In a win for the Make America Healthy Again (MAHA) movement, the Advisory Committee on Immunization Practices (ACIP) voted 5-1 to limit flu vaccines to only those free of thimerosal. The mercury-containing preservative, largely phased out of childhood vaccines by 2001, still lingers in some multi-dose flu shots. But with 96% of U.S. flu vaccines for the 2024-2025 season already thimerosal-free, single-dose options are not hard to come by.
The committee, freshly revamped by Health and Human Services (HHS) Secretary Robert F. Kennedy Jr., also voted 5-1 to mandate thimerosal-free flu vaccines for children 18 and under and pregnant women.
The effort to remove thimerosal began in the late 1990s, sparked by growing public and scientific scrutiny of mercury exposure. In 1997, the FDA Modernization Act prompted a review of mercury in medical products, including thimerosal, a mercury-based preservative used since the 1930s to prevent microbial contamination in multi-dose vaccine vials.
