Pfizer’s vaccine must be kept at –70 degrees C (–94 degrees F)—a much greater challenge. The ultralow chain, the deep freeze, is the one at –70 degrees C. There’s the “frozen” chain, at –20 degrees C, which is more like a regular freezer. Pharmacy chain distribution centers may have that storage—the “sub-80 freezers” [boxes that can refrigerate down to –86 degrees C]. Of course, there will be questions of equity, at least in the beginning, when vaccination is dependent on just the Pfizer vaccine. We could look at how Ebola vaccine has been distributed around Africa; it is a specialized cold chain.
