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

Maryann Nadeau filed a petition alleging she suffered a shoulder injury related to vaccine administration (SIRVA) after receiving an influenza vaccine on November 9, 2021. She stated the vaccine was administered in the United States, she experienced residual effects for more than six months, and no related lawsuits had been filed.

The respondent, the Secretary of Health and Human Services, filed a Rule 4(c) report conceding that Ms. Nadeau is entitled to compensation.

The respondent agreed that her injury was consistent with SIRVA as defined by the Vaccine Injury Table, noting she had no prior shoulder issues, the pain occurred within 48 hours of vaccination, and the pain and reduced range of motion were limited to the injection site. The respondent also agreed that Ms.

Nadeau satisfied the legal prerequisites for compensation, including suffering residual effects for more than six months. Based on the respondent's concession and the evidence, the Chief Special Master found Ms.

Nadeau entitled to compensation. The case will proceed to determine the award amount.
