Rising measles cases and falling vaccination rates put states at risk of outbreaks and the budget strains that come with them. Almost half of all measles cases in the U.S. this century have occurred since January 2025 - and counting. As a result, we're poised to lose our 25-year measles elimination status later this year.

 

This is a pivotal moment in the fight against measles. Measles requires an immunity level of 92-94% to prevent spread and stop an outbreak. Lower rates leave more people in proximity vulnerable to illness and economic burdens. Also at risk: the Vaccines for Children (VFC) program, which provides vaccines at no cost to children whose parents or guardians may not be able to afford them. Reductions or eliminations in funding would further jeopardize access for children and protections for those too young to be vaccinated.
