Joey Nilson v. HHS - MMR, encephalopathy following cardiorespiratory arrest (2006)

Joey Nilson, a five-year-old boy, received DTaP, MMR, and Polio vaccines on October 11, 1996. The day after vaccination, on October 12, 1996, he collapsed and experienced cardiorespiratory arrest, leading to encephalopathy and his death on October 19, 1996.

His father filed a claim under the National Childhood Vaccine Injury Act of 1986, arguing that his son's medical problems constituted a Table injury or that the vaccines were the cause-in-fact of Joey's death. The Special Master denied the claim on both counts.

The Special Master found that while Joey suffered an encephalopathy within the Table's timeframe, the government successfully rebutted the presumption of causation by showing that factors unrelated to the vaccines caused the injury. Respondent's expert, Dr.

Max Wiznitzer, a board-certified neurologist, pediatrician, and psychiatrist specializing in child neurology, testified that Joey's encephalopathy was caused by a metabolic disturbance, likely stemming from an asthma attack leading to cardiac arrest, which was unrelated to the vaccines. Dr.

Wiznitzer opined that Joey's pre-existing conditions, such as reactive airway disease or a potential heart rhythm disturbance, caused the cardiac arrest. The Special Master found Dr.

Wiznitzer's testimony more persuasive than that of the petitioner's expert, Dr. Stephanie Cave, a family physician, who argued the vaccines were toxic.

The Special Master noted that Dr. Cave's testimony lacked appropriate validation and relied on speculation, citing weaknesses in VAERS data and theories not applicable to Joey's condition.

The court affirmed the Special Master's decision, agreeing that the government met its burden to show factors unrelated to the vaccine caused the injury. The petitioner's claim was denied.

The court noted that the petitioner had abandoned his causation-in-fact claim during briefing. The Special Master's decision was affirmed because it rested upon a rational basis supported by the record and the testimony of the medical experts.
