More than a dozen states filed suit Tuesday against the Trump administration, challenging its decision to reverse federal childhood vaccine recommendations. The states argue the move illegally threatens public health by no longer recommending immunizations against diseases like the flu, rotavirus, hepatitis A, hepatitis B, meningitis, and RSV for all children.

Under the new guidance, these protections are now only recommended for high-risk groups or through "shared decision-making" with doctors. States, including Arizona and California, contend this policy ignores critical medical advice and will force them to increase spending to prevent outbreaks.
Arizona Attorney General Kris Mayes stated, "The health and safety of children across the country is not a political issue." The lawsuit highlights an ongoing conflict between Democratic-led states and the administration regarding federal public health policies, particularly under Health Secretary Robert F. Kennedy Jr. The complaint also alleges that Kennedy unlawfully replaced members of a vaccine advisory committee.
While states hold the authority to mandate vaccinations for schoolchildren, the CDC's recommendations significantly influence state regulations.
