AI Health-Advice Users More Prone to Vaccine Myths, Poll Finds

A KFF poll of 2,480 US adults finds that those who seek health information from AI chatbots at least weekly are more likely to endorse common anti-vaccine myths. For example, 35% of frequent AI health-users believe MMR vaccines have been proven to cause autism (vs 20% of non-users), and 29% believe mRNA vaccines can change DNA (vs 20% of non-users). About 22% think the measles vaccine is more dangerous than the measles virus (vs 15% non-users). The gaps persist after accounting for demographics and are linked to social-media health queries, underscoring concerns about AI-driven misinformation in health topics. The poll did not identify which AI models respondents used.
