Shawn Geiger v. HHS - Tdap, transverse myelitis (2025)

On February 2, 2022, Shawn Geiger filed a petition alleging that a Tdap vaccination administered on April 16, 2019 caused transverse myelitis. The public decision is a joint stipulation rather than a litigated causation ruling, so it does not describe the onset, diagnostic testing, treatment course, or expert opinions.

Respondent denied that the Tdap vaccine caused transverse myelitis or any current condition. The parties nevertheless agreed to resolve the case.

On July 31, 2025, Chief Special Master Brian H. Corcoran adopted the stipulation and awarded Mr.

Geiger $75,000 for all damages available under Section 15(a), payable through counsel's IOLTA account. Mr.

Geiger was represented by Nathaniel Enos of Conway Homer, P.C.
