18% of American believe that vaccines can cause autism, 30% remain unsure and 52% of Americans don't think vaccines can cause autism, according to public opinion polling done after research linking vaccines to the condition was reported as fraudulent.
While 69% of respondents said they had heard about an association between vaccination and autism, 47% knew that the original Lancet study had been retracted, and that recently the research is reported as being fraudulent.
The poll also found that 86% of parents who have doubts about the vaccine said that their children were fully vaccinated, compared to 98% of parents who believe vaccines are safe, and that 92% of children are fully vaccinated.
The poll was conducted after news reports were published that said Andrew Wakefield, the lead researcher of the research linking autism to the MMR vaccine, had used faked data.
More than 20 studies since Wakefield's have disputed the association between vaccination and autism.
The online survey of 2,026 adults from Jan. 11 to 13 was done by Harris Interactive and HealthDay. (AP/Fox News, CNN, BMJ, WebMD)
