Study reveals no connection between MMR vaccine and autism
The 11-year study involved 95,000 children and focused on children who had older siblings diagnosed with autism. The researchers looked for the risk rate of children developing autism after receiving the MMR vaccine in comparison to the risk rate of children developing autism when they had not received the MMR vaccine. The study’s authors discovered no evidence that children with the first one or two doses of the MMR vaccine are at an increased risk of having autism.
"We found that there was no harmful association between the receipt of the MMR vaccine and the development of an autism spectrum disorder," Anjali Jain, a pediatrician at the Virginia health-care consulting firm Lewin Group, said. "Although there is a lot of research suggesting that there is no link between the MMR vaccine and autism spectrum disorder, those beliefs continue to persist. Their vaccination rates were about 10 percent less than for kids with unaffected siblings.”
More details about the study are available in the Journal of the American Medical Association.
