James McMahon v. HHS - Influenza, left shoulder injury related to vaccine administration (SIRVA) (2025)

On July 31, 2024, James McMahon filed a petition seeking compensation under the National Vaccine Injury Compensation Program. He alleged that an influenza vaccination administered on November 6, 2023 caused a left shoulder injury related to vaccine administration, a Table SIRVA, and that the residual effects lasted for more than six months.

Respondent conceded entitlement in a Rule 4(c) report filed February 3, 2025, stating that Mr. McMahon's injury was consistent with the Vaccine Injury Table's SIRVA definition and that the legal prerequisites for compensation were met.

Chief Special Master Brian H. Corcoran granted entitlement on February 4, 2025.

The public entitlement and damages documents do not describe Mr. McMahon's first symptom, medical visits, imaging, injections, therapy, work limitations, or later clinical course.

The damages record instead proceeded by proffer. Respondent noted that additional records filed after the Rule 4(c) report included left-shoulder medical records and then proffered $100,100.00.

On May 8, 2025, the Chief Special Master awarded that amount as a lump sum through counsel, consisting of $100,000.00 for actual and projected pain and suffering, reduced to net present value where required, and $100.00 for past unreimbursed expenses. Later attorney-fee proceedings were separate from the injury award.
