Developed jointly by WHO and UNICEF, the \"Immunization Coverage Data\" course will help all partners and staff working to support immunization with the knowledge needed to make the best use of available immunization coverage data. Before using data to make programmatic decisions, it is necessary to evaluate its quality and accurately interpret the data to understand the true situation. This course teaches how to evaluate data quality, recognize its limitations, and use data to make immunization programme decisions.
