Vaccines and Immunization

CDC data show the U.S. has recorded more than 1,800 measles cases so far in 2025, the most in over 30 years, with infections confirmed in at least 39 states. The largest outbreak was in West Texas with more than 760 cases and two pediatric deaths among unvaccinated children before the state declared it over in August; New Mexico reported one adult death. Health officials cite declining MMR coverage among kindergarteners (about 92.7% in 2023–24 vs. 95.2% in 2019–20), while HHS Secretary Robert F. Kennedy Jr. publicly urged measles vaccination though opposed mandates.
