 Many studies have failed to conclude that there is a causal link between autism spectrum disorders and vaccines, and the current scientific consensus is that routine childhood vaccines are not linked to the development of autism.Several claimants have attempted to bypass the VICP process with claims that thimerosal in vaccines had caused autism, but these were ultimately not successful.They have demanded medical monitoring for vaccinated children who do not show signs of autism and have filed class-action suits on behalf of parents.
