Immunization registries are confidential, computerized information systems that collect and consolidate vaccination data from multiple health-care providers. This report summarizes data from CDC's 2005 Immunization Information System Annual Report (IISAR), a survey of grantees in 50 states, five cities, and the District of Columbia. The data indicated that approximately 56% of U.S. children aged <6 years participated in an IIS, an increase from 48% in 2004.
Use Cases
