Wilbert L. Townsend, Sr. v. HHS - Influenza, multiple sclerosis (2023)

Wilbert L. Townsend, Sr., a 57-year-old male, filed a petition alleging that his influenza vaccination on October 4, 2011, caused him to develop multiple sclerosis (MS).

The respondent argued against compensation, stating the case was not appropriate for compensation under the Vaccine Act. The central dispute was whether Petitioner could prove causation under the three Althen prongs.

Petitioner's experts, Dr. Rosenspire and Dr.

Samuels, proposed molecular mimicry and bystander activation as potential mechanisms linking the flu vaccine to MS, citing the rarity of late-onset MS in Petitioner's case. Dr.

West, a treating physician, opined the vaccine led to the onset of MS but did not explain his reasoning. Respondent's experts, Dr.

Tompkins and Dr. Alexander, presented extensive epidemiological data and literature reviews indicating no association between flu vaccination and MS.

They argued that molecular mimicry was unlikely to be the cause and that Petitioner's symptoms were more likely related to a prior upper respiratory infection or other unrelated factors. The Special Master found that Petitioner failed to provide preponderant evidence of a sound and reliable medical theory connecting the flu vaccine to MS (Althen prong one).

The Special Master also concluded that Petitioner failed to demonstrate a logical sequence of cause and effect showing the vaccine caused his MS, even if prong one had been met (Althen prong two). The petition was ultimately dismissed because Petitioner did not meet his burden of proof for causation.

The Court of Federal Claims later reviewed this decision and upheld the Special Master's findings, denying Petitioner's motion for review.
