Here's how much vaccinations dropped among kindergartners during 2023 school year

Vaccinations among kindergartners in the United States saw a decline during the 2023-2024 school year, according to new data from the Centers for Disease Control and Prevention (CDC). 

The percentage of children vaccinated against key diseases like measles, mumps, rubella (MMR), and diphtheria, tetanus, and acellular pertussis (DTaP) dropped across the country, with many states reporting decreases in immunization rates for the second consecutive year.

Declining Vaccination Rates

The data revealed that vaccination coverage for the 2023-2024 school year was lower across all vaccines compared to the previous year. 

The percentage of children vaccinated ranged from 92.3% for DTaP to 92.7% for MMR. The year prior, during the 2022-2023 school year, 92.7% of children were vaccinated for DTaP and 93.1% were vaccinated for MMR.

Despite the slight decrease, the vast majority of children are still vaccinated against the diseases.

The number of kindergartners attending school without documentation of completing the MMR vaccine series was about 280,000 during the 2023-2024 school year.
