Historical Measles Trends
- Before 1963, the U.S. had about 500,000 reported measles cases and 500 measles deaths per year. There were epidemic cycles every two to three years. However, experts estimate that the actual number of infections was 3-4 million annually.
- Measles was common in children:
- More than half of children had measles by age 6.
- More than 9 in 10 had it by age 15.
- After the measles vaccine was introduced in 1963, cases dropped by more than 95 percent, and the two-to-three-year epidemic cycles stopped.
- Between 1985 and 1988, two-thirds of school-aged measles cases were in children who had received only one dose of the vaccine.
- In 1989, the CDC began recommending a second MMR dose to provide better protection.
- From 2000 to 2024, most cases were related to international travel.
