And the pro-disease people want you to still think that vaccines lead to autism, even though the link has been shown to be false over and over again. Take this study for instance:
Identification and Evaluation of Children With Autism Spectrum DisordersIf anything, maybe this graph indicates that vaccines also prevented autism, but only if they had thiomersal in them!

PDD-NOS means Pervasive Developmental Disorder-Not Otherwise Specified
The prevalence of autism and, more recently, ASDs is closely linked to a history of changing criteria and diagnostic categories. Autism first appeared as a separate entity with specific criteria in the DSM-III in 1980.17 In 1987, the Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised (DSM-III-R)38 listed broadened AD criteria and the new subthreshold category of PDD-NOS, both of which promoted inclusion of milder cases. Later, these changes received criticism for being too inclusive and for promoting overdiagnosis.39 The DSM-IV3 criteria published in 1994 reflected the result of years of analyses to reduce the overinclusiveness of the DSM-III-R criteria; however, it included AS for the first time, which, in effect, broadened the range of disorders. Studies have revealed that the DSM-IV criteria have better specificity (0.87) than DSM-III-R criteria.40 The DSM-IV-TR4 criteria for AD and AS are unchanged; however, the text description of PDD-NOS was edited slightly to increase specificity. Collaboration with European groups that worked on the revised International Statistical Classification of Diseases and Related Health Problems (10th edition)41 promoted better conformity between the 2 classification systems.
