Many studies have looked at whether there is a relationship between vaccines and autism. The weight of the evidence indicates that vaccines are not associated with autism. But CDC knows that some parents and others may still have concerns about this issue. CDC is committed to protecting the health of children and to identifying the biological and environmental causes of autism and other developmental disabilities, so we will continue to study the role of vaccines.
