Thimerosal contains very tiny amounts of ethylmercury, which is safe and quickly leaves the body. It’s different from harmful methylmercury found in some fish. Thimerosal has been used safely in vaccines, drugs, and contact solutions since the 1930s. Decades of studies across the globe have shown that thimerosal is safe in the amounts used in vaccines.
