is a pharmaceutical preservative with trace mercury that prevents microbes from growing in a medication bottle.
Preliminary results also suggest the possibility of a synergism between thimerosal
exposure and MMR timing leading to a greater risk of autism.
Previously, the CroFab involved the use of thimerosal
, an ethyl mercury-containing compound, to no more than 0.6 mg of mercury per dose (based on the maximum dose of 18 vials used in clinical studies of CroFab).
He lists glyphosate (an herbicide) and thimerosal
(an ingredient in vaccines) in a section about drugs he's consumed.
One meta-analysis in particular analyzed several cohort studies, which included over a million children, and reported there is no connection between autism and the MMR vaccine, thimerosal
, or mercury.
Another scapegoat for a cause of autism has been thimerosal
, a preservative agent that had been used in some vaccines, but never in MMR vaccines.
We further showed that metal ions ([Cu.sup.+], [Pb.sup.2+], [Al.sup.3+], and [Hg.sup.2+]) and the ethylmercury derivative thimerosal
potently blocked IGF-1 stimulation of MS and reduced basal activity to very low or undetectable levels.
Parents can benefit from understanding the difference between methylmercury--which naturally occurs in the environment and is neurotoxic at high levels of exposure--and ethylmercury, which is formed when the body breaks down the thimerosal
that is found in small amounts in some vaccines, Dr.
A concern about mercury emissions from industrial plants led to a concern about mercury in thimerosal
, a vaccine preservative.
These concerns are primarily due to the expansion of the infant immunization schedule and exposure to thimerosal
, once used as a preservative in some vaccines.
One vaccine ingredient that has been studied specifically is thimerosal
, a mercury-based preservative used to prevent contamination of multidose vials of vaccines.
