National Immunization Survey-Teen (NIS-Teen)
: The National Immunization Survey -Teen (NIS-Teen) is sponsored by the National Center for Immunizations and Respiratory Diseases (NCIRD) and conducted by the National Center for Health Statistics (NCHS), Centers for Disease Control and Prevention. The NIS-Teen survey is conducted as an add-on to the NIS, which seeks to estimate vaccination coverage rates among 19 to 35 month-old children. NIS-Teen monitors vaccination coverage among persons aged 13-17 years. NIS-Teen identifies persons 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 if landline and, since 2011, cellular telephones. Survey respondents are parents or guardians of teens aged 13-17 years who provide information about their children's sociodemographic characteristics and vaccination providers. After receiving consent from respondents, questionnaires are mailed to all identified providers to obtain data from medical records, so that composite, provider-reported immunization histories can be analyzed.
Data Years Available
: Annually since 2006
: Sample survey - telephone interview (cell and landline) to participants followed by a mailed questionnaire to participants' immunization providers
: The official coverage estimates reported from the NIS-Teen are rates of being up-to-date with respect to the recommended numbers of doses of all recommended and catch-up vaccines (CDC 2012). These vaccines and their recommended numbers of doses are:
• Tetanus-diphtheria-acellular-pertussis vaccine (Tdap) – 1 dose;
• Meningococcal vaccine (MenACWY) – 1 dose;
• Human papillomavirus vaccine (HPV) – 3 doses;
• Measles/mumps/rubella vaccine (MMR) – 2 doses;
• Hepatitis B vaccine (Hep B) – 3 doses;
• Varicella zoster (chicken pox) vaccine, – 2 doses;
• Hepatitis A vaccine (Hep A), 2 doses; and
• Seasonal influenza vaccine – 1 dose annually.
: The target population for the NIS-Teen is persons aged 13 to 17 years living in non-institutionalized households in the United States at the time of the interview.
: The NIS-Teen survey is conducted as an add-on to the National Immunization Survey (NIS), which seeks to estimate vaccination coverage rates among 19 to 35 month-old children. The NIS uses a random digit dialing (RDD) telephone survey to identify households containing children aged 19 to 35 months and interviews the adult who is most knowledgeable about the child’s vaccinations. If such a household is identified and the NIS interview is completed, the household is then screened for the presence of 13 to 17 year-old children. Households that do not contain a 19 to 35 month old child are not administered the NIS interview but are immediately screened for the presence of 13 to 17 year-old children. If a household containing one or more children aged 13 to 17 years is identified, a 13 to 17 year-old child is randomly chosen and the adult who is most knowledgeable about the teen's vaccinations is interviewed. With consent of the teen's parent or guardian, the NIS-Teen also contacts (by mail) the teen's health care provider(s) to request information on vaccinations from the teen's medical records.
The NIS-Teen study has two parts:
1. A household telephone survey. This survey asks questions about immunizations for adolescents 13-17 years of age and requests parental permission for contacting adolescents' vaccination providers.
2. A survey of vaccination providers. This survey of doctors and other vaccination providers is conducted for study participants who have provided consent for this phase of the study.
Response rate and sample size
: In 2011, a total of 23,564 adolescents (12,328 males and 11,236 females) were included in the national estimates. The cellular phone household response rate was 22.4% and the landline household response rate was 57.2%. Only 54.6% (cellular phone) and 61.5% (landline) of those with completed household interviews also had adequate vaccination provider data.
