Calls to Action


Many studies have examined possible links between vaccination and increased prevalence of autism. This research has paid particular attention to the measles-mumps-rubella (MMR) vaccine, vaccines containing thimerosal and the total number of vaccines administered during early childhood or any one doctor’s visit. These studies have not found a link between vaccines and autism.

A study published today found that measles virus RNA was no more likely to be present in the bowel tissue of children with autism than that of typically developing children. Furthermore, GI symptom and autism onset were found to be unrelated to MMR vaccine timing. These findings refute an earlier report published in 1998 that indicated autism is associated with the measles virus vaccine.
