Still another large, well-designed study has confirmed that the childhood vaccine against measles, mumps, and rubella (MMR) does not increase the risk of autism.
Published in the Annals of Internal Medicine in March 2019, the study followed more than 650,000 children born between 1999 and 2010 in Denmark, 1 percent of whom developed autism, and found that those who got the MMR vaccine were not more likely to develop the disorder than their unvaccinated counterparts.
Moreover, the vaccine did not increase the risk of autism in children who had autistic siblings or other risk factors for autism. There is no scientific evidence that vaccines can cause autism.
As a result of successful immunization, measles was declared eliminated in the U.S. in 2000. However, myths and misinformation have led many parents to forgo the vaccination of their children, resulting in several measles outbreaks in the U.S., including at least five in the first three months of 2019.
