Another new study has found no link between the measles, mumps and rubella (MMR) vaccine and autism.

The study, which was published in the Annals of Internal Medicine in March 2019, examined 657,461 children born in Denmark between 1999 and 2010. About 95% got the MMR vaccine, and a total of 6,517 received an autism diagnosis.

Results concluded that the MMR vaccine doesn’t trigger autism in any kids, whether or not they were previously at risk for the disorder.

“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,” says the study. 

It adds that “no increased risk for autism after MMR vaccination was consistently observed in subgroups of children defined according to sibling history of autism, autism risk factors (based on a disease risk score) or other childhood vaccinations, or during specified time periods after vaccination.”

Although the number of individuals diagnosed with autism has increased in recent years, the Centers of Disease Control and Prevention (CDC) attributes this to the growth of knowledge and awareness over the years.

As more and more evidence is found to prove that autism and vaccination are not linked, experts are hoping to settle the minds of parents—and begin using their resources elsewhere to explore potential causes of this disorder.
