Cold chain technologies
Keeping temperature-sensitive health products properly cooled in extreme climates, over barely accessible roads, and in places with unreliable access to electricity is a constant challenge for developing-country health systems. Over the next decade, as new vaccines and essential medicines become available, it is critical that capacities are bolstered and appropriate tools are advanced to protect these products from damage, ensuring coverage and impact. Innovative cold chain technologies can help improve the reliability of vaccine distribution, reduce unnecessary vaccine wastage, enable new handling policies, and help strengthen the overall immunization system.
PATH is working to advance innovative technologies that help to more effectively store, monitor, and transport vaccines as well as other health care products at appropriate temperatures, especially in low-resource settings. Visit PATH’s website to learn more about its work on cold chain technologies.
