Though I agree that vaccinations should be given/gotten, when they say there is NO CORRELATION between MMR and Autism or anything else for that matter, it simply means there is not a "statistical relevance". Yet, I know 2 families personally that have had a perfectly healthy child's life destroyed and their family's life as well immediately following MMR. In one case, the child developed an extremely rare form of autoimmune condition of the central nervous system. It is hopeful that he can lead a reasonably normal life but periodically has to go have a rare form of low dose chemotherapy which has associated risks up to and including death. The other family, the child developed an extremely high fever, went into seizure, and has permanent [non autism] brain damage. This child will never have any semblance of normalcy and neither will his family. BOTH infants were developing completely normally prior to MMR.
Though I openly acknowledge that I am not a doctor, did not stay at Holiday Inn Express last night, and I am probably an outlier that I know [2] families, I do have several friends/acquaintances that each know of [1] each, plus I am 60 so I acknowledge I have been around a while but these things DO happen. They are simply not statistically relevant given the millions of vaccinations given. When it happens to you though, relevance takes on a whole new meaning. Just food for thought. Could they break up MMR into 3 vaccinations to reduce risks? Could studies be funded on a statistically relevant sample of normal developing infants that had sudden autism or otherwise onset post MMR to see if there is some genetic predisposition that could be tested for? I am certain there are other arguments one way or the other.
