Vaccine Cleared Again as Autism Culprit

One example of epigenetics that I think is very well represented in popular media is the vaccines and autism debate.  Many parents, supported by the pseudoscientific study done by Wakefield (described in this article), believe that the MMR vaccine caused autism in their children.  While most reputable science seems to point to the idea that the two are unlinked, the idea of this correlation lives on in the minds of many parents and continues to persist.  Basically the theory is that the vaccine epigenetically changes the expression of genes in the brain.
