Pfizer submits data showing Covid vaccine's stability in refrigerators

If approved, this new storage option would offer pharmacies and vaccination centers greater flexibility in how they manage their vaccine supply

Pfizer Inc. and BioNTech SE asked the US Food and Drug Administration to allow their Covid-19 vaccine to be stored for two weeks at temperatures found in normal pharmaceutical freezers, a change that could simplify distribution for the shot.

The partners submitted new data showing stability when the vaccine is stored at minus 25-to-minus 15 degrees Celsius (-13°F to 5°F), they said in a statement on Friday. Current protocol is for storage for up to six months in an ultra-cold freezer at temperatures of -80ºC to -60ºC and shipping in a special thermal container.
