Dr. Singh's testing showed positive autoantibodies to myelin basic protein and elevated MMR antibodies, which he attributed to an atypical measles infection from the MMR vaccination. The government's expert, Dr. Shafrir, countered that Noah's condition was more consistent with regressive autism, citing family history and the absence of evidence for an MMR-induced encephalopathy or autistic enterocolitis. The Special Master denied the claim, finding insufficient evidence of encephalopathy, imprecise parental recollections of symptom onset, and that Noah's symptoms aligned with the typical age of autism onset.

The petition, filed on May 27, 2004, alleged that Noah suffered an encephalopathy caused by the Measles-Mumps-Rubella (MMR) vaccine administered on May 14, 1999, which manifested as autistic-like symptoms and developmental delays. The respondent was the Secretary of Health and Human Services.\n\nNoah Dixon received several vaccinations in infancy without documented adverse reactions. His development was noted as normal through 13 months of age, with records indicating he could roll, sit, vocalize, walk, play pat-a-cake, and wave bye-bye. He experienced a bronchospasm/asthma exacerbation at 8 months and reactive airway disease at 13 months.\n\nOn May 14, 1999, at approximately 16 months old, Noah received the MMR, Hib, and Varicella vaccines. According to his mother, on the following day, May 15, 1999, Noah exhibited severe projectile vomiting and diarrhea for ten days. His medical records are sparse for the five months following this vaccination. His grandmother observed him about a month later, on June 17, 1999, describing him as fussy, feverish, and vomiting, and stating he was \"not himself.\" During a visit in August 1999, she noted he did not talk, screamed in frustration, threw himself on the floor, ate paper and wood, and required constant supervision.\n\nBy October 27, 1999, Noah's pediatric clinic noted \"disturbing signs\" including excessive drooling, repetitive noise-making, grunting, and reaching for objects, with diagnoses of possible URI, viral conjunctivitis, probable language delay, and suspected developmental delay. A subsequent well-baby exam on November 3, 1999, documented significant regression: Noah could no longer walk or talk, exhibited pica (eating wood and paper), ran stiffly, could not walk up stairs or sit normally, and could not speak two-word sentences. His pediatrician noted his older sibling had Asperger's syndrome and his father had ADHD, diagnosing pica and possible ADHD or autism spectrum disorder. Neurodevelopmental team evaluations in early 2000 confirmed diagnoses of autism with moderate developmental delay and pica.\n\nThe petitioners' experts included Dr. F. Edward Yazbak (pediatrician, autism researcher), Dr. Thomas A. Schweller (pediatric neurologist), Dr. Mark Geier (geneticist, vaccine epidemiology), and Dr. Vijendra K. Singh (who found positive autoantibodies to myelin basic protein and elevated MMR antibodies). They opined that the MMR vaccine caused an encephalopathy. The government's expert, Dr. Yuvak Shafrir (child neurologist), concluded Noah's condition was more indicative of regressive autism, citing the family history and absence of documented neurological reaction or autistic enterocolitis. Dr. Lawrence Moulton, a biostatistician, challenged Dr. Geier's statistical methods.\n\nThe Special Master denied the claim, finding that the petitioners failed to prove an encephalopathy, noting that none of the developmental specialists' evaluations supported such a notion. The Special Master also found the parents' recollections of timing to be imprecise and vague, and that Noah's symptoms appeared around the age when autism evidence typically emerges. The Special Master found Dr. Shafrir's evaluation persuasive, particularly the lack of documented neurological reaction or autistic enterocolitis, and the absence of a clear temporal relationship between the vaccination and symptom onset.\n\nThe Court of Federal Claims affirmed the Special Master's decision. The court reviewed the Special Master's factual findings under the arbitrary and capricious standard and legal conclusions under the not-in-accordance-with-law standard. The court found the Special Master's reliance on Dr. Shafrir was not arbitrary or capricious, and that proximate temporal association alone, without more, does not establish causation-in-fact under the Vaccine Act. The court concluded that the petitioners did not meet their burden of proving by a preponderance of the evidence that the vaccine was the cause of Noah's condition, and dismissed the petition with prejudice. The court acknowledged the family's tragedy and the challenges in understanding regressive autism but found the Special Master's decision was supported by the record.","is_minor_inferred":1,"is_pediatric_broad":1,"special_master":null,"petitioner_identifier_original":null,"caption_petitioner_name":null,"petitioner_attorney_name":null,"petitioner_attorney_firm":null,"petitioner_attorney_location":null,"adjudicator_name":null,"caption_people_backfilled_at":null,"attorney_canonical_keys":null,"firm_canonical_key":null,"package_title":"Dixon v.
