The BioNTech/Pfizer have said they’ve submitted new data to the US Food and Drug Administration showing their vaccine can be stored at “refrigerator temperatures” rather than the ultra-cold levels currently mandated.

Stability data, which the companies have submitted to the US regulator, show the shot can be kept at normal medical freezer temperatures of minus 15C to minus 25C for up to two weeks, compared with the previous required storage conditions of between minus 60C and minus 80C. 

Under current guidance, the Pfizer-BioNTech vaccine must be stored at ultra-cold temperatures, and the extreme requirement has impacted the jab’s usage in many countries around the world, as the necessary cold-chain capability is not universally available.

The new storage requirements should ease those constraints and make the vaccine more competitive. Moderna’s Covid-19 vaccine, based on similar messenger RNA technology, can already be kept at normal refrigerator temperatures of between 2C and 8C for 30 days.

In November, Pfizer’s vaccine became the first Covid-19 vaccine candidate to release its complete phase three trial data. It is now widely used around the world.
