A new Kaiser Family Foundation brief tracks how states are reshaping vaccine policies amid shifting federal guidance. As of Sept. 22, 2025, 26 states had implemented or announced updates expanding access to COVID-19 and other vaccines beyond federal limits. The analysis highlights a sharp partisan divide: Democratic governors lead 23 of those 26 states. The findings suggest vaccine access may increasingly vary by state, reflecting broader political polarization and mirroring national divides in public opinion over vaccination and public health policy.
