> Moderna's vaccine appears to be easier to store as it remains stable at minus 20C for up to six months and can be kept in a standard fridge for up to a month.
Pfizer's vaccine needs ultra-cold storage at around minus 75C, but it can be kept in the fridge for five days.

It was common knowledge that Moderna’s vaccine was releasing efficiency results this week, and that the technology used to provide protection was very similar to Pfizer’s.
