Philip Dahl v. HHS - Influenza, Guillain-Barre syndrome (2025)

On November 1, 2024, Philip Dahl filed a petition alleging that an influenza vaccine administered on October 17, 2022 caused Guillain-Barre syndrome. Respondent conceded entitlement in an August 2025 Rule 4(c) report, agreeing that Mr.

Dahl suffered GBS after a seasonal flu vaccine and met the Vaccine Act requirements for compensation. The public ruling does not describe the first neurologic symptoms, diagnostic testing, hospitalization, immune treatment, rehabilitation, or residual deficits.

Chief Special Master Brian H. Corcoran found Mr.

Dahl entitled to compensation on August 19, 2025. Damages remained to be determined.
