Perhaps. Is autism caused by vaccines and only vaccines? Before vaccines, did autism exist? Should we stop vaccinating?
The problem is that (like AGW, for instance) some people take a theory and run with it, before all the facts are in. Vaccines may well be the cause, but only when combined with certain individual genetic factors, or they may be one cause out of several.

The sole purpose of vaccines has always been to spread disease.
The Salk vaccine literally created the polio epidemic of the early ‘50s.
Did anyone ever even hear of “autism” before mass vaccination of infants? Its insane.
