[2011 Sept] The Vaccine Establishment’s SAFETY Debate: Use of Thimerosal in vaccines Versus the admittedly dangerous use of methylmercury these studies, as brought to light by Dr. King, establish that ethylmercury (Thimerosal), a “supposedly harmless” compound of mercury according to the vaccine establishment, is converted in the rat [1] and apparently in the human infant [2] into “methylmercury” which, the establishment admits is a harmful form of mercury.
Several pages of the paper examine the toxicity of methylmercury and its past use as a fungicide. We are led to believe that this form of mercury is much different than ethylmercury, the type found in vaccines. This is in spite of the fact that ethylmercury was used for the same purpose. In fact, Ethylmercurric Chloride, the material used as a fungicide (which was banned long ago) is what is used to make thimerosal. This can be easily confirmed by looking in a Merck Index. We now know that this type of mercury deposits twice as much inorganic mercury in the brains of primates as compared to equal doses of methylmercury (4). Inorganic mercury, following the de-methylation of organic mercury, has been identified as the primary neurotoxic agent in primate studies (5).
The author mentions the book, "Evidence of Harm: Mercury in Vaccines and the Autism Epidemic" by David Kirby. It contains 436 scientific references. The author did not disclose if he read the book. This may have helped his argument since this book was read by many parents of autistic children. (4) Burbacher T, Shen D, Liberato N, Grant K, Cernichiari E, Clarkson T. 2005.

LES INCOMPETANTS: OPEN LETTER TO THE AAP By K. Paul Stoller, M.D.
Health officials often claim that ethylmercury—the type of mercury found in vaccines containing thimerosal—should not be compared to methylmercury, a well-established neurotoxin. However, a Russian study found that adults exposed to much lower concentrations of ethylmercury than those given to American children still suffered brain damage years later. In 1985, the Archives of Toxicology published a comparative study that administered similar doses of ethylmercury and methylmercury to rats. The ethylmercury-treated rats had higher amounts of inorganic mercury in their kidneys and brains.91 In August 2005, a study funded by the National Institutes of Health also found that ethylmercury is more toxic to the brain than methylmercury. It crosses the blood-brain barrier quicker and converts to inorganic mercury—which is more difficult to excrete and stays in the brain longer—at much higher levels.

[EOHarm] Ethyl vs. Methyl

…A second study, which was not discussed this morning, is that adult male and female rats were administered five daily doses of equimolar concentrations of ethyl or methylmercury by gavage and tissue distribution, neurotoxicity, and nephrotoxicity assessed. This was a Magos study in 1985 in the Archives of Toxicology. And the key points of that paper were:
neurotoxicity of methyl and ethylmercury were similar, although higher levels of inorganic mercury were seen in the brains of ethylmercury-treated rats consistent with what we'd said about metabolism; and likewise, because of that, the renal damage was greater in the ethylmercury treated rats.
…I think it is important to note from the Magos study, in which he directly compared ethyl and methylmercury, that he found essentially the same results in both studies, with the exception that the renal toxicity was greater with ethyl, and I think that was because of the demethylation as a way of concentrating the mercuric chloride or inorganic mercury in the kidney.
