Methodology Notes

54 of 56 CDC immunization information systems awardees (50 states, the District of Columbia, and other reporting areas) track immunizations administered to children and adolescents. "Other reporting areas" are defined as the following five cities: Houston, San Antonio, Chicago, Philadelphia, and New York City.

The following vaccines are included as age-appropriate immunizations for adolescents in this metric: Tdap/Td, HPV, meningococcal, seasonal influenza, pneumococcal, Hepatitis A, Hepatitis B, polio, MMR, and varicella.

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 denominator was removed since this objective is a count. In 2013, the objective statement was revised from "50 States plus District of Columbia" to "50 States, the District of Columbia, and other reporting areas" to reflect the 5 cities that operate separately from their state programs. In the methodology notes, "other reporting areas" are defined as the following five cities: Houston, San Antonio, Chicago, Philadelphia, and New York City. In 2013, the original baseline and baseline year were revised from 14 (2009) to 11 (2012) because some reporting areas were using the old reporting definition (2+ immunizations administered at any age) rather than the new reporting definition (2+ immunizations age-appropriate immunizations). The target was not revised.
