A new study indicates that postnatal exposure to thimerosal, a mercury preservative commonly used in a number of childhood vaccines, can lead to the development of autism-like damage in autoimmune disease susceptible mice. This animal model, the first to show that the administration of low-dose ethylmercury can lead to behavioral and neurological changes in the developing brain, reinforces previous studies showing that a genetic predisposition affects risk in combination with certain environmental triggers. The study was conducted by researchers at the Jerome L. and Dawn Greene Infectious Disease Laboratory at the Mailman School of Public Health, Columbia University.
