Vaccines are extremely sensitive to temperature. They must remain between 2 and 8 degrees Celsius in order to remain viable. Outside of this temperature range, vaccines become less effective at preventing diseases. Because of this, the storage and handling of vaccines need careful attention. The equipment and devices used to ensure vaccines stay in the right temperature range are known as the “cold chain.” When vaccines are transported, stored in a refrigerator, or used in an immunization session, the cold chain keeps the temperature right. Significant investments have been made in updating cold chain equipment in many countries, but overall performance remains a significant concern.
With our new partner Bull City Learning, VillageReach is strengthening the vaccine cold chain in Malawi. Using human-centered design principles, we are creating an easy-to-use, interactive, digital manual on refrigerator maintenance and repair. By providing this tool for cold chain technicians, we hope to improve routine maintenance of essential equipment used to keep vaccines at the right temperatures.Read full story
