No correlation between MMR vaccine rates and autism. JAMA. 2001;285(9):1183-118
“Results Essentially no correlation was observed between the secular trend of early childhood MMR immunization rates in California and the secular trend in numbers of children with autism enrolled in California’s regional service center system. For the 1980-1994 birth cohorts, a marked, sustained increase in autism case numbers was noted, from 44 cases per 100 000 live births in the 1980 cohort to 208 cases per 100 000 live births in the 1994 cohort (a 373% relative increase), but changes in early childhood MMR immunization coverage over the same time period were much smaller and of shorter duration. Immunization coverage by the age of 24 months increased from 72% to 82%, a relative increase of only 14%, over the same time period.
Conclusions These data do not suggest an association between MMR immunization among young children and an increase in autism occurrence”

“Conclusions Vaccination with MMR or other MCV, or the timing of vaccination early in life, did not increase the risk for IBD.”

“CONCLUSIONS:
We did not identify any association between MMR vaccination and encephalitis, aseptic meningitis, or autism.”

This study provides strong evidence against the hypothesis that MMR vaccination causes autism.”
