According to the U. S. Centers for Disease Control and Prevention, about 110 children in the United States is an autistic spectrum disorder, which is part of a group of developmental disorders that can cause significant social, communication and behavioral problems.Interactive / HealthDay Harris Poll was conducted online in the United States from January 11-13, 2026 and included adults over 18 years. The data for age, sex, race / ethnicity, education, region and household income were weighted where necessary to bring them into line with their actual proportions in the population.
Safety of the vaccine was a major concern for many parents after the study was published in 1998, now led by disgraced British doctor Andrew Wakefield, who concluded that the MMR vaccine caused autism. The newspaper that originally published the study, The Lancet, has since withdrawn the paper and Wakefield was recently banned from practicing medicine in Great Britain.
Barbara Loe Fisher, co-founder and president of the National Information Center Vaccine, which supports more research on vaccine safety, said that autism is only a concern related to vaccines.
But only half knew that the original Lancet study by Wakefield and others had been returned, and that some of these studies is now considered fraudulent.
However, the retraction and allegations of fraud do not seem to have influenced public perception. Among those who had followed the news in Wakefield, only 35 % think that the vaccine-autism theory, compared to 65 % that has not kept up to date on the latest developments.
The survey also found that parents who have doubts about the vaccine were less likely to say that their children were fully vaccinated , compared to 98 % of parents who believe in the safety of vaccines.
Sixteen % of adults surveyed said they knew at least one family whose children had not received all recommended vaccines due to concerns about autism. A quarter of those who believed that the vaccine theory of autism that they knew at least one family that was not fully vaccinated their children.
Only a slim majority of 52 % of Americans think vaccines cause autism Don t, a new survey Harris Interactive / HealthDay poll found.
However, the %age of fully vaccinated children remains high at 92 %, according to the survey.
Parents have legitimate questions about the risks of vaccines and want better vaccine science to define the risks for their child, he said. This concern long before the debate over vaccines and autism. National Vaccine Childhood Injury Law in 1986 was approved by Congress, in part to respond to these concerns, but did not work.

In recent weeks, another major British medical journal, the British Medical Journal has published a series of articles denouncing the deliberate fraud by Wakefield in his handling of the research that formed the basis for the 1998 study.
The study involved mice genetically engineered by Thompson to develop an MS-like disease called .
In the new survey, Harris Interactive / HealthDay poll, 69 % of respondents said they had heard the theory that certain vaccines can cause autism.
It seems reasonable to argue for the vaccination and I think this will increase with the revelation that many of these things was based on fraud or bad science, said Dr. Kenneth Bromberg, chairman of pediatrics and director of the Center for vaccine research at the ‘Brooklyn Hospital Center in New York.
Forty % is a huge amount and this is something relatively new [accusations of fraud], that’s great that they have heard of him.
But it still means that half the population does not, Taylor says.
