KFF’s latest Tracking Poll on Health Information and Trust shows that larger shares of the public express uncertainty over common vaccine myths than definitive belief. The latest analysis shows which adults are consistent myth believers, consistent myth deniers, and those who fall in the “mixed middle.”
In a new column that analyzes recent KFF polling, Founding President and CEO Dr. Drew Altman concludes that only a sliver of the public hold definitive anti-science, anti-vaccine views, and are greatly outnumbered by the people who believe established science, with even more Americans stuck in a “muddled middle.” He writes, “when you see reports of social media engagement spiking about a health myth, don’t overreact. It’s more likely than not that it's a relatively…

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."
Two recent federal actions, including a memo about alleged COVID-19 vaccine deaths and settlements creating a “detransition clinic,” show how official actions can present uncertain or uncommon outcomes as representative and lend credibility to narratives that go beyond what evidence supports.
This brief summarizes the history, rationale, and policy issues related to the federal government's key vaccine injury compensation programs, known as the Vaccine Injury Compensation Program (VICP) and Countermeasures Injury Compensation Program (CICP).
State Medicaid and public health agencies both work to advance the health of their communities, often pursuing similar priorities and serving similar populations. This brief examines findings from KFF's 25th annual Medicaid budget survey, which asked state Medicaid directors about new or enhanced initiatives involving public health in FY 2025 or planned for FY 2026.
In a new column, Dr. Drew Altman, Founding President and CEO, dissects the MAHA “movement.” He writes: “There appear to be many MAHAs, not one. You can care about pesticides, or food additives, or vaccines, or child health, or corporate influence, or all of the above, to varying degrees.
