US Faces $7.8 Billion Measles Risk as Vaccination Rates Decline, Study Finds

A study estimates a sustained drop in childhood MMR vaccination could cost the U.S. about $7.8 billion in measles outbreak-related expenses over five years; officials report more than 1,700 measles cases this year.

A new study warns that sustained declines in childhood MMR vaccination could lead to substantially higher measles cases and costs in the United States. The researchers estimate about $7.8 billion in outbreak-related costs over five years and report that measles outbreaks in 2025 generated $244 million. The study was published in the Proceedings of the National Academy of Sciences and appears alongside reports of more than 1,700 measles cases this year and changes to federal vaccine advisory staffing. Key details: - The 2025 outbreaks were estimated to cost about $244 million, or roughly $104,600 per case, mainly from containment efforts and lost productivity. - A modeled 1% annual decline in MMR uptake among young children would raise cases to more than 17,000 a year by 2030, with more than 4,000 hospitalizations and dozens of deaths. - Annual economic costs could reach about $1.5 billion by 2030 under that scenario, more than six times current levels. - The authors note their estimates likely understate total impacts because they do not fully capture long-term complications or the economic cost of deaths. Summary: The study links modest declines in vaccination coverage to rapidly rising illness and economic burden, with concentrated risk in areas that already have lower vaccination. Undetermined at this time.
