In the Boucle du Mouhoun region, community health workers reached isolated and displaced families by bicycle, traveling 10–15 km per day with vaccines carried in UNICEF-supported cold boxes. During the November 2025 campaign, one team alone vaccinated 1,499 children, helping the area reach 95% coverage despite insecurity and access constraints. By combining persistence, local trust, and community dialogue, frontline workers turned logistical barriers into a successful, community-driven response to protect children from polio.
