Madagascar faced an outbreak of polio between 2020 and 2023, leaving dozens of people paralyzed. In the face of this crisis, the government — alongside global health partners — launched seven sweeping vaccination campaigns across the country. In May, the outbreak was officially declared over.
The fight involved a symphony of people and organizations playing different roles — ranging from community health volunteers navigating remote terrain, to international agencies coordinating logistics and funding. They’ve faced enormous challenges, including hard-to-reach communities, vaccine misinformation, limited resources, frequent cyclones, and complicated data collection systems.
And the success remains fragile — with cuts to foreign aid threatening hard-won gains.
