Denise Rojas Hernandez v. HHS - Tdap, mass, cyst, or other neoplasm on the left shoulder (2026)

On October 20, 2022, Denise Rojas Hernandez filed a petition alleging that a Tdap vaccination administered on October 23, 2019 caused a reaction diagnosed as a mass, cyst, or other neoplasm on her left shoulder. She alleged residual effects lasting more than six months, administration in the United States, and no prior civil recovery.

Respondent denied that the alleged mass, cyst, or neoplasm or its residual effects were caused in fact by the Tdap vaccine, and denied that the Tdap vaccine caused any other injury or current condition. The case resolved by stipulation, and the public decision does not provide a fuller medical timeline.

On March 17, 2026, Chief Special Master Brian H. Corcoran found the stipulation reasonable and awarded $750.00 as a lump sum payable through counsel's IOLTA account for prompt disbursement to Ms.

Hernandez.
