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 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 through 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 2014 through May 2016.
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 (3 or 4 doses depending on the vaccine type)
- ≥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.
