On January 5, 2026, the Centers for Disease Control and Prevention (CDC) issued a “Decision Memo” under the direction of Health and Human Services (HHS) Secretary Robert F. Kennedy, Jr.. This memo instructed the CDC to strip seven childhood vaccines of their universally recommended status. A coalition of states brought this law suit in response, alleging that the new vaccination schedule will damage public health by decreasing vaccine uptake and increasing rates of vaccine-preventable diseases, including by creating confusion, spreading misinformation contrary to established scientific evidence, and increasing vaccine hesitancy. Further, the complaint alleged the new schedule undermines Plaintiff States’ immunization, public health, and Medicaid programs and will cause them to incur substantial costs in preparing for, responding to, and treating higher incidences of vaccine-preventable illnesses and disease outbreaks. The states seek declaratory and injunctive relief to declare the schedule and the appointments of the Kennedy Appointees unlawful and to have them set aside.

This case is ongoing.
