Measles vaccine rates dropped in 80% of U.S. counties post-pandemic, raising outbreak risks.

Johns Hopkins University study shows measles vaccination rates dropped in nearly 80% of U.S. counties after the COVID-19 pandemic, with significant declines in states like Texas and Kansas experiencing outbreaks. Health experts warn that community-level vaccination rates need to be at 95% to prevent outbreaks, but many counties fell below this threshold, leading to increased measles cases.
