It's not that they've just discovered that - it's that it's now an approved storage option. We know the vaccine is stable at normal refrigeration temperatures for up to 5 days - when the vaccine has been taken from the super cold storage it is then stored for up to 5 days before use.
This new storage option means it can now be distributed from the super cold freezers and and stored in regular vaccine freezers for up to 2 weeks before being stored in a refrigerator which will do a lot to improve supply chains.
