Pfizer COVID-19 vaccine can now be stored in a fridge for longer, Health Canada says

The Pfizer-BioNTech COVID-19 vaccine can now be stored at normal refrigerator temperatures for up to 31 days, Health Canada said in a press release Wednesday.

The vaccine was first authorized with a recommended storage temperature of between -80 C and -60 C. Once thawed, vaccine vials could only be stored in a refrigerator for up to five days. This change significantly extends the length of time the vaccine can be stored in a normal refrigerator, meaning that facilities lacking deep freezers are able to keep the vaccine for longer.

“This change means that there will be more storage options available for the Pfizer-BioNTech vaccine, which will allow for more flexibility in distribution plans,” reads the release.
