About the National Data

Data

Data Source: Annual School Assessment Reports, CDC/NCIRD

Baseline: 94.7 percent of children enrolled in kindergarten received 2 or more doses of MMR for the 2018-19 school year

Target: 95.0 percent

Numerator

Number of surveyed enrollees in kindergarten who received 2 or more doses of MMR vaccine.

Denominator

Number of surveyed enrollees in kindergarten during the survey year.

Target-setting method

Maintain consistency with national programs, regulations, policies, or laws

Target-setting method justification

The target was selected to align with Vaccines for Children, Section 1928 of the Social Security Act, Section 317 of the Public Health Service Act, Advisory Committee on Immunization Practices (ACIP) Vaccine Recommendations immunization schedule for children, and the Immunization Program Operations Manual. Vaccination requirements for school entry have played a key role in reducing vaccine-preventable diseases in the United States. Maintaining high measles, mumps, and rubella (MMR) vaccination coverage among school-aged children, who are clustered together in a classroom setting, is essential for achieving herd immunity and preventing measles outbreaks.

Methodology

Methodology notes

Data reflect the median of state vaccination coverage estimates. Estimates are obtained by combining states' estimates and weighting the vaccine-specific coverage levels reported by states and territories to their respective birth cohorts. Data are provided for a school year and reflect vaccination status at entry into school. For example, vaccination for the 2016-17 school year reflects vaccination coverage for kindergarteners as of start of the school year in 2016. States may collect and/or report data on selective antigens depending upon school entry requirements. Sampling methodology vary by state, which is a major limitation (e.g., some states selected a random sample of kindergarten children and others conducted a census of all kindergarten children).

History

Comparable HP2020 objective

Modified, which includes core objectives that are continuing from Healthy People 2020 but underwent a change in measurement.

Changes between HP2020 and HP2030

This objective differs from Healthy People 2020 objective IID-10.2 in that the measure for objective IID-10.2 was the median of state vaccination coverage estimates, while the measure for this objective is based on the weighted coverage of each state. As a result, the Healthy people 2020 and 2030 data are not trendable.
