“Measles is a preventable illness due to vaccination, however low protection in weak communities is fueling these outbreaks,” mentioned Dr. Daniel Salas, Govt Supervisor of PAHO’s Particular Programme on Complete Immunization. “Strengthening immunization—realizing that the measles vaccine is secure and extremely efficient—is important to guard hundreds of thousands throughout the Americas.”
Nearly all of circumstances have been reported in Canada (4,849 circumstances, 1 demise), Mexico (4,553 circumstances, 19 deaths), and the US (1,454 circumstances, 3 deaths), which collectively account for 96% of the regional complete.

Though regional measles vaccine protection improved barely in 2024—reaching 89% for the primary dose and 79% for the second—solely a small fraction of nations met the 95% protection required to forestall outbreaks.
The group recommends instant motion, together with nationwide campaigns to vaccinate a minimum of 95% of the inhabitants with two doses, fast immunization of contacts of confirmed circumstances, intensified vaccination in outbreak zones, and the vaccination of vacationers to affected areas.
