Thimerosal Preservative - Biotech, Pharma and Life Science Channel

19:42 EDT 4th October 2015 | BioPortfolio

Thimerosal is a mercury-based preservative that has been used for decades in the United States in multi-dose vials (vials containing more than one dose) of some vaccines to prevent the growth of germs, bacteria and fungi, that can contaminate them.

What are preservatives and why are they sometimes used in vaccines?

Preservatives have been used in vaccines for more than 70 years and are added to vaccines to prevent the growth of bacteria or fungi that could possibly make the vaccine in multi-dose vials unsafe. This may occur when a syringe needle enters a vial as a vaccine is being prepared for administration. Contamination by germs in a vaccine could cause serious infections.
