The NIS provides current, population-based, state and local area estimates of vaccination coverage among children and teens using a standard survey methodology. The surveys collect data through telephone interviews with parents or guardians in all 50 states, the District of Columbia, and some U.S. territories.

Welcome NIS-Child and NIS-Teen vaccination providers

You have a chance to take part in an important national public health program that provides vaccination coverage information to help guide the nation's health policies.

Thank you for helping the National Immunization Surveys (NIS), including the NIS-Child and NIS-Teen, provide accurate information about childhood and adolescent vaccinations. These surveys could not be completed without your dedicated support.

How surveys are conducted

Since 1994, the NIS-Child, conducted by the Centers for Disease Control and Prevention (CDC), has provided the public with important information about childhood vaccinations and related health issues. In 2006, CDC started the NIS-Teen to provide similar information about vaccinations received by adolescents. The NIS-Child and NIS-Teen include a household interview and a mail survey to the child's vaccination provider(s). In the household survey, a parent or guardian provides information about the age-eligible child or adolescent. After the parent or guardian grants permission to contact their child's or teen's vaccination provider(s), the Immunization History Questionnaire is mailed to you to obtain a vaccination history from the child's or teen's medical records. This is an essential part of the NIS-Child and NIS-Teen for monitoring vaccination coverage rates. The information you provide on the Immunization History Questionnaire (IHQ) is very important for CDC to track accurate vaccination coverage at national, state, and selected local levels.
