Summary

A KFF poll released on Tuesday found that frequent US adult users of AI chatbots for health advice are significantly more likely to believe anti-vaccine myths. The May survey of 2,480 US adults revealed that 35% of weekly AI health users believe MMR vaccines cause autism, compared to 29% of occasional users and 20% of non-users. Similarly, 29% of frequent AI users believe mRNA vaccines alter DNA, versus 20% of non-users, and 22% think the measles vaccine is more dangerous than the virus, against 15% of non-users. This correlation persists even after controlling for age, race, education, and political partisanship. The poll also noted a similar link between social media use for health and misinformation belief, with demographic differences in platform preference.

Key takeaway

For public health officials and AI developers addressing health misinformation, this poll highlights AI chatbots as a significant vector for anti-vaccine myths. You should prioritize developing robust content moderation and fact-checking mechanisms within AI models, especially for health-related queries. Consider targeted public awareness campaigns to educate users on critically evaluating AI-generated health advice, mitigating the spread of debunked claims like MMR vaccines causing autism.
