Autism rates in vaccinated and unvaccinated children

"You would need a group of children not vaccinated from birth, and compare them with children vaccinated with and without Thimerosal from birth."

These sorts of studies have been done.

For instance, there was a scare involving the MMR vaccine and supposed links to autism. It turns out that unvaccinated kids get autism at the same rate as vaccinated ones.

"Perhaps the best study was that performed by Madsen and colleagues in Denmark between 1991 and 1998 and reported in the New England Journal of Medicine. The study included 537,303 children representing 2,129,864 person-years of study. Approximately 82 percent of children had received the MMR vaccine. The group of children was selected from the Danish Civil Registration System, vaccination status was obtained from the Danish National Board of Health, and children with autism were identified from the Danish Central Register. The risk of autism in the group of vaccinated children was the same as that in unvaccinated children. Furthermore, there was no association between the age at the time of vaccination, the time since vaccination, or the date of vaccination and the development of autism."

It was also reported by antivax advocates that unvaccinated Amish children don't get autism. This is false.

"To conclude that vaccines cannot be the cause of Autism because they removed one possibly toxic ingredient and replaced it with something else, possibly toxic, is flat out idiocy."

"Idiocy" is one word to describe persistent antivax hysteria over this issue, in the face of overwhelming evidence that vaccination does _not_ cause autism. it can be hard to give up these foolish prejudices, but antivaxers need to reexamine their dogged fanaticism against life-saving vaccines.
