ROHM Cutting-edge Power Solutions for Traditional Freezers White Paper
■Some vaccines are highly sensitive to temperature variations and must be stored at ultra-low temperatures (ULT) from the point of manufacture until just before administration to the patient. The Pfizer COVID-19 vaccine, for example, initially required super-cold storage, with temperature maintained below -60 °C (-76 °F). In the manufacturing plant and associated warehouses, maintaining these temperatures is not difficult. But as the vaccines are transported out to distribution, and then to patients, maintaining those ultra-low temperatures becomes more difficult and more costly.
■The term "cold chain" refers to the supply chain that delivers products or materials that will be spoiled or destroyed if temperature varies beyond a prescribed range. Many food items, chemicals, and pharmaceuticals require tightly controlled "cold chain" logistics. The hardest part of a deep freeze temperature-controlled supply chain is the "last mile" problem. For vaccines that require extremely low temperature storage, expensive and technically complicated ultra-low temperature freezers are necessary at or near every point of vaccine administration, all over the world.
