1 Thimerosal contains ethyl mercury. 2  This is a different chemical compound than mercury found in the environment (methylmercury). 3  Thimerosal has been used as a preservative since the 1930s to prevent bacterial growth in vials containing multiple doses of vaccine and other medical products.he majority of influenza vaccines distributed in the United States contain thimerosal as a preservative. However, an increasing amount is thimerosal-free. While the multiple dose vials still have thimerosal to prevent bacterial growth, the single-dose preparations do not.
The single-dose units are made without thimerosal as a preservative because they are intended to be opened and used only once. Additionally, the live-attenuated version of the vaccine (the nasal spray vaccine), is produced in single-dose units and does not contain thimerosal.he most recent and rigorous scientific research does not support the argument that thimerosal-containing vaccines are harmful. CDC and FDA continually evaluate new scientific information about the safety of vaccines.
