The National Immunization Survey is part of the National Center for Health Statistics at the Centers for Disease Control and Prevention. It is divided into two components: a randomized household telephone survey and a mailed survey to providers. In addition to gathering information on the immunization coverage of children, teens and adults in the United States, it is used to track progress towards the Healthy People 2010 goals related to vaccines.
Users can link to published reports and tables about vaccination coverage at the national or state level. Full data sets are are also available to download as zip files, SAS input statements or R input statements. By clicking on “National Immunization Program- Immunization Coverage in the United States” on the homepage, users can download tables and maps. The tables can be downloaded as Excel files or HTML files and allow data to be viewed by: age; race/ ethnicity; urbanicity; WIC and poverty status; provider type and characteristics; and other selected socio-demographic variables. The NIS provides information on the national and state level.
Public use data files are available for every year since 1995. While vaccination coverage is estimated each quarter, the site does not specify when it is updated with new information. The sample population is considered nationally representative. The most recent data is available from 2009.
