An ultracold storage facility capable of storing more than 1.6 million doses of COVID-19 vaccine has been completed at the University of Arizona.
The so-called "freezer farm" includes eight storage freezers to accommodate the first vaccines expected to be available in the U.S. – the Pfizer vaccine, which received emergency use authorization from the Food and Drug Administration on on Dec. 11, and another candidate produced by Moderna. Seven of the freezers are ultracold freezers that operate at minus 80 degrees Celsius (minus 112 degrees Fahrenheit), and the other one can provide storage at minus 20 C (minus 4 F). Two additional minus 20 C freezers are on the way.
