Donna Martin v. HHS - Influenza, Microscopic Polyangiitis (MPA) (2024)

Donna Martin, a 56-year-old adult, received an influenza vaccine on November 17, 2014. She subsequently developed Microscopic Polyangiitis (MPA), a rare autoimmune disease affecting small blood vessels, which she alleged was caused by the vaccine.

Her symptoms, including fatigue and a neurogenic cough, began approximately two weeks after vaccination, with initial diagnoses including upper respiratory infection and dermatitis. The case proceeded as an off-Table claim, meaning Ms.

Martin had to prove a causal link between the vaccine and her injury. She presented expert testimony from a rheumatologist and an immunologist who argued for a mechanism involving immune system activation and molecular mimicry, suggesting the vaccine triggered her MPA.

Respondent argued that the scientific literature lacked sufficient evidence to link influenza vaccines to vasculitis and proposed alternative causes such as a viral upper respiratory infection or medication side effects. The court reviewed the medical records, expert opinions, and legal precedents, including the Althen test for causation.

Ultimately, the court found that Ms. Martin failed to present preponderant evidence of a legally probable causation theory linking the flu vaccine to MPA.

The court noted that her treaters consistently diagnosed her with a URI, and that isolated case studies, while sometimes used for rare conditions, did not provide sufficient evidence of causation in this instance. Therefore, Ms.

Martin's claim was dismissed.
