It’s been so rewarding to see the scientific progress being made toward understanding what causes autism and in developing better treatments for individuals with autism. While there are still a handful of parents who, in almost a religious way, cling to the notion that vaccines cause autism, the vast majority of parents and scientists have accepted what the data clearly show. There is no data to support an autism vaccine link. There never has been. Vaccines don’t cause autism.

A decade ago most agreed that we need to study vaccines in relation to autism. We had to reconcile the fact that the number of vaccines children were receiving was increasing, and at the same time, the number of children who were being diagnosed with autism also was on the rise. But fortunately this was a question that could be studied – and answered – by science. We looked at children who received vaccines and those who didn’t, or who received them on a different, slower schedule. There was no difference in their neurological outcomes. We’ve done multiple studies looking at the measles, mumps and rubella vaccination in relation to autism. We’ve looked at thimerosal, a mercury-based preservative, and its relation to autism. The studies are very clear; there is no relationship in the data between vaccines and autism.

It’s Time to Ask New Questions
If we ask the same questions we’ll get the same answers. We’ve asked the autism vaccine question over two dozen times and each time we get the same response; no relationship. We need to move on; We need to invest in studying genetics, the brain structures of children with autism, and environmental factors that may be playing a role.

Beware of Non-Evidence-Based Treatments
Parents can protect themselves and their children from expensive and ineffective treatments by learning to critically evaluate various claims. Before having their child begin any treatment, parents should question whether there is a coherent scientific rationale behind the intervention and whether it makes biological sense. They should also ask their health care practitioner whether the treatment has been proven effective and safe in objective scientific studies (with comparison to controls – i.e., patients who did not receive the treatment), and whether those studies have been published in well established, highly reputable, peer-reviewed medical journals. It is important to know that anyone can publish a study on the Internet or start a new journal.
