一句话看懂
CDC reports 2,566 measles cases this year, highest in 35 years. Kindergarten vaccine exemptions hit record 4.2%, fueling outbreak risk.
背景
Measles was declared eliminated in the U.S. in 2000, but vaccination rates have been declining for years. For the 2025-2026 school year, the CDC reported that kindergarten MMR vaccination coverage fell to 92.4%, below the 95% threshold needed for herd immunity. Exemptions from school vaccine requirements rose to a record 4.2%, with most being non-medical. This has led to the worst measles outbreak in decades, with cases already exceeding the total for all of 2025.
