KFF Tracking Poll on Health Information and Trust: Update on Common Vaccine Myths

Uncertainty about common vaccine myths remains widespread despite relatively few U.S. adults fully believing false claims, highlighting continued vulnerability to health misinformation. KFF found that at least half of adults classified each false claim as "probably true" or "probably false," while fewer than one in ten expressed firm belief in any individual myth.

Belief in misinformation was more common among people without a trusted health care provider, those who regularly use social media or AI for health information, and parents who delay or skip childhood vaccinations.

The findings suggest strengthening trusted health communication may help reduce uncertainty and improve vaccine confidence. Read the full report from KFF here.
