Methodology Notes

The National Immunization Survey-Teen (NIS-Teen) collects vaccination information for adolescents aged 13–17 years in the 50 states, the District of Columbia, selected areas, and the U.S. Virgin Islands, using a random-digit–dialed sample of landline and, starting in 2011, cellular telephone numbers. Parent/guardian respondents provide vaccination and sociodemographic information on adolescents in their care. After the parent/guardian grants permission to contact their child's vaccination provider, a questionnaire is mailed to that provider to obtain a vaccination history from the medical record. Data for this measure are restricted to adolescents aged 13–15 and weighted to represent the population of adolescents age 13–15, with adjustments for households with multiple telephone lines and mixed telephone use (landline and cellular), household nonresponse, and exclusion of households without telephone service.

In 2005, the Advisory Committee on Immunization Practices (ACIP) recommended 1) a routine 2-dose varicella vaccination program for children, with the first dose administered at age 12–15 months and the second dose at age 4–6 years; and 2) a second dose catch-up varicella vaccination for children, adolescents, and adults who previously had received 1 dose.

This measure tracks the proportion of adolescents aged 13–15 years receiving at least 2 doses of the varicella vaccine among those who have not had varicella disease.

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 2014, the data source name was revised to the “National Immunization Survey (NIS) – Teen” to distinguish this survey from the “National Immunization Survey (NIS),” which samples children between the ages of 19 and 35 months. Neither the data nor the target were revised.
