The National Immunization Survey

The National Immunization Survey (NIS) is sponsored by the National Immunization Program (NIP) and conducted by the National Center for Health Statistics (NCHS), Centers for Disease Control and Prevention.  The NIS is a list-assisted random-digit-dialing telephone survey that began data collection in April 1994 to monitor childhood immunization. In conjunction with the NIS, NCHS also conducts several other health surveys. 

The target population for the NIS is children between the ages of 19 and 35 months living in the United States at the time of the interview.  Data from the NIS are used to produce timely estimates of vaccination coverage rates for each of six recommended vaccines for the nation and for each of 78 Immunization Action Plan (IAP) areas, consisting of the 50 states, the District of Columbia, and 27 large urban areas.  The official estimates of vaccination coverage rates from the NIS are rates of being up-to-date with respect to the recommended numbers of doses of all recommended vaccines. These vaccines and their recommended numbers of doses are: diphtheria and tetanus toxoids and pertussis vaccine (DTP), 4 doses; poliovirus vaccine (polio), 3 doses; measles-containing vaccine (MCV), 1 dose; Haemophilus influenzae type b vaccine (Hib), 3 doses; hepatitis B vaccine (Hep B), 3 doses; and varicella zoster vaccine, 1 dose. In addition to these vaccines, interest focuses on coverage rates for vaccine series, including the 4:3:1:3 series (4 DTP, 3 polio, 1 MCV, and 3 Hib). 

The National Adult Immunization survey, sponsored by the National Immunization Program, monitors immunization rates for adults age 50 and older. Specifically, it asks about recent influenza vaccinations (flu shots) and, for those 65 and older, whether the respondent has ever had a pneumonia vaccination. The study also asks about reasons for getting or not getting vaccinations and plans for future vaccinations. Data were collected in the winter of 2003 and will be collected again in the winter of 2004. Data will be analyzed by staff at the National Immunization Program and will be used to help improve the delivery of vaccinations to the population age 50 and older. Special emphasis will be placed on immunizations for Hispanics, African Americans and other minorities in the U.S. The interview will be conducted in both English and Spanish. Interviews can be conducted with proxies if respondents are unable to respond for themselves.
