Thomas Dido, Sr. v. HHS - Tdap, chronic inflammatory demyelinating polyneuropathy (CIDP), myasthenia gravis, and/or myopathy (2026)

Thomas Dido, Sr. filed his petition on January 18, 2024, alleging that vaccines administered on January 6, 2023 caused chronic inflammatory demyelinating polyneuropathy, myasthenia gravis, and/or myopathy. The covered vaccines identified in the decision were influenza, tetanus-diphtheria-acellular pertussis (Tdap), and pneumococcal conjugate (PCV20) vaccines.

The decision also notes that he received a non-covered zoster vaccine the same day. Respondent denied that the flu, Tdap, and/or PCV20 vaccines caused Mr.

Dido's alleged injuries and denied that the vaccines caused any other injury or current disability. The public stipulation does not describe his first neurologic symptom, weakness pattern, eye or bulbar symptoms, diagnostic testing, EMG or nerve conduction findings, antibody testing, imaging, hospitalization, IVIG or steroid treatment, or long-term functional limitations.

The available public story is therefore a settlement record rather than a medical narrative: Mr. Dido attributed a serious neuromuscular illness to three covered vaccines administered on January 6, 2023; respondent denied causation; and the parties resolved the disputed claim by stipulation.

Special Master Nora Beth Dorsey found the stipulation reasonable and adopted it on January 5, 2026. He received $120,000.00 as a lump sum through counsel's IOLTA account.
