Understanding the Current State of Kindergarten Vaccination Coverage in the U.S.

by Jon Scaccia November 13, 2023

In recent years, public health professionals have closely monitored vaccination trends among school-aged children, especially kindergartners. The latest report from the Centers for Disease Control and Prevention (CDC) sheds light on the vaccination coverage and exemption rates for the 2022–23 school year in the United States. This data is crucial as it highlights the impact of the COVID-19 pandemic on routine childhood vaccinations and sets the stage for future public health strategies.

Vaccine Coverage: A Closer Look

The CDC report, titled “Coverage with Selected Vaccines and Exemption from School Vaccine Requirements Among Children in Kindergarten — United States, 2022–23 School Year,” provides a comprehensive overview of the current state of vaccination among kindergartners. Notably, the national coverage for state-required vaccines, such as measles, mumps, rubella (MMR), diphtheria, tetanus, and acellular pertussis vaccine (DTaP), poliovirus vaccine (polio), and varicella vaccine (VAR), remains near 93%. This figure is slightly lower than the pre-pandemic levels of about 95%.

State-by-State Variations

The report indicates a decrease in vaccination coverage across several states compared to the previous school year. For instance, MMR, DTaP, polio, and VAR coverage decreased in 29, 31, 28, and 25 states, respectively. These variations underscore the challenges different regions face in maintaining high vaccination rates.

Rising Exemption Rates: A Concern

One of the report’s key findings is the increase in exemption rates, which went up from 2.6% in the 2021–22 school year to 3.0% in 2022–23. This uptick in exemptions, seen in 41 states, is a concerning trend, as exemption rates exceeding 5% can hinder achieving optimal vaccination coverage. This increase poses a significant risk for outbreaks of vaccine-preventable diseases.

The Role of Nonmedical Exemptions

The report highlights that nonmedical exemptions account for a substantial portion of the increase in exemption rates. Understanding the reasons behind this rise is essential for developing targeted public health policies.

Implications for Public Health Practice

The data points to a critical need for concerted efforts to boost vaccination rates among kindergartners. Schools, healthcare providers, and immunization programs must collaborate to ensure timely vaccination before school entry. The CDC’s Let’s RISE initiative is a step towards addressing these challenges and aims to bring routine vaccination coverage back to pre-pandemic levels.

Challenges and Limitations

The report acknowledges several limitations, such as variations in state vaccine requirements, data collection methods, and representativeness issues. These factors must be considered when interpreting the data and formulating public health strategies.

Conclusion

The CDC’s report is a call to action for public health officials, educators, and healthcare providers to intensify efforts in promoting vaccinations. While the current coverage rates are commendable, there is room for improvement, especially in reducing exemption rates and addressing the barriers to vaccination.
