Developed by UNICEF and WHO, the Immunization eLearning Initiative provides all immunization staff with access to training in areas deemed vital to the advancement of the Global Vaccine Action Plan and its vision that everyone live a life free from vaccine preventable disease.

This Immunization Coverage Data course will help staff to make the best use of available data. With immunization coverage data available in all regions, it can provide a valuable measure of immunization status. But before you use immunization coverage data to make programmatic decisions, you need to evaluate its quality and accurately interpret the data to understand the true situation. After completing this course, you will understand how to evaluate data quality, recognize its limitations, and use data to make immunization programme decisions.
