Danish researchers studied health profiles of over 600,000 children and confirmed that vaccines don’t cause autism.

A recent study reconfirmed the widespread consensus that vaccines don't increase a child's risk of autism. While numerous other studies of the past two decades have also reached this conclusion, the study published in the journal Annals of Internal Medicine is one of the most comprehensive of its kind. The researchers from Denmark's Statens Serum Institut analyzed routine health checkup data from 657,461 children, some of whom received the mumps, measles, and rubella (MMR) vaccination and others didn’t. They found that vaccinated kids were not more likely to be diagnosed with autism than non-vaccinated ones.

“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,” the authors concluded.

Although their findings agree with the large body of research on the topic, some experts say that neither the recently published paper nor future studies are likely to convince vaccine skeptics. “The question to my mind is should we continue to do more studies on this topic or is the uncertainty that is needed for having a researchable question gone at this point,” Emory University public health researcher Saad B. Omer told The Washington Post. “This new study isn’t going to change anyone’s mind.”Instead of trying to build a better case for vaccines, Omer said, we should require patients to opt-out of getting a vaccine instead of making them opt-in.
