
claim. Thus, entitlement cannot be substantiated – even pursuant to a causation-in-fact
or significant aggravation claim – and dismissal of the matter is appropriate.
I. Relevant Procedural History
Due most likely to the then-potential removal of SIRVA from the Vaccine Program’s
injury table,3 and the concomitant need to act quickly, Mr. Villanueva filed a cursory
petition without accompanying medical records or appropriate citations to those records.
Petition, filed Jan. 8, 2021, ECF No. 1. Fifteen months later, he filed the declaration4 and
medical records required by the Vaccine Act. Exs. 1-10, filed Apr. 7, 2022, ECF No. 17;
see Section 11(c). On June 16, 2022, the case was activated and assigned to the “Special
Processing Unit” (OSM’s adjudicatory system for resolution of cases deemed likely to
settle). ECF No. 20.
On September 28, 2022, Mr. Villanueva filed an amended petition with additional
detail and medical records citations. ECF No. 24. Approximately nine months thereafter,
following the death of her father, Ms. Mendoza was substituted as Petitioner. ECF No.
32.
On August 25, 2023, Respondent filed his Rule 4(c) Report opposing
compensation. ECF No. 34. He argued therein that Mr. Villanueva received the flu vaccine
in his left deltoid as the vaccine record states, rather than the right deltoid as alleged. Id.
at 11-18. Thus, he insisted that Petitioner could not prove any vaccine-related injury,
given the situs of that injury. Id. at 18-20.
3 On July 20, 2020, the Secretary of Health and Human Services proposed the removal of SIRVA from the
Vaccine Injury Table. National Vaccine Injury Compensation Program: Revisions to the Vaccine Injury
Table, Proposed Rule, 85 Fed. Reg. 43794 (July 20, 2020). The proposed rule was finalized six months
later. National Vaccine Injury Compensation Program: Revisions to the Vaccine Injury Table, Final Rule,
86 Fed. Reg. 6249 (Jan. 21, 2021). Approximately one month later, the effective date for the final rule was
delayed. National Vaccine Injury Compensation Program: Revisions to the Vaccine Injury Table, Delay of
Effective Date, 86 Fed. Reg. 10835 (Feb. 23, 2021) (delaying the effective date of the final rule until April
23, 2021). On April 22, 2021, the final rule removing SIRVA from the Vaccine Table was rescinded. National
Vaccine Injury Compensation Program: Revisions to the Vaccine Injury Table, Withdrawal of Final Rule, 86
Fed. Reg. 21209 (Apr. 22, 2021).
4 This declaration was signed under penalty of perjury as required by 28 U.S.C.A. § 1746. Ex. 10.

Case 1:21-vv-00358-UNJ Document 40 Filed 10/30/25 Page 3 of 8
On October 21, 2024, I ordered Petitioner to show cause why her claim should not
be dismissed for insufficient evidence, given Respondent’s situs argument. In response,
Petitioner filed certified medical records from Mr. Villaneuva’s urgent care treatment in
September 2020; a copy of the subpoena authorized and served upon her primary care
provider (“PCP”) in November 2021; a status report expressing Petitioner’s belief that
there are PCP medical records supportive of her claim which had not yet been provided,
and a response addressing the issues raised in my order. Exs. 15-16, filed Nov. 15, 2024,
ECF No. 36; Status Report, filed Nov. 15, 2024, ECF No. 37; Petitioner’s Response to
Order to Show Cause (“Show Cause Response”), filed Dec. 8, 2024, ECF No. 38. In her
response, Petitioner again insists there is a September 24, 2020 treatment record which
Mr. Villanueva’s PCP refuses to provide, even in response to a subpoena served on
November 9, 2021, which is supportive of her claim. Show Cause Response at 2-4.
II. Analysis Related to Situs
A. Mr. Villanueva’s Assertions
The vaccine record in this case states that Mr. Villaneuva received the flu vaccine
on September 24, 2020, in his left, rather than right, deltoid (and thus is contrary to
Petitioner’s allegations). Ex. 1. Even though this record is the type of documentation that
was likely created in a computer with a dropdown menu, it still warrants some evidentiary
weight.
