About the Data

Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.

Number of surveyed enrollees in kindergarten who received 4 or more doses of DTaP vaccine
Number of surveyed enrollees in kindergarten during the survey school year
Data Collection Frequency
Comparable Healthy People 2010 Objective
Adapted from HP2010 objective
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 2009-10 school year reflects vaccination coverage for kindergarteners as of start of the school year in 2009. States may collect and/or report data on selective antigens depending upon school entry requirements.

Caveats and Limitations
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).

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch

In 2013, the original baseline was revised from 95.0 (2007-2008) to 97.2 (2009-2010) because data prior to 2009-2010 could not be appropriately weighted and verified. The target was not revised.
