No Association Found Between Measles, Mumps, Rubella Vaccine and Autism
A new study examined whether or not the MMR vaccine was associated with an increased risk of ASD, especially in children whose older sibling already had an autism diagnosis.
Researchers reviewed the records of more than 95,000 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. Researchers were particularly interested in children whose older sibling had an ASD diagnosis since that puts the younger child at a higher risk for ASD.
The results found no evidence of an association between the MMR vaccine and ASD, regardless of whether the older sibling had ASD, confirming the safety of MMR vaccination.
