Ban aluminum in vaccines

SB 475, introduced in Montana, proposes to ban vaccines containing aluminum as an ingredient for use or administration within the state. It requires vaccine manufacturers and distributors to submit implementation plans within one year, including timelines for removing aluminum-containing vaccines and distributing aluminum-free alternatives. The ban would take effect only after the health department certifies aluminum-free vaccines are available. The bill died in committee in May 2025 and was never enacted into law. It directly affects vaccine providers, manufacturers, and distributors operating in Montana.
