Matthew Valentine v. HHS - Influenza, acute transverse myelitis and acute disseminated encephalomyelitis (2025)

On August 18, 2022, Matthew Valentine filed a petition alleging that an influenza vaccination administered on September 11, 2019 caused acute transverse myelitis and acute disseminated encephalomyelitis. He was 37 years old at vaccination.

Respondent denied that Mr. Valentine's alleged TM, ADEM, or residual effects were vaccine-caused.

The public stipulation does not describe onset, diagnostic testing, hospitalization, treatment, expert opinions, or the biological mechanism alleged. On November 20, 2025, Chief Special Master Corcoran adopted the parties' stipulation and awarded $150,000.00 as a lump sum through counsel for all damages available under the Vaccine Act.
