Katherine Patterson v. HHS - Pneumococcal, shoulder injury related to vaccine administration (SIRVA) (2026)

Katherine Patterson filed a petition for compensation under the National Vaccine Injury Compensation Program on March 2, 2026. She alleged that she suffered a shoulder injury related to vaccine administration (SIRVA) as a result of a pneumococcal conjugate vaccination received on September 29, 2022.

Petitioner further alleged that she suffered the residual effects of her injury for more than six months. Respondent filed a Rule 4(c) report conceding that Petitioner is entitled to compensation.

Respondent stated that Petitioner's alleged injury is consistent with SIRVA as defined by the Vaccine Injury Table, noting no prior history of shoulder pain, pain occurring within 48 hours of vaccination, pain limited to the vaccination site, and no other condition explaining the pain. Respondent also confirmed that Petitioner suffered residual effects for more than six months.

Based on Respondent's position and the evidence, the Chief Special Master found Petitioner entitled to compensation, with damages to be determined.
