The EMA has extended the recommended approved storage period for an unopened thawed vial of the Pfizer-BioNTech vaccine from five days to one month.

Previous advice stated that the vaccine needed to be kept at an ultra-low temperature, between minus 70℃ and minus 80℃, until a few days before use when it can be transferred to a standard medical fridge.

This news comes just days after research suggested a 12-week gap between Pfizer doses significantly increases the immune response in older people by about 3.5 times.

The EMA said: “Increased flexibility in the storage and handling of the vaccine is expected to have a significant impact on planning and logistics of vaccine roll-out in EU Member States.

“The change was approved following assessment of additional stability study data submitted to EMA by the marketing authorisation holder.”

This increased longevity to the vaccine’s fridge storage will transform the way it can be stored and rolled out.

BioNTech said on 10 May that there was no evidence its jab needs updating to protect against variants.

A UK study also found that 96% of people develop COVID-19 antibodies after one jab.
