"And we know that measles, mumps and rubella vaccination coverage for kindergarteners is the lowest it has been in over a decade," Peacock said.
Nearly a quarter of a million kindergartners are potentially vulnerable to measles due to a dip in vaccination coverage during the pandemic, according to the Centers for Disease Control and Prevention.
Kindergarteners are required to be vaccinated against measles, mumps and rubella, chickenpox, polio, and diphtheria, tetanus and pertussis.
The vaccination rates for measles, mumps and rubella was 93.5% during the 2021-2022 school year, below the target coverage of 95% to prevent outbreaks.
The CDC report looked at whether the kindergarteners had received the second dose of their measles, mumps and rubella vaccine.
