Immunization Data: Evidence for Action. Realist Review of What Works to Improve Data Use for Immunization, Evidence from Low- and Middle-Income Countries

ABSTRACT

Data quality is a cornerstone of well-functioning health systems. Sound and reliable information enables better resource allocation, more targeted care, policy development, and implementation, and more effective health education and training. Calls to improve the quality and use of data feature prominently in several national plans of action and in global strategies like the Global Vaccine Action Plan. The goal of the Immunization Data Evidence for Action (IDEA) project is to identify, review, synthesize, and disseminate what works to improve the use of immunization data and why it works.
