The Polio Transition1 Monitoring and Evaluation (M&E) Framework was designed to monitor progress towards achieving the strategic and operational outcomes of the post-2023 Strategic Action Plan on Polio Transition (2018– 2023), as outlined in the Global Vision to use polio investments to build strong, resilient and equitable health systems (the Global Vision), and regional strategic plans for the WHO African, Eastern Mediterranean and SouthEast Asia Regions. It aims to support an efficient and effective polio transition process through both process and outcome-based monitoring. The M&E Framework promotes accountability and strives for a harmonized approach to monitoring and evaluating the polio transition at the country, regional and global levels
