A poll released on Tuesday by the health research organization KFF found that adults in the United States who regularly obtain health advice from artificial intelligence chatbots are more likely to endorse false claims about vaccines, including the notion that shots cause autism. The survey, conducted earlier this year, included a nationally representative sample of U.S. adults and asked respondents about their use of AI tools for medical information as well as their beliefs regarding vaccine safety.
Respondents who reported frequent interaction with AI chatbots for health‑related questions were found to hold vaccine myths at higher rates than those who did not use such tools, according to the KFF poll. The findings were published on the organization’s website and have been cited as an early indicator of how emerging digital platforms may influence public attitudes toward immunizations.
Health officials have cautioned that the correlation does not prove that AI chatbot use causes misinformation, but they suggest that the platforms could reinforce existing doubts if users receive unverified or anecdotal advice. The poll adds to a growing body of research examining the relationship between technology use and health‑related beliefs in the United States.
Analysis: The results highlight a potential link between the consumption of AI‑generated health information and the persistence of vaccine myths, underscoring the need for clearer guidance on the use of automated advice tools. While the poll does not establish causality, it raises questions about the responsibility of developers and regulators in ensuring that chatbots provide accurate, evidence‑based content. Policymakers may consider measures such as transparency requirements or verification standards to mitigate the spread of false narratives that could undermine vaccination efforts.
