Public‑health researchers reported sustained measles circulation in the U.S., with over 1,300 cases so far this year and ongoing outbreaks in multiple states, reversing two decades of elimination status. The analysis cites falling MMR coverage below herd‑immunity thresholds and warns that regional gaps have enabled continuous transmission since 2025. Separately, controversy swirled around the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices (ACIP) after court action and social‑media claims. A federal judge issued a temporary injunction that halted votes by ACIP appointees selected by Health Secretary Robert F. Kennedy Jr., raising questions about the panel’s composition and the future of vaccine guidance. Together, the epidemiologic data and governance dispute amplify uncertainty around national vaccine policy and implementation.
