chosen: Vaccines do not cause autism. There is no evidence to support this connection and many studies have shown that vaccines are not linked to autism. Some parents have incorrectly associated the rise in autism diagnoses with the increased vaccination of children and believe that the shot causes autism. However, the number of children who contracted measles, whooping cough and other childhood diseases has decreased significantly since immunization became more widely available. More research is needed to determine what causes autism, but it is believed to be a combination of genetic and environmental factors.
