Outcome data from one million children dispel vaccine-autism link
The largest review to date supports the value of MMRV vaccination, researchers say
An updated Cochrane review, covering more than 23 million children, confirms the efficacy of MMR vaccines and finds no evidence for a link with autism or a range of other conditions.
The review assessing vaccine effectiveness and potential harms adds another 74 studies to those canvased in the last update in 2012, and for the first time, includes data on use of MMR plus varicella vaccine and the tetravalent MMRV vaccine.
