There’s strong new evidence that a common childhood vaccine is safe.
A large study released Monday finds no evidence that the vaccine that protects against measles, mumps and rubella increases the risk of autism. The study of children born in Denmark is one of the largest ever of the MMR vaccine.
“The study strongly supports that MMR vaccination does not increase the risk for autism,” the authors write in the Annals of Internal Medicine. “We believe our results offer reassurance and provide reliable data.”
The study’s first author, epidemiologist Anders Hviid of the Staten Serum Institute in Copenhagen, added in an email: “MMR does not cause autism.”
