Vaccines should always stay within a specific temperature range. Exposure to low or high temperatures can damage vaccines - and if that happens, a country may not have the vaccine supply it needs to immunize children. That’s why staff who handle and transport vaccines must know how to protect vaccines against unacceptable temperature excursions. This includes choosing and packing the appropriate coolant-packs and passive containers for specific transport routes. In this course, you will practice identifying where vaccines may be at risk, choosing the right coolant packs and passive containers for a variety of vaccine shipments, and finally, packing a passive container.
