    • Description:
      Immunizations have proven to be an important tool for public health and for reducing the impact of vaccine preventable diseases. To realize the maximum benefits of immunizations, a coordinated effort between public policy, health care providers and health systems is required to increase vaccination coverage and to ensure high-quality data are available to inform clinical and public health interventions. Immunization information systems (IIS) are confidential, population-based, computerized databases that record all immunization doses administered by participating providers to persons residing within a given geopolitical area. The key output of an IIS is high-quality data for use in targeting and monitoring immunization program activities and providing clinical decision support at the point of care. To be truly effective, IISs need to form a nationwide network and repository of immunization data. Since the early 2000s Centers for Disease Control and Prevention has made strides to help IIS move toward a nationwide network through efforts focused on improving infrastructure and functionality, such as the IIS Minimum Functional Standards, and the IIS Annual Report, a self-reported data collection of IIS progress toward achieving the functional standards. While these efforts have helped immunization programs achieve more functional standards, there is a need to shift focus from infrastructure and functionality improvements to high data quality through objective measurement of IIS performance and evaluating critical outcomes. Additionally, realizing the vision of a nationwide repository of high-quality immunization data requires tackling the many challenges that impact data quality and availability including those related to policy, data sharing, data use, aging IIS technology, sustainability, and participation in the IIS. This paper describes the current state of IIS in the United States, critical challenges impacting the quality of data in IIS, and potential components of a future IIS model to address these challenges.
