A new study once again proves: No, vaccines do not cause autism

One teen who defied his anti-vax parents to get inoculated became a folk hero of sorts last week.

It concluded that the study "strongly supports that MMR vaccination does not increase the risk for autism, does not trigger autism in susceptible children, and is not associated with clustering of autism cases after vaccination". Will a new study from Denmark - one involving hundreds of thousands of subjects - finally convince the skeptics and activists?

The Centers for Disease Control and many others have long noted there's no proven link between vaccines and autism, and now the agency has yet another study to back those claims. There was no significant increase in rates of autism between children who received the MMR vaccine and those who did not, a major blow to the anti-vaxxer argument, given the significant size of the sample. "Even in the face of substantial and increasing evidence against an MMR-autism association, the discussion around the potential link has contributed to vaccine hesitancy".

Gary Freed, professor of health management and policy at the University of MI, expressed similar thoughts.

With measles outbreaks reported in several states, researchers hope a new study can further reassure parents that vaccines are safe and the MMR vaccine for measles, mumps and rubella does not increase the risk of autism.

The news about the London patient also encourages Paula Cannon at the University of Southern California in Los Angeles. Scientists are looking at finding a way to inject a patient with modified immune cells that can resist the HIV virus.

Researchers followed more than 657,000 children born from 1999 to December 2010.

Boys were four times more likely to be diagnosed with autism than girls, the study found.

The research also found that vaccines are not to blame for autism in certain groups of children who may be more susceptible to getting autism - such as siblings of children with autism or kids of mothers who smoked during pregnancy.

"The idea that vaccines cause autism is still around despite our original and other well-conducted studies", Anders Hviid, the study's first author and an epidemiologist at the Staten Serum Institute in Copenhagen, told NPR. Not a single study afterward ever corroborated Wakefield's hypothesis at all, and by the time Lancet finally withdrew the study's publication twelve years later, the British medical community had concluded that Wakefield was a fraud.

A study has debunked a myth autism is linked to the MMR vaccination. The article was later retracted by the magazine which found elements of it to be incorrect and its lead author lost his medical license to practice in Britain, but it helped to embed anti-vaccination fears in parents that continue today.
