(Thermerisol)
Thimerosal is a form of ethylmercury, is harmless to humans, and isn't present in most vaccines since 2001. There is no link between Thimerosal and harm from vaccines.
Methylmercury is the type of mercury found in certain kinds of fish. At high exposure levels methylmercury can be toxic to people. In the United States, federal guidelines keep as much methylmercury as possible out of the environment and food, but over a lifetime, everyone is exposed to some methylmercury.
