Largest Study of Its Kind Finds No Link between Vaccine and Autism

A large Danish study, published March 5, 2019, in the Annals of Internal Medicine, added "significant additional statistical power" to the claims that the MMR vaccine (for measles, mumps, and rubella) does not cause autism. Vaccine hesitancy is listed as one of the World Health Organization's 10 threats to global health for the first time this year (see HRC Alerts, January 30, 2019). The study's authors analyzed data on 657,461 children born in Denmark between 1999 and 2010 for information on MMR vaccination and autism diagnoses, among other factors.
