As the parent of a soon to be 15 year old boy with severe Autistic Disorder I have never attributed his autism disorder to vaccines. I have always accepted the view of public health authorities that there is little or no evidence linking autism to vaccines. With that mindset I never endorsed Jenny McCarthy's views of autism and vaccines although I admired her courage in fighting for her son.
At the other end of the vaccine autism battlefield I support vaccine programs generally as vitally important public health tools but I have become increasingly concerned by the campaign to discredit those who question vaccine safety and the certainty with which Vaccine Generals like Dr. Paul Offit and Dr. David H. Gorski aka Orac have declared that all vaccines and vaccine ingredients can never cause any autism disorder in any child. Given the lack of certainty about what autism is biologically, given the shifting autism definitions used to attack what appears to be an obvious and astounding increase in autism disorders, I don't see how the epidemiological studies can be that definitive. A particular question for me is whether the studies have actually ruled out the possibility that vaccines given to pregnant women might cause or trigger autism in the children they are carrying. Another major question arises from the failure to conduct studies comparing autism rates in existing vaccinated and unvaccinated populations.
It is interesting that a direct comparison of narcolepsy rates was made between those who were vaccinated with the H1N1 vaccine and those who were not. On the autism front former CDC directors Dr. Bernadine Healy and Dr. Julie Gerberding have both been reported in the past as stating that a comparison of autism rates amongst existing vaccinated and unvaccinated populations could and should be done. Their advice has been actively resisted by public health spokespersons. Dr. Offit and Dr. Gorski, each in their own way, will now undoubtedly be called upon to quell any concerns about vaccines and narcolepsy.
Meanwhile the comparative study of autism rates in existing vaccinated and unvaccinated populations will not be done. Unfortunately.
