The vaccine for measles, mumps and rubella doesn't bring an increased risk of autism, according to a new study of more than 95,000 children. The study, published Tuesday in the Journal of the American Medical Association, is the latest piece of research to debunk the myth associating the MMR vaccine with autism. Vaccine-autism connection debunked again Using a claims database from a large commercial health plan, the researchers paid particular attention to children who had older siblings with autism, or ASD, which puts them at a higher genetic risk of developing autism. "We found that there was no harmful association between the receipt of the MMR vaccine and the development of an autism spectrum disorder," said Anjali Jain, a pediatrician at the Lewin Group, a health care consulting firm in Virginia, who worked on the study. 'No evidence' of link The team of researchers examined the records of 95,727 children in an 11-year window. They studied the risk of developing autism in children who received the MMR vaccine compared with those who didn't. For children with older siblings diagnosed with autism, the study's authors said they "found no evidence that receipt of either 1 or 2 doses of MMR vaccination was associated with an increased risk of ASD."
