The Immunization Data: Evidence for Action (IDEA) review is a global synthesis of existing evidence aimed at increasing the use of high-quality data to improve immunization coverage. Developed in partnership between PATH and the Pan American Health Organization (PAHO), the IDEA review draws on findings from nearly 550 documents—including published literature, working papers, project evaluations, and reports—distilled and prioritized by global immunization experts. The review identifies five proven strategies to improve data use and outlines how funders, policymakers, and program implementers can incorporate these best practices to improve the efficacy of state, regional, and national immunization programs. The resulting report provides a concise guide for global and public health practitioners, explaining what works to improve data quality and use, why it works, and how the immunization community can take evidence-based action to improve immunization outcomes around the world.
