Documents both ends of the thimerosal story: the 1999 PHS/AAP/manufacturer removal agreement, and the June 25-26, 2025 ACIP 5-1 vote — adopted by the Secretary on July 22, 2025 — that all influenza vaccines for children 18 and under, pregnant women and adults be thimerosal-free single-dose presentations. Manufacturers confirmed capacity so VFC supply is uninterrupted.
