Summary 

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. A major change for the 2008 survey was in sampling areas; A number of both sampling and estimation areas were either rotated in and out of the sample, or combined into a single estimation domain. In total, the survey produced complete interviews for 25,948 children, and adequate provider data for 18,430 of those children.
