Vaccines: Separating Fact From Fear - Do Vaccines Cause Chronic Illnesses?

Clinician: When parents ask me to prove that vaccines do not cause chronic illnesses, what information can I give them?

Paul A. Offit, MD: Well, certainly not all vaccines have been examined to see whether or not they cause all known chronic illnesses. But, I mean, anytime we have looked, we've been reassured. For example, we now know that vaccines are not a cause of diabetes; that vaccines are not a cause of multiple sclerosis; that vaccines are not a cause of inflammatory bowel disease; that vaccines are not a cause of autism; that vaccines are not a cause of sudden infant death syndrome. So I think, you know, when we've looked, we've been reassured.
