Polio Today, The Cold Chain

Today almost 60% of vaccines are thrown away because of doubts about their potency after breaks in the cold chain and possible damage from exposure to high temperatures. –World Health Organization, 1996

A vaccine manufacturing site and the children needing immunization may be separated by thousands of miles. And over that distance, the vaccine must be maintained at a temperature just above freezing. National Immunization Days require a network of freezers, refrigerators, and cold boxes across the world’s jungles and deserts.

“Motor bikes developed for use by farmers in the Australian bush have been adapted to meet the specifications needed for vaccine delivery. Elsewhere, health workers make use of horses and even dug-out canoes to ensure that vaccine gets through to children in the remotest health system.”
—World Health Organization, 1996
