The Committee on Oversight and Government Reform recently held a hearing on the possible causes of autism and what the Center for Disease Control is doing about it. Vaccines were mentioned. Specifically, how politicians on both sides of the isle suspect the mercury in vaccinations accumulates in the brain to cause autism.
Extensive studies have gone into what causes autism. Vaccines have been ruled out, repeatedly, but that hasn't stopped committee members from suggesting that vaccines cause autism.
Two CDC scientists, Colleen Boyle and Alan Guttmacher, testified before the committee. Rep. Bill Posey (R-FL) asked Boyle if the CDC had conducted a study comparing vaccinated children to unvaccinated children, among many other questions. Boyle replied that they hadn't.
But the reason such a study doesn't exist, Steven Salberg writes for Forbes, is because vaccines would have to be withheld from children. Doing so would be too risky. So why all the concern over the sudden increase in autism? As Salberg explains, it's thanks to a broadening of autism's definition, its awareness, and an increasing number of diagnoses.
