Flu Vaccines

Thimerosal in Flu Vaccines: Most single-dose flu vaccine vials and pre-filled syringes are thimerosal-free. Multi-dose vials may contain trace amounts (typically 25 micrograms per dose) as a preservative, but thimerosal-free flu vaccines are widely offered, especially for children and pregnant women.

•  Checking for Mercury-Free Vaccines:

If you or someone else is receiving a vaccine and you want to ensure it’s thimerosal-free, you can:

•  Request a single-dose vial or pre-filled syringe, which are typically thimerosal-free.

•  Ask your healthcare provider or pharmacist to confirm the vaccine’s composition.

•  Check the vaccine’s package insert or consult resources like the CDC or FDA websites for specific formulations.
