Although multiple studies over the past 15 years have shown no link between the measlesmumpsrubella vaccine and autism spectrum disorders, many continue to associate the vaccine with autism. A new study examined whether the M-M-R vaccine was associated with an increased risk of autism in children whose older sibling already had an autism diagnosis.

Dr. Anjali Jain from the Lewin Group and co-authors studied more than 95 thousand children enrolled in a large commercial health plan, following them from birth to at least five years of age. These children all had an older sibling enrolled in the plan. The study appears in JAMA, Journal of the American Medical Association.
