WHO/Umit Kartoglu

Health workers return after an immunization programme in Indonesia’s Kalimantan island, many parts of which can be reached only by boat. By providing a clear indication of the quality of vaccines at all times, VVM offers the opportunity for successful immunization in remote areas, even in the absence of a reliable cold chain. Over the next 10 years, 1.5 billion more vaccine doses can be delivered to remote locations.
