We’re two decades past the publication of the now-retracted study that claimed to show a link between autism and the MMR vaccine, but we can’t seem to shake its effects. The physician who lead the study committed fraud and has had his medical license revoked. Numerous studies have demonstrated the complete lack of a link between vaccines and autism. Yet many people are still concerned.

Now, in the face of some of the worst outbreaks the world has seen in recent years, Danish researchers have published one of the largest studies of autism and MMR to date. Its finding should come as no surprise: there’s no link.

The results, published in the Annals of Internal Medicine, are the result of following 657,461 children born between 1999 and 2010. Researchers followed up with those children starting at one year of age and continued through August 31, 2013. The massive size of the dataset allowed the study authors to control for various factors like age, sex, sibling history of autism, and other autism risk factors. In the end, 6,517 children received an autism diagnosis—and the risk was exactly the same regardless of whether they got the MMR vaccine. What’s more, as an editorial in the same journal issue points out, they showed that there was no association between when a child got vaccinated and when they got an autism diagnosis, further undermining any causal link.

Vaccinate your fucking children.
