​AG Mayes led a multistate lawsuit challenging the Trump Administration’s radical overhaul of the nation’s childhood immunization schedule. The complaint, filed today, names Health and Human Services (HHS) Secretary Robert F. Kennedy, Jr., Acting Centers for Disease Control and Prevention (CDC) Director Jay Bhattacharya, and the CDC and HHS as defendants.

"For decades, the CDC’s childhood immunization schedule has been grounded in rigorous scientific evidence and has saved millions of lives. Secretary Kennedy and the Trump administration have thrown that science out the window. They fired qualified experts, replaced them with unqualified ideologues, and then concocted a dangerous new vaccine schedule that will put Arizona’s children—and children across the country—at risk of contracting diseases that are preventable." – AG Mayes
