Health officials and all the leading medical authorities insist vaccines don’t cause autism, but more than half of Americans are still unsure whether they do, a new poll finds.

Fifty-two percent of respondents to a Gallup poll released Friday said they don’t know whether certain vaccines cause autism in children, while 41 percent said they don’t and 6 percent said they do.
