United States National Immunization Survey-Child 2005-2006

The National Immunization Survey is conducted by the National Center for Immunizations and Respiratory Diseases and the National Center for Health Statistics at the Centers for Disease Control and Prevention. It began in April 1994 in order to collect data on childhood immunization coverage. It uses a list-assisted random-digit-dialing telephone survey methodology of household respondents, and a mailed survey to children’s health care providers. The target population for the survey is children aged 19-35 months at the time of the interview, and the mail-in portion of the survey collects data on all current recommended vaccines and doses. Changes in 2005 included the selection by the CDC of the National Opinion Research Center at the University of Chicago to conduct the survey. In total, the survey produced complete interviews for 27,627 children, and adequate provider data for 17,563 of those children.
