About the National Immunization Survey (NIS)
The NIS is a national survey conducted annually by the Centers for Disease Control and Prevention to assess immunization levels among pre-school children 19 through 35 months old. The NIS is the only population-based survey to provide national, state, local area, and territorial estimates of vaccination coverage among children aged 19-35 months in the United States. This study collects data by administering telephone surveys to randomly selected households. To ensure the accuracy and precision of the vaccination coverage estimates, immunization data for surveyed children are also collected through a mail survey of their pediatricians, family physicians, and other health care providers. The parents and guardians of eligible children are asked during the telephone interview for consent to contact the children’s vaccination providers. Types of immunizations, dates of administration, and additional data about facility characteristics are requested from immunization providers that are identified during the telephone survey of households. Data are weighted to be representative of the population of children 19-35 months of age, and are adjusted for multiple phone lines, mixed telephone lines (i.e., landline and cellular), household nonresponse, and the exclusion of phoneless households. There is another survey, called the NIS-Teen, which assesses immunization levels among teens 13-17 years of age.
The NIS provides national and state estimates of vaccination coverage, including new vaccines as they are licensed and recommended for use. The survey also tracks progress towards Healthy People 2020 goals.
Survey Sample
The survey assessed the immunization histories of approximately 15,000 children in the United States, aged 19 through 35 months with provider-reported vaccination records. These children were born January 2013 through May 2015.
Vaccines Included
The NIS collects information on the following vaccine series to assess the percent of children that are up to date with routinely recommended vaccinations:
- Diphtheria and tetanus toxoids and acellular pertussis vaccine (DTaP/DT/DTP)
- Poliovirus vaccine (Polio)
- Measles or Measles-Mumps-Rubella vaccine (MMR)
- Haemophilus influenzae type b vaccine (Hib)
- Hepatitis B vaccine (HepB)
- Varicella vaccine (Var)
- Pneumococcal conjugate vaccine (PCV)
- Rotavirus vaccine (ROT)
- Hepatitis A vaccine (HepA)
- Influenza vaccine (reported separately through NIS-Flu)
- 4:3:1:3:3:1:4 series
- ≥4 doses of DTaP
- ≥3 doses of Polio
- ≥1 dose of MMR
- ≥3 doses of Hib (or 4 depending on the product)
- ≥3 doses of HepB
- ≥1 dose of Var
- ≥4 doses of PCV
The 4:3:1:3:3:1:4 series is a marker reflecting coverage for seven key vaccine series combined. The 4:3:1:3:3:1:4 series is a representation of overall compliance for vaccines recommended by the Advisory Committee on Immunization Practices (ACIP) for children ages 19-35 months of age.

About the National Immunization Survey-Teen (NIS-Teen)
The NIS-Teen is a national survey conducted annually by the CDC to assess immunization levels for adolescents 13-17 years of age. This study collects data by interviewing households in all 50 States, the District of Columbia, and selected areas for oversampling. The interviews are conducted by telephone, with households selected at random. To ensure the accuracy and precision of the vaccination coverage estimates, immunization data for surveyed adolescents are also collected through a mail survey of their pediatricians, family physicians, and other health care providers. The parents and guardians of eligible adolescents are asked during the telephone interview for consent to contact the adolescents’ vaccination providers. Types of immunizations, dates of administration, and additional data about facility characteristics are requested from immunization providers that are identified during the telephone survey of households. The NIS-Teen’s estimates of adolescent vaccination coverage reflect a comparison of information provided by both surveyed households and immunization providers. There is another survey, called the NIS, that assesses immunization levels among children 19-35 months of age.
The NIS-Teen was established to provide an on-going, consistent data set for analyzing vaccination levels among adolescents in the United States (US) and to disseminate this information to interested public health partners. The NIS-Teen provides national and state estimates of vaccination coverage, including new vaccines as they are licensed and recommended for use. It also helps track progress towards the Healthy People 2020 goals.
Survey Sample
The survey assessed the immunization histories of nearly 20,000 adolescents aged 13-17 years in the US. These adolescents were born between January 1998 and February 2004. In Texas, 1,927 adolescents were surveyed for the 2016 NIS-Teen.
Vaccines Included
The following vaccine doses routinely recommended for adolescents were measured in the 2016 NIS-Teen.
- ≥1 Tetanus-diphtheria-pertussis (Tdap) vaccine.
- ≥1 dose of MenACWY or meningococcal-unknown type vaccine.
- ≥1 dose of HPV vaccine.1
- HPV vaccine Up-to-Date, either quadrivalent or bivalent.1
1 Percentage reported among females and males separately.
