Update on Common Vaccine Myths: People Without a Trusted Health Care Provider Are More Likely to Endorse False Vaccine Claims

This poll looks at exposure to and belief in several vaccine myths and finds that people without a trusted health care provider, and those who regularly use social media or AI for health information, are generally more likely than others to belief the false claims. It also analyzes belief across vaccine myths, showing the share of the public that are consistent myth believers, consistent myth deniers, and those who land in the “mixed middle.”

THE MIDTERMS

KFF Health Tracking Poll: MAHA and the Midterms

Chemical food additive and pesticide concerns associated with the Make America Health Again (MAHA) movement are shared broadly across the public. But when it comes to voters, health care costs are a higher priority and bigger motivator, even among MAHA supporters, a new KFF Health Tracking Poll finds. When asked to identify their most important health priority for government to address, far more MAHA-supporting voters identify lowering the cost of health care (42%) than other issues more closely associated with the movement.

KFF/New York Times Survey of Immigrants

KFF-New York Times Survey: Immigrants Report Rising Fear, Negative Economic and Health Impacts, and Changing Political Views During the First Year of President Trump’s Second Term

The 2025 Survey of Immigrants, a partnership between KFF and The New York Times, takes an in-depth look at the experiences of immigrants during the first year of President Trump’s second term, including their worries related to increased immigration enforcement, their health and economic wellbeing, and the political views and preferences of immigrant voters. The survey paints a portrait of families under strain — where fear of detention and economic instability are negatively impacting immigrants’ health and reshaping immigrant families’ daily lives and views of U.S. political parties.
