Pfizer's COVID-19 vaccine needs to be thawed from -94F and has to be used within five days: State officials scramble to carry out 'very complex' plans and overcome logistical ...

State health officials in the US are concerned the 'very complex' race to prepare for effective vaccine distribution could be thwarted by logistical challenges. While distribution is being handled on a federal level, state and local healthcare providers are responsible for storing and administering vaccines once delivered. Officials say they've had just weeks to prepare large-scale efforts after recently learning of specific storage requirements for vaccines.

Other vaccines currently being developed do not need to be stored as such a low temperature The US government plans to start vaccinating Americans next month if Pfizer has its COVID-19 vaccine approved by the FDA
