2008 National Immunization Survey Results - Vaccination Coverage Levels
The NIS is conducted by the Centers for Disease Control and Prevention to assess the vaccination coverage level among children 19 through 35 months of age and adolescents 13 through 17 years of age. NIS utilizes a random digit dial survey to collect immunization information from households with eligible participants. For completeness and verification, immunization data are also requested from vaccination providers with consent of parents.
