A Vaccine Act plaintiff failed to show by a preponderance of the evidence that a flu vaccination caused damage to her autonomic nerves, the Federal Circuit has ruled in affirming a special master’s determination that she was not entitled to compensation.
The plaintiff, a 41-year-old woman, got a flu shot in November 2003 and a week later felt tired, achy and nauseated. She later developed dizziness and weakness that continued for months. A neurologist she saw concluded that it was “certainly possible” she had developed dysautonomic neuropathy from the flu vaccination.
After a series of tests on the plaintiff’s autonomic nervous system – which keeps the body’s internal systems in balance – a specialist found the “it was unclear” whether autonomic dysfunction contributed to her symptoms. Another neurologist found that her symptoms were “suggestive” of autonomic neuropathy.
The plaintiff filed a claim under the Vaccine Act under the theory that the flu vaccine caused an autoimmune reaction that damaged her autonomic neuropathy.
A special master held a two-day hearing and concluded that the preponderance of the evidence showed that the plaintiff did not have autonomic neuropathy. The Court of Federal Claims agreed, and the Federal Circuit affirmed.
“[The plaintiff’s] theory of causation is that the vaccine provoked her immune system to attack her autonomic nerves, causing damage to those nerves that manifested as dysautonomia. … “Therefore, even assuming the medical plausibility of [her] theory of causation – that the vaccine triggered an immune response that damaged her autonomic nerves – her failure to show that she had autonomic neuropathy [is] fatal to her case,” the court said.
A dissenting judge complained that the majority opinion was not using the correct burden-shifting framework.
