Acta microbiologica et immunologica Hungarica, 52(1), 95-103 (2005-06-17)
The common preservative thimerosal is one of the most important organic mercury compounds human populations are exposed to. It has toxic effect on several cell lines, and it also induces programmed cell death in in vitro experiments. Association is suggested

There is a need to interpret neurotoxic studies to help deal with uncertainties surrounding pregnant mothers, newborns and young children who must receive repeated doses of Thimerosal-containing vaccines (TCVs). This review integrates information derived from emerging experimental studies (in vitro

To compare epidemiological studies dealing with neurological issues (compatible with Hg toxicity) linked to exposing newborns and infants to intramuscular doses of preservative-Hg resulting from vaccination with thimerosal-containing vaccines (TCV). Major databases were searched for studies that addressed neurodevelopment outcomes

On July 7, 1999, the American Academy of Pediatrics and the US Public Health Service issued a joint statement calling for removal of thimerosal, a mercury-containing preservative, from vaccines. This action was prompted in part by a risk assessment from

The decomposition rate of organomercurials and the potency of the blood-brain barrier increase with the size of the organic radical. Thus methylmercury damages the brain more than thimerosal does, and when intake limits set for methylmercury are applied to thimerosal
