#Adult Immunity

The recent measles outbreak that originated in Texas earlier this year has rapidly expanded, with confirmed cases across the United States climbing to 483 by the end of March 2025. This alarming rise not only surpasses last year’s figures but raises critical questions regarding adult immunity, particularly for those unsure about their vaccination status. Notably, 93% of the current cases are tied to the Texas epidemic affecting regions including New Mexico and Oklahoma. This outbreak primarily involves individuals who are not vaccinated, prompting discussions on whether adults require a measles booster.
