If you know none of the details of the antivaccination lunacy, then your education should start with the perpetrator of one of the greatest scientific frauds, Mr. Andy Wakefield. Mr. Wakefield published a paper, subsequently withdrawn by the highly respected medical journal, Lancet, that blamed the MMR vaccine (vaccination for measles, mumps and rubella) for causing autism spectrum disorder (ASD).
From that one fraudulent article, some of the most dangerous outbreaks of vaccine preventable diseases can be laid at the feet of Wakefield, as parents started to refuse to vaccinate their children against these diseases. And of course, billions of dollars, money that could have been spent on actually treating and assisting children with ASD, was spent to investigate this claim, with over 100 peer-reviewed papers completely dismissing and debunking any link between any vaccine and any type of autism. Let me make this absolutely clear–vaccines do not cause autism even when we looked hard for a link.
But one more article, one more peer-reviewed paper has just been published that should slam the door shut on the vaccine-autism myth. But I am not naïve, I know that the antivaccination cultists will invent some logical fallacy to continue to lie about the tie between vaccines and autism. The research, published in the journal Vaccine, is a meta-analysis of five cohort studies involving 1,256,407 children, and five case-control studies involving 9920 children. As I've written before, meta-analyses form the basis, the deep foundation, of the scientific consensus, and they are the highest quality scientific evidence available. This study is like a gigantic clinical trial because it rolls up the highest quality data from those millions of subjects to develop solid conclusions.
