Study of 1.3 Million Kids Reveals Vaccines Aren't Associated with Autism - io9 A meta-analysis including nearly 1.3 million children posted online last week in the journal Vaccine has demonstrated, once again, that there's no causal link between vaccines and autism. The paper is an online "uncorrected proof." The paper has already been through peer review and has been accepted, but there could still be a few tweaks. Usually, that means fixing typos and such. From the abstract: Findings of this meta-analysis suggest that vaccinations are not associated with the development of autism or autism spectrum disorder. Furthermore, the components of the vaccines (thimerosal or mercury) or multiple vaccines (MMR) are not associated with the development of autism or autism spectrum disorder.
