Ashley Koon v. HHS - Tdap, shoulder injury related to vaccine administration (SIRVA) (2025)
Case summary [AI summaries can sometimes make mistakes]
On December 21, 2020, Ashley Koon filed a Vaccine Act petition and later amended it to allege a shoulder injury related to vaccine administration after receiving a Tdap vaccine on July 30, 2020. The case was assigned to the Special Processing Unit.
Respondent conceded entitlement in a Rule 4(c) report filed June 22, 2023. The concession stated that Ms.
Koon's left shoulder injury was consistent with SIRVA as defined by the Vaccine Injury Table and that she had satisfied the legal prerequisites for compensation. Chief Special Master Brian H.
Corcoran entered an entitlement ruling the same day. The parties could not resolve damages on their own.
After briefing, Chief Special Master Corcoran awarded $137,066.59 on August 25, 2025, consisting of $134,000.00 for actual pain and suffering and $3,066.59 for unreimbursed expenses. A later February 5, 2026 attorney-fee decision did not alter the injury award.
