Major study shows no link between MMR vaccine and autism

A large clinical study in Denmark has shown no link between the measles, mumps and rubella (MMR) vaccine and autism.

The study looked at 657,461 children born between 1999 and 2010, with follow-up from 1 year of age through to late 2013. Using Danish population registries, the researchers linked information on MMR vaccination, autism diagnoses, and related factors.

Adding to previous clinical study evidence, the authors conclude the data “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.”
