"...in 2004 the Institute of Medicine panel said evidence against a link is so strong that health authorities, 'whether in the United States or other countries, should not include autism as a potential risk' when formulating immunization policies.
But where is the simple, straightforward study of autism in never-vaccinated U.S. children? Based on our admittedly anecdotal and limited reporting among the Amish, the home-schooled and now Chicago's Homefirst, that may prove to be a significant omission."
I've not read enough to have an intelligent, informed opinion on this controversial matter. On the other hand, I do not have blind faith in the medical community. Being the parent of a child with significant special needs, I've come to the conclusion that much of medicine is a "best guess" effort. I say this not to denigrate medical professionals. We have met many caring doctors in our pursuit of the best medical care for our daughter.
The article (linked in the quote above) was quite interesting.
