Sovanna Sin v. HHS - Tdap, shoulder injury related to vaccine administration (SIRVA) (2025)

Sovanna Sin filed a petition on December 1, 2020, alleging that a Tdap vaccine administered on July 12, 2018, caused a shoulder injury related to vaccine administration. The public stipulation materials do not provide a detailed treatment timeline.

Respondent denied that Ms. Sin sustained a SIRVA Table injury, denied that the Tdap vaccine caused her alleged shoulder injury or any other injury, and denied that her current condition was a vaccine-related sequela.

The parties nevertheless resolved the case by stipulation. Special Master Thomas L.

Gowen adopted the stipulation on June 9, 2025. Ms.

Sin received $48,000.00 in vaccine compensation plus $2,915.91 in additional compensation reflected in the stipulation, for a total injury award of $50,915.91. Later fee decisions concerned attorney fees and costs only.

Ms. Sin was represented by Ronald Craig Homer of Conway Homer, P.C. in Boston, Massachusetts.
