Overall, 95 per cent of the kids in the study got the vaccine.
A 1998 study in the prestigious medical journal Lancet suggested the vaccine was increasing autism in British children. He hopes the latest piece of evidence will reassure families with young children at risk of developing autism spectrum disorder that the vaccine will not increase that risk.
Measles can be avoided through vaccination, and 90 percent of Danish kids are every year, but in other nations fewer people are being vaccinated and the trajectory is on a downward spiral.
Also this week, the American Academy of Pediatrics wrote to Facebook, Google and Pinterest calling for the companies to do more to prevent the spread of misinformation about vaccines on their platforms.
"The paper reinforces the important public health message of maintaining high community vaccine coverage particularly in light of the lack of any association of MMR with childhood autism", Professor Leonard said.
The study released Monday looked at Danish children born between 1999 and 2010 and tracked vaccination status, autism diagnoses, sibling history of autism and other risk factors, reported The Washington Post.
"At this point, you've had 17 previous studies done in seven countries, three different continents, involving hundreds of thousands of children", Paul Offit, director of the Vaccine Education Center at Children's Hospital of Philadelphia, who was not involved in the new research, shared with CNN. Critics had complained that earlier efforts had failed to focus on the effects of the vaccine on kids at increased risk of autism, according to an editorial accompanying the new study. He was not involved with the new report.
They concluded that only one percent of the studied group went on to develop autism. "However, the anti-vaccine movement is not influenced by facts, by science or by logic, so I fear that another study demonstrating the safety of MMR vaccination will not sway those whose allegiance is not to reality, but to irrational arbitrary beliefs".
Children need two doses of the MMR vaccine - one at 12-15 months old, and then a second at 4-6 years old.
"Hopefully, our study can play a small part in turning the anti-vaccine tide", Hviid said.
