(Reuters Health) - The measles, mumps and rubella (MMR) vaccine is not linked to development of autism spectrum disorders, even among children considered to be at risk, a large new study finds.

Among nearly 100,000 children, receipt of the MMR vaccine did not increase the risk for autism spectrum disorder (ASD), regardless of whether kids were at higher risk because an older sibling already had the condition, researchers write in JAMA.

"Even for children who are high-risk, the vaccine does not play a role," said lead author Dr. Anjali Jain of healthcare consulting firm The Lewin Group in Falls Church, Virginia. "We don't know what does unfortunately, but it's not the MMR vaccine."

The results should be reassuring, she said.


Autism spectrum disorder is a range of symptoms that often includes difficulties with communication and social interaction, according to the U.S. National Institute of Mental Health. It's may also include restricted and repetitive behaviors.


The 1998 study that claimed to find a connection between the MMR vaccine and ASD was later debunked. The Lancet, the medical journal that originally published it, withdrew it. Studies continue to vouch for the safety of the vaccine.


Still, some people continue to believe that the vaccine is connected to ASD.


Parents of children with ASD may also believe there is a genetic component, and so they decline to vaccinate their other children, Jain and colleagues noted in their report in the Journal of the American Medical Association.


For the new study, the researchers used insurance claims data on 95,727 children followed from birth to at least age five between 2001 and 2012. They also had data on the children's older siblings.


Overall, about 2 percent of the children had an older sibling with ASD. Those children were more likely to go on to develop ASD themselves whether they were vaccinated or not, according to the report.


The vaccine didn't increase their risk, the researchers say.

For example, among high-risk five year olds, ASD developed in 23 of 269 who weren't vaccinated (8.6 percent), compared to 30 of 796 (3.8 percent) who received two doses of the MMR vaccine.

Among kids not at high risk of ASD, 7,735 were unvaccinated at age five and 56 (0.7 percent) were diagnosed with the condition. That compared to 244 of 45,568 children (0.5 percent) who received two MMR doses.


Furthermore, children with an older sibling with ASD were significantly less likely to have received the MMR vaccine in the first place.


By age five, about 92 percent of the children without ASD in the family had received at least one MMR dose. By comparison, only 86 percent of children with an older sibling with ASD had been vaccinated by that age.


"I think it's important to show that the degree of undervaccination in the families with children with autism spectrum disorder was significant," Jain told Reuters Health.

Alongside the lack of association between the vaccine and ASD, the undervaccination rate deserves attention, she said.


Roughly a dozen studies have shown that age of ASD onset and its severity do not differ between vaccinated and unvaccinated children, wrote Dr. Bryan King, program director of the Autism Center at Seattle Children's Hospital, in an editorial accompanying the new study.


The new study, King added, now shows that "the risk of ASD recurrence in families does not differ between vaccinated and unvaccinated children."

But what about that temporal association between vaccinations and profound mental disorders that Dr. Rand Paul formerly known as Sen. Rand Paul spoke of?

Obviously the syndrome at play was a temporal lobe disassociation on the part of Dr. Paul

I find it ridiculous that immigrants are supposed to be vaccinated but people born in the US have a choice. It shouldn't be a choice, not if you wish to remain in the US.

What do you propose to do with the USC morons who won't vaccinate, and the USC people who can't get vaccinated due to medical issues? Should we banish them to Plum Island?

Plum Island. Sounds like a plan. Let's go with that.

Educated people are saying that the vaccine is safe, do you believe them?

They should be barred from enrolling their children in public schools to curtail the potential spread of a disease. So yes, I think they should be banished to their own little vaccine free paradise where they can deal with the outcomes of their foolishness away from society at large. I'm being sarcastic of course...

I think most of this "anti-vaccine" madness would go away if they offered an "organic" version of each vaccine for two or three times the normal price.

That, sad is it may be, is a brilliant solution. .. I may borrow that

Too funny. I went to Maui about 2 weeks ago and had an organic smoothie called a Maui girl. Cost 8$. I have to say, it was the best smoothie I've ever had. Now I'm trying organic food...
