Thimerosal is a preservative that was added to vaccines to prevent microbial contamination. Thimerosal contains approximately 49% ethylmercury. Currently, all routinely recommended licensed pediatric vaccines that are currently being manufactured for the U.S. market contain no thimerosal or only trace amounts.
