Another study finds no link between autism and MMR vaccine.
In the current study, researchers examined data on 657,461 children. During this time, 6,517 kids were diagnosed with autism.
Kids who got the MMR vaccine were seven percent less likely to develop autism than children who didn't get vaccinated, researchers report in the Annals of Internal Medicine.

Measurements: Danish population registries were used to link information on MMR vaccination, autism diagnoses, other childhood vaccines, sibling history of autism, and autism risk factors to children in the cohort. Survival analysis of the time to autism diagnosis with Cox proportional hazards regression was used to estimate hazard ratios of autism according to MMR vaccination status, with adjustment for age, birth year, sex, other childhood vaccines, sibling history of autism, and autism risk factors (based on a disease risk score).
