Cumulative and Peak Temperature Indicators

Dawn Smith of Temptime Corporation in the U.S. will develop a low-cost vial-level indicator device that provides a signal not only when vaccines have had brief but damaging exposure to high temperatures, but also have reached a cumulative heat exposure threshold. The integrated device would provide health care workers a comprehensive indication as to whether a vaccine has been damaged by heat and should therefore not be used.
