Karyn Mason-Chavez v. HHS - Tdap, shoulder injury related to vaccine administration (SIRVA) (2023)

Karyn Mason-Chavez filed a petition for compensation under the National Vaccine Injury Compensation Program on October 8, 2021, alleging she suffered a Shoulder Injury Related to Vaccine Administration (SIRVA) after receiving a Tdap vaccine in her left arm on September 30, 2020. She stated the vaccine was administered in the United States, the residual effects lasted over six months, and she had no prior history of shoulder issues.

The respondent conceded entitlement, agreeing that her pain occurred within 48 hours post-vaccination, was limited to the injection site, and no other condition explained the pain. A ruling on entitlement was issued on June 20, 2023.

Subsequently, on October 17, 2023, the respondent proffered an award of $72,000.00 for pain and suffering, which the petitioner accepted. The Chief Special Master issued a decision awarding this lump sum payment on November 20, 2023.
