DENMARK — A new decade-long study of more than half a million children found that the measles vaccine does not increase the risk of autism.
Researchers from Denmark followed 657,461 children born in Denmark between 1999 and 2010. Some of the children received the measles, mumps and rubella vaccine and some did not.
Of those children, 6,517 were diagnosed with autism, but researchers found no increased risk of autism in children who had the MMR vaccine. There was also no evidence that the vaccine triggered autism in children at higher risk for the disease.
“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 researchers wrote.
