Study Finds No Link Between MMR Vaccine and Autism

(CNN) — 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.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.”

The work was funded by the National Institute of Mental Health, National Institutes of Health, and the U.S. Department of Health and Human Services.

‘Beliefs continue to persist’

As dozens of measles cases began popping up in the United States in recent months, unfounded fears about a link between vaccines and autism resurfaced.

“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,” said Jain.

The study found that children who had an older sibling with autism were less likely to be vaccinated.

“Their vaccination rates were about 10% less than for kids with unaffected siblings,” Jain said.

The recurrent myth about a link between vaccines and autism, propagated by a small but vocal group of anti-vaccine activists, grew out of a now discredited study from 1998 that was published in a British medical journal by a doctor who was later stripped of his license.

“We’re not sure as a scientific community what causes autism, but vaccines do not,” CNN’s Dr. Sanjay Gupta said last month.

    There is no link, until your perfectly healthy, developmentally normal child receives the vaccines and develops a high fever, constant screaming, brain inflammation, and autism. Good luck to you! May the odds be ever in your favor.

    Check out They have a different opinion on vaccines, and I would believe them before I’d believe ANYTHING on CNN. The news media reports what they’re told to report by big corporations.

      Really? Newworldordernews? That is literally the single most conspiracy theorist thing I’ve ever seen in my life

      Yeah, great, let’s all check out a conspiracy theory website run by undefined sources as a primary source of news. The truth is that the entire anti-vaccine movement has been led by one doctor in England, Andrew Wakefield, who’s license to practice medicine in the UK has now been revoked, and who’s research is almost universally recognized as fraudulent by the scientific community, and one blithering mouthpiece, Jenny McCarthy. It’s sad that so many children are now unprotected from protectible diseases because a couple of idiots.

      Thank god you’re here to tell us all about the plan the Rothschild family is enacting to give infants autism through vaccines so that they grow up to be manchurian candidates who work on the HAARP weather weapon array to do the will of the alien greys by blasting a hole in the hallow Earth so the reptilians can come out and have a family reunion with their long lost relatives, the Bush’s.

      You figured it all out man. -golf clap-
