Michael Grigsby v. HHS - Tdap, chronic inflammatory demyelinating polyneuropathy (CIDP) (2025)
Case summary [AI summaries can sometimes make mistakes]
On September 27, 2024, Michael Grigsby filed a petition alleging that a Tdap vaccination administered on January 30, 2023 caused chronic inflammatory demyelinating polyneuropathy. Respondent reviewed the claim and recommended against compensation.
The public fee decision states that respondent's concern centered on the long period between vaccination and the first neurological symptoms, but it also noted that petitioner had supplied sworn testimony and medical records sufficient to support reasonable basis for filing the claim. After respondent's position, Mr.
Grigsby moved to dismiss the petition. Special Master Christian J.
Moran dismissed the case on September 23, 2025. No injury compensation was awarded.
A later attorney-fee decision was limited to fees and costs and did not change the dismissed outcome.
