As the father of a child with mild ASD, I take more than a passing interest in the topic. There were some recent Congressional hearings on autism in which the absolute nutters got yet another chance to air their nutty conspiracy theories about vaccines causing autism. These people are the biggest threat to advancing our understanding of autism, research on autism and the future care of those with autism. There is no controversy about this. The evidence is absolutely 100% clear that autism is not caused by vaccines. What these people are doing by manufacturing a controversy is diverting money, resources and energy away from the things that can make a difference in the lives of those with autism. Please get over it.
