Nadya Lazarev v. HHS - Influenza, shoulder injury related to vaccine administration (SIRVA) (2026)

On May 19, 2025, Nadya Lazarev filed a petition alleging that an influenza vaccination administered on October 13, 2023 caused a shoulder injury related to vaccine administration. She alleged residual effects lasting more than six months and no prior civil award or settlement for the injury.

Respondent conceded entitlement in a Rule 4(c) report filed March 23, 2026. The concession stated that Ms.

Lazarev had no history of pain, inflammation, or dysfunction in her left shoulder before vaccination; that shoulder pain occurred within forty-eight hours after the intramuscular flu vaccination; that pain and reduced range of motion were limited to the vaccinated shoulder; and that no other condition or abnormality explained the shoulder pain. Chief Special Master Brian H.

Corcoran found Ms. Lazarev entitled to compensation on March 25, 2026.

The available public record resolves entitlement only and does not include a damages award or a fuller treatment chronology.
