DR CongoA health worker calls out to communities along the banks of the Congo River to bring their children to be immunized. He is also watching for children in passing canoes. The three-day national campaign aims to immunize all children under five. Throughout the country, warring factions have agreed to cease-fires for the duration of vaccination

Motorcyclists deliver vaccine, preserved in cold-storage boxes, 150 kilometres down jungle tracks to a remote health zone in eastern Congo. It is a risky journey: two weeks earlier a doctor conducting immunization surveys was shot on this road.© Sebastião Salgado

IndiaAfter all the children under five in a household have been immunized, health workers mark the house to show it has been covered, in a suburb of Ghaziabad, a city in Uttar Pradesh. Uttar Pradesh and Bihar are the only states in India where wild poliovirus is still circulating. In an all-out effort to eliminate the virus, entire districts are being blanketed with 'door-to-door' campaigns that literally target every house. © Sebastião Salgado
