Karen Kun v. HHS - Influenza, Guillain-Barre syndrome (GBS) (2025)

On October 22, 2024, Karen Kun filed a petition alleging that an influenza vaccine administered on October 21, 2021 caused Guillain-Barre syndrome. Respondent conceded entitlement, agreeing that Ms.

Kun satisfied the Table criteria for GBS after influenza vaccination, that the claim was timely, that the vaccine was administered in the United States, and that residual effects lasted more than six months. The public ruling does not describe the first neurologic symptoms, diagnostic testing, hospitalization, immune treatment, rehabilitation, or residual deficits.

Special Master Christian J. Moran found Ms.

Kun entitled to compensation on August 8, 2025. Damages remained to be determined.