In the initial petition, Mr. Villanueva stated simply that he “was vaccinated in the
right deltoid on or about September 24, 2020” (Petition at ¶ 1) and “experienced pain in
his vaccinated shoulder” within 48 hours (id. at ¶ 2). In his sworn declaration, executed
and filed approximately fifteen months later, on April 7, 2022, he provided further detail.
Ex. 10. Mr. Villanueva stated that he received the flu vaccine when at his PCP’s clinic for
a physical examination, accompanied by his wife (who was also receiving a physical) and
his daughter. Id. at ¶ 1. He explained that, while his wife and daughter were in the
bathroom, the PCP’s assistant
collected my urine and drew blood on my right arm and gave me an injection
on my right upper arm. Then after that, [the PCP] came in to give me the flu
shot on my left upper arm. During that time, I was the only one in the room
as my daughter had to accompany my wife to the restroom to get [a] urine
sample. When my wife and daughter came back, [the PCP] gave my wife
the flu shot.
3

Case 1:21-vv-00358-UNJ Document 40 Filed 10/30/25 Page 4 of 8
Id. at ¶ 2 (emphasis added).5
Mr. Villanueva maintained that he related these events to his wife and daughter
the next day after experiencing fever and pain and swelling in his right upper arm, adding
that his daughter informed the PCP of the mistake. Ex. 10 at ¶ 2. He also recounted a trip
to the PCP’s clinic on October 1, 2020, the purpose of which was to discover what exactly
had occurred on September 24, 2020, including the identity of the assistant who drew his
blood and administered the right arm flu shot. Id. at ¶¶ 5-6. Mr. Villanueva insisted that
his failure to recognize the assistant in question was because she was wearing a mask
and gown when she drew his blood and administered the flu vaccine. Id. at ¶ 6. Although
he did not provide affidavits or sworn declarations from his wife, daughter, or
granddaughter, attesting to these events, he did seek subpoena authority in November
2021, which revealed no additional medical records from his PCP.
In an amended petition filed on September 28, 2022, Mr. Villanueva again alleged
that he received the flu vaccine in his right deltoid, even though the vaccine record reflects
a left arm injection site. Amended Petition at ¶¶ 1, 1 n.1. Insisting the vaccine record is
incorrect, Mr. Villanueva asserted that “[a]ll medical records in this case reflect an injury
and treatment that were administered to [his] right arm.” Id. at ¶ 1 n.1.
Information in the Contemporaneously Created Medical Records
Evidence contained in the contemporaneously created medical records do not
corroborate the witness statement contentions on situs. They instead portray Mr.
Villanueva as possessing prior and current conditions which could easily account for his
right shoulder pain. And both Mr. Villanueva and his daughter attributed his symptoms to
his prior condition during initial PT and orthopedic appointments in October and
November 2020. Furthermore, the contemporaneously-created medical records show Mr.
Villanueva was previously diagnosed with dementia. Thus, his memory was unfortunately
less reliable during this time, and his recollections are otherwise not adequately supported
by additional evidence.
In August and September 2018 (approximately two years prior to vaccination), Mr.
Villanueva (83 years old at the time) was treated for right shoulder pain as well as neck
and back pain, and tingling in both hands. Ex. 5 at 11, 116-37. X-rays of his right shoulder
taken on August 7, 2018, revealed “[o]steoarthritis of the acromioclavicular joint [and]
5 Although Petitioner alleges that he received a flu vaccine in his left arm on September 24, 2020, in his
initial and amended petitions, Mr. Villanueva’s sworn declaration states only that he received an “injection”
after having his blood drawn from his right arm. Ex. 10 at ¶ 2. The omission of the specific type of injection
Mr. Villanueva believes he received may be due to simple oversight, but it also may be an indication that
he did not feel comfortable definitively stating that the injection was likely the flu vaccine.

[c]alcific tendinitis.” Id. at 123. The physician ordered pain medication, joint cream, a right
shoulder MRI, an EMG, and physical therapy (“PT”). Id. at 114-22. The EMG revealed
“decreased nerve conduction” of the right and left ulnar sensory nerves, but it does not
appear that Mr. Villanueva attended PT or underwent the prescribed MRI. Id. at 132.
