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

The baseline total 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.
