U.S. measles resurgence and vaccine-confidence crisis

CDC-reported cases reached 4,410 as of October 15, up 330 from the previous week; Pennsylvania reported 1,136 cases and five associated deaths as of October 9. Experts are raising concerns about mixed federal vaccine messaging and disputes over death reporting, even as local response funding is reported at roughly $100 million. Immunity gaps, infant risk, misinformation, and vaccination access remain central.
