A major decade-long study has found there is no link between the Measles-Mumps-Rubella vaccine and autism, even among children with other risk factors for the disorder.

The study examined every child born in Denmark between 1999 and 2010, a group of more than 650,000.

The study found no increased risk of developing autism after getting the MMR vaccine, no clustering of autism cases among children who were given the vaccine, and no increase in the rate of autism among susceptible children who were given the vaccine.

Australian immunisation expert Professor Ian Frazer, who along with his team at the University of Queensland developed the vaccine for HPV, said the Danish study definitively confirms the findings of previous studies that vaccines do not cause autism.
