About the National Immunization Survey-Teen (NIS-Teen)

The NIS-Teen is a national survey conducted every year by the Centers for Disease Control and Prevention (CDC) to assess vaccination coverage levels, or the percentage of people vaccinated, among adolescents 13-17 years of age. This study collects data by interviewing households in all 50 states, the District of Columbia, and smaller selected areas. The interviews are conducted by telephone, with households selected at random. To ensure the accuracy of vaccination coverage estimates, participant vaccination records are collected from healthcare providers by mail after the interview. The parents and guardians of eligible teens are asked during the telephone interview for consent to contact the adolescentsā€™ vaccination providers to verify their records.Ā Ā 

The NIS-Teen was established to provide an ongoing and consistent data set for analyzing vaccination coverage levels among adolescents in the United States and to share this information with interested public health partners. The NIS-Teen provides national and statewide estimates of vaccination coverage, including new vaccines as they are licensed and recommended for use. It also helps track progress towards the Healthy People 2030 goals.
