(NaturalNews) The toxic effects of the mercury, also known in vaccines as Thimerosal, have once again been confirmed, this time by researchers from the University of Brazil. Marking the sixth major study in recent months to condemn the use of mercury in medicine, the new study reveals that mercury causes serious brain damage, and is linked to autism and other developmental diseases in children and Alzheimer's disease in adults.Dr. Jose Dorea and his colleagues conducted an extensive, peer-reviewed analysis of various studies and available information in major databases that address the effects of low-dose Thimerosal, or ethylmercury, on neural tissue and behavior. They found conclusively that Thimerosal accumulates in brain tissue, negatively affects brain development, and harms brain cells."Mercury is known to cause serious harm, especially to fetuses and children because of their smaller size," said Lisa Sykes, president of the Coalition for Mercury-free Drugs (CoMeD), a non-profit group dedicated to removing mercury from medicine. "Why remove Thimerosal from pediatric vaccines only to inject it into pregnant women and children with recommended flu shots? They removed Thimerosal from other vaccines, so it should also be removed from flu shots."Several other recent studies confirm the numerous dangers posed by mercury, including one recently published in thethat links the toxin directly to autism ( https://www.naturalnews.com/031678_mercury_au... ). Mercury is also known to disrupt proper immune function, damage DNA, inhibit healthy embryonic development, and cause cancer.The vast majority of the flu shots administered in the US still contain Thimerosal, as they come from multi-dose vials that require a preservative in order to prevent contamination. However, CoMeD says there is no reason to continue using Thimerosal since safer alternative preservatives already exist and are currently in use in many pediatric vaccines that used to contain Thimerosal.
