Mercury preservative in vaccines can cause autism, because they do not have the time to build up in the body of the child. American scientists have found that the half-life thimerosal is much shorter than previously thought, according to the journal Pediatrics. Researchers from the University of Rochester (New York) observed 216 children in the Argentine Gutierrez Children's Hospital (Buenos Aires). According to the immunization schedule for children administered vaccine that was in the preservative thimerosal, which contains ethyl mercury. In newborns, and two and six months old - before and after shots - ethyl mercury content was determined in the blood. It was found that in all age groups, the half-life (the time during which the concentration of a substance in the body is reduced by 50%) is less than four days of ethyl. For comparison, the half-life of other mercury-containing substances - methyl mercury that occurs in marine fish, about ten times longer and is 44 days, the researchers reported. "Until recently it was believed that both types of mercury have a large half-life Now it is obvious that the short half-life of ethyl mercury prevents the accumulation of toxins, too, he was quickly withdrawn..", - Said the head of research Michael Pichichero ( Michael Pichichero). The scientist said that the blood of children aged six months mercury concentration before the next vaccination (in the course of their lives was the largest number of ethylmercury has introduced) about the same as that of the two-month child was. Speculation about a possible link between certain vaccines and autism was published in the late 90s. According to the "vaccination" hypothesis, the growth in autism in the Western countries as side effects of vaccines are mercury-containing preservative thimerosal. Despite the fact that this theory by most scientists on the basis of large epidemiological studies has been rejected, many parents and pediatricians continue to adhere to it.
