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

Cynthia Backer filed a petition for compensation under the National Vaccine Injury Compensation Program, alleging she suffered a shoulder injury related to vaccine administration (SIRVA) as a result of an influenza vaccine administered on October 8, 2023. She also alleged, in the alternative, that she developed Parsonage Turner Syndrome caused by the vaccine.

The petition stated that the vaccine was administered in the United States, that she suffered residual effects for more than six months, and that she had not received any settlements or awards for her injury. Respondent filed a Rule 4(c) report conceding that Petitioner is entitled to compensation.

Respondent concluded that Petitioner's injury is consistent with SIRVA as defined by the Vaccine Injury Table and that she satisfied all legal prerequisites for compensation. Based on Respondent's concession and the evidence, the Chief Special Master found Petitioner entitled to compensation.
