Gary Kastler v. HHS - Influenza, Guillain-Barre syndrome (GBS) (2025)

On September 1, 2023, Gary Kastler filed a petition alleging that an influenza vaccination administered on October 1, 2020 caused Guillain-Barre syndrome. He alleged that the residual effects lasted for more than six months.

Respondent conceded entitlement in a Rule 4(c) report filed April 29, 2025, agreeing that Mr. Kastler satisfied the Vaccine Injury Table and the Qualifications and Aids to Interpretation for a flu-GBS claim.

Chief Special Master Corcoran granted entitlement on May 2, 2025. The public ruling is limited.

It does not describe Mr. Kastler's first neurologic symptom, onset interval beyond the Table framework, emergency care, hospitalization, diagnostic testing, treatment, rehabilitation, or expert opinions.

No damages decision or vaccine-injury compensation award was present in the public text reviewed for this update, so the case remains at entitlement granted with damages pending.
