Mariann Mattia v. HHS - Influenza, shoulder injury related to vaccine administration (SIRVA) (2025)

On October 11, 2022, Mariann Mattia filed a petition alleging that an influenza vaccination administered on September 10, 2020 caused a Table shoulder injury related to vaccine administration. She alleged residual effects lasting more than six months.

Respondent denied that Ms. Mattia sustained a Table SIRVA and denied vaccine causation.

The public stipulation does not describe onset, medical visits, imaging, injections, physical therapy, or expert opinions. The parties resolved liability and damages through a joint stipulation filed March 27, 2025.

On April 15, 2025, Chief Special Master Corcoran adopted the stipulation and awarded $47,500.00 as a lump sum through counsel for all damages available under the Vaccine Act. A later fee decision was separate from the injury award.