Additionally, Mr. Villanueva’s right shoulder pain diagnosis was included in a list of
diagnoses discussed during a February 12, 2019 appointment with his PCP when treated
for dizziness and knee pain. Ex. 2 at 20.
On September 26, 2020 (two days post-vaccination), Mr. Villanueva visited an
urgent care facility complaining of right shoulder swelling. Ex. 8. The earlier provided
medical record6 from this visit notes that he was accompanied by his daughter, an LPN.7
Ex. 8. Observing swelling and painful range of motion (“ROM”), but no fracture on x-rays
taken,8 the urgent care physician prescribed cephalexin9 and provided a referral for an
MRI. Id. That MRI (performed on September 27, 2020) revealed multiple findings,
including a “[l]ateral subacromion spur indenting the supraspinatus tendon and partial
tears of the supraspinatus tendon and deltoid, biceps, and triceps muscles. Ex. 4 at 32.
On October 15, 2020, Mr. Villanueva began PT based on his PCP’s referral. Ex. 3
at 4; see Ex. 2 at 42 (PT referral). At the initial evaluation, it was noted that both Mr.
Villanueva and his daughter (who accompanied him) attributed his right shoulder
symptoms to a fall at least four years prior. Ex. 3 at 4. Mr. Villanueva reported that the fall
had occurred ten years ago, while his daughter placed its occurrence “4-5 years ago.” Id.
Mr. Villanueva continued to attend PT throughout October to early December 2020. See
Ex. 3.
On November 4, 2020, Mr. Villanueva sought treatment for his right shoulder pain
from an orthopedist. Ex. 6 at 16. At this visit, he reported that his pain had been present
“for a long time,” but was recently increasing. Id. The orthopedist instructed Mr. Villanueva
to use Tylenol and Voltaren gel to control his pain and to continue his PT as tolerated. Id.
On December 3, 2020, Mr. Villanueva (accompanied by his granddaughter) was
seen by a neurologist for dementia, “characterized by short term memory loss, intact long

term memory, asking the same questions over and over, and increased irritability and
agitation, especially towards his wife.” Ex. 4 at 13. Previously diagnosed by another
physician, Mr. Villanueva had declined the recommended medication. At this visit, his
granddaughter reported that Mr. Villanueva suffered from right shoulder pain since
mistakenly being injected twice when receiving the flu vaccine in September 2020. Id.
This entry is the first mention of the flu vaccine as a potential cause of Mr. Villanueva’s
right shoulder symptoms.
When Mr. Villanueva was next seen by his orthopedist two days later, he elected
to receive a steroid injection to help combat his right shoulder pain. Ex. 6 at 12. Before
administering the injection, the orthopedist performed an arthrocentesis of the joint which
revealed cloudy fluid. Id. at 12-13. This sample was sent for testing. Id. at 13.
When seen by an infectious disease specialist three days later, Mr. Villanueva was
diagnosed with Methicillin-susceptible Staphylococcus aureus (“MSSA”), consistent with
MSSA septic arthritis. Ex. 7 at 10. Accompanied by his granddaughter, who reported that
Mr. Villanueva’s daughter was a nurse who could assist with any at home infusion, Mr.
Villanueva was prescribed an extended course of IV cefazolin.10 Id. At this visit, it was
noted that Mr. Villanueva “initially attributed [his right shoulder pain] to the influenza
vaccine which he received in the same arm.” Id. at 9.
In January 2021, Mr. Villanueva transitioned to oral antibiotics. Ex. 7 at 5. He
continued to attend PT through July 2021. E.g., Ex. 9 at 60-65 (PT discharge summary).
B. Evidence Offered Ater Ms. Mendoza’s Substitution as
Petitioner
After her substitution as Petitioner in this case, Respondent’s objection to
compensation, and my discussion of the noted deficiencies, Ms. Mendoza expressed a
desire to continue to this vaccine claim. To that end, she provided a more complete
medical record from the urgent care appointment Mr. Villaneuva attended two days post-
vaccination on September 26, 2020, a copy of the subpoena served on Mr. Villanueva’s
PCP, and argument emphasizing her belief that Mr. Villanueva’s PCP possess medical
records related to vaccination that he has not provided which would be supportive of
Petitioner’s claim.
