Dooms,
“What exactly does this study prove?”
It appears that Health was referring to this study. JAMA 2275444
“Conclusions and Relevance In this large sample of privately insured children with older siblings, receipt of the MMR vaccine was not associated with increased risk of ASD, regardless of whether older siblings had ASD. These findings indicate no harmful association between MMR vaccine receipt and ASD even among children already at higher risk for ASD.”
Does this answer your question?
