More than a dozen states are taking action to protect children’s health — and they deserve our applause. After the Trump administration rolled back long-standing federal recommendations for routine childhood vaccinations, a coalition of states filed suit, arguing that the changes are unlawful and put kids at risk. The revised guidance would stop recommending several widely used vaccines for all children, limiting them instead to certain high-risk groups or leaving decisions to “shared decision-making.” Public health experts have warned that weakening these recommendations could increase the risk of outbreaks and undermine decades of progress in preventing serious diseases like hepatitis, meningitis, rotavirus, and the flu. These states are making a clear statement: children’s health should not be politicized. Vaccine recommendations must be grounded in science, medical expertise, and the well-being of families — not ideology. For generations, routine immunizations have protected children, reduced hospitalizations, and saved lives. When federal policy strays from established science, states have both the right and the responsibility to step in. Add your name to applaud these states for defending science, protecting children’s health, and standing up for evidence-based public health policies that keep families and communities safe.
