Three hypotheses have been proposed to support this: the measles-mumps-rubella (MMR) vaccine causes autism by damaging the intestinal lining, allowing the entrance of encephalopathic proteins; thimerosal, an ethylmercury-containing preservative, is toxic to the central nervous system; and the administration of multiple vaccines overwhelms and weakens the immune system. Many researchers along with multiple epidemiological studies have been documented to ensure the safety of vaccinations for parents who will harbor concern for their …show more content…
The notion that children are receiving multiple immunizations and it is leading to autism is flawed in multiple ways. The infant immune system is immediately capable of generating protective responses; vaccinations do not overwhelm the immune system. Vaccinations, although they contain a strain of the disease which aid in the generation of antibodies, do not overpower the immune system. The speculation that an exaggerated or inappropriate immune response to vaccinations precipitates autism is at discrepancy with current scientific data that addresses the pathogenesis of
