HHS Finalizes Removal of Thimerosal from All U.S. Influenza Vaccines
SHERIDAN, WYOMING – July 25, 2025 – In a significant move reshaping national vaccine policy, the U.S. Department of Health and Human Services (HHS) has announced it will eliminate thimerosal from all influenza vaccines distributed in the United States. The decision follows a unanimous vote by the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices (ACIP) on June 26, 2025, and marks the end of an era for a preservative that has been both a practical necessity and a source of public debate for over two decades.
