Background: Since inception, Immunization Information Systems (IIS) have evolved as a critical tool for assessing the state-of-immunizations in the
Population: State and local IIS that receive 317 grant funds.
Project Description: Grantees are required to submit assessment data through an IIS Annual Report (IISAR) to CDC. This project studies IISAR data by simultaneously examining how dynamics in one or more assessment areas may impact changes in other areas. The project examines the impact of various indicators, such as public-private provider participation, data access by user groups, and timeliness and completeness of data on participation and vaccine series coverage for different age groups. Data are analyzed for a single time period. Interactive data display tools illustrate data dynamics over time and across indicators.
Results/Lessons Learned: Preliminary analysis demonstrates IIS data can be efficiently used to better understand IIS challenges and trends. The final results will indicate whether (1) IISAR data alone are sufficient to understand dynamics within individual IIS or at a national level or (2) additional studies are needed.
