Objective:

To assess the relationship between having a trusted health care provider and beliefs in vaccine myths, as well as the impact of social media and AI usage on these beliefs.

Approach:
  • Survey Methodology: Conducted by KFF, the survey included 2,480 U.S. adults and was carried out online and by telephone from May 7-31, 2026.
Key Findings:
  • Individuals without a trusted health care provider are more likely to believe vaccine myths.
  • 39% of those without a trusted provider believe MMR vaccines cause autism, compared to 24% with a trusted provider.
  • 37% of frequent social media users and 35% of AI users endorse the autism myth, compared to 16% and 20% of non-users, respectively.
  • Parents who delay or skip vaccines are more likely to believe false claims about vaccines compared to those who are up to date.
Interpretation:

Limitations:
  • The survey's margin of sampling error is plus or minus three percentage points for the full sample.
  • Results based on subgroups may have a higher margin of error.
