National MMR coverage has dropped 2% from the 2019-2021 school year to the 2022-2023 school year, which means approximately 250,000 kindergartners are at risk for measles infection around the country, according to the Centers for Disease Control and Prevention.
The 93.1% rate during the 2022–23 school is 2% lower than the 95% rate in the 2019-2020 school year and leaves measles coverage below the national target of 95% for the third consecutive year.
Doctors said this nationwide trend is a concerning backdrop to measles outbreaks in Florida and Philadelphia so far this year.
