Preventing Freezing in Vaccine Carriers

As part of the project Optimize traveling exhibit featuring immunization supply chain innovations being developed and tested in different countries around the world, this banner and these handouts emphasize the importance of, and methods for, preventing accidental freezing of heat-sensitive products in vaccine carriers. They illustrate how different configurations of ice packs affect temperature and show typical temperature readings of vaccine carriers containing frozen ice packs, conditioned ice packs, cool water packs, and no ice.