The medical record from Mr. Villanueva’s September 26, 2020 visit to urgent care
that Petitioner provided in November 2024, shows it was obtained in April 2024. Ex. 15
at 1 (certification executed on March 5, 2024). And it contains a history which includes a

Case 1:21-vv-00358-UNJ Document 40 Filed 10/30/25 Page 7 of 8
sudden onset from a flu shot administered two days earlier. Id. at 4. However, there is an
unexplained asterisk beside the mention of a flu shot as follows:
(id. at 4). In addition, multiple notations of “Change History” can be found in the different
sections of the record (id. at 4-7). Although these notations may be innocuous, their
meaning cannot be ascertain given the dearth of information related to the process by
which this record was procured. Petitioner has failed to describe how this later version of
the record was obtained, or attest to whether any information was added to the record on
a post hoc basis, in an attempt to supplement or clarify the record.
Although this later-provided urgent care record provides some addition support - if
determined to be an accurate, contemporaneously created recitation - of the information
Petitioner provided in 2020, its probative value is still undercut by the fact that it is based
upon information originating only from Mr. Villanueva. And the uncertainty created by Mr.
Villanueva’s failure in October and November 2020 to mention the flu shot, instead
suggesting his symptoms were due to a prior condition, still remains.
Petitioner insists that Mr. Villanueva’s PCP possesses additional documentation
supportive of her claim, but the record does not support this assertion. According to even
Mr. Villanueva’s account of the events in question, his PCP disputed his claim of the
administration of two flu vaccines at the relevant time. Mt. Villanueva was asked to identify
the assistant he believed had administered an earlier flu shot in his right arm and was
unable to do so. The PCP has provided a vaccine record showing administration in
Petitioner’s left arm and resisted attempts to alter or supplement that record.
Had Petitioner provided more readily-available evidence to substantiate Mr.
Villanueva’s account of the events that occurred in late 2020 and as described in this
Decision, I would be more likely to see the wisdom of further efforts to obtain additional
information from Mr. Villanueva’s PCP. But given the overall record in this case (which
includes other deficiencies related to prior and current conditions more likely to have
caused Mr. Villanueva’s symptoms), it is unlikely that Petitioner will prevail either on the
situs issue or remaining requirements for entitlement. Thus, I find such further efforts are
not warranted.
I have no doubt that Mr. Villanueva truly believed that he received some type of
injection (thought to be a flu vaccine) in his right deltoid after a blood draw by his PCP’s
assistant, followed by a flu vaccine administered as stated in the vaccine record by his
PCP. But considering the record as a whole, to include Mr. Villanueva’s diagnosed
dementia, and the likelihood that he experienced only a blood draw or different injection,
7

Case 1:21-vv-00358-UNJ Document 40 Filed 10/30/25 Page 8 of 8
Petitioner has failed to provide the preponderant evidence needed to support his
recollection of these events. Even if Mr. Villanueva suffered some immediate right
reaction aggravating his right shoulder condition, Petitioner has failed to preponderantly
show this was due to a flu vaccine, mistakenly administered in his right arm, in addition
to the one noted in his vaccine record that was administered in his left arm.
Conclusion
The Vaccine Act prohibits me from finding a petitioner entitled to compensation
based upon the petitioner’s claims alone. Section 13(a). To date, and despite ample
opportunity, Petitioner has failed to provide the evidence needed to establish that Mr.
Villaneuva likely received a flu vaccine on September 24, 2020, in his right deltoid as
alleged. Instead, the preponderant evidence supports a flu vaccine given only in his left
deltoid. In addition, there appear to be other deficiencies likely fatal to this claim, and no
other version of the claim would likely be tenable.
Petitioner was informed that failure to provide preponderant evidence to overcome
the situs defect would be treated as either a failure to prosecute this claim or as an inability
to provide supporting documentation for this claim. Accordingly, this case is DISMISSED
for insufficient evidence. The Clerk of Court shall enter judgment accordingly.11
IT IS SO ORDERED.
