Sample survey: telephone interview (cell only) to parent or guardian of a child 19-35 months followed by a mailed questionnaire to child's immunization providers.
The National Immunization Surveys (NIS) are a group of telephone surveys used to monitor vaccination coverage among children and teens. The surveys are sponsored by the Centers for Disease Control and Prevention, National Center for Immunization and Respiratory Diseases (CDC, NCIRD) and conducted by the National Opinion Research Center (NORC). The NIS-Child is a random-digit-dialing telephone survey of parents or guardians of children ages 19 to 35 months, followed by a mailed survey to the children's immunization providers. Data from the NIS-Child are used to produce current, population-based, state and local area estimates of vaccination coverage for all childhood vaccinations recommended by the Advisory Committee on Immunization Practices (ACIP). Children are classified as being up to date based on the ACIP-recommended numbers of doses for each vaccine.
Population Covered
The target population for the NIS-Child is children between the ages of 19 and 35 months living in the United States at the time of the interview.
