The fridges used, say in a surgery, are not like your domestic one, they are specialist scientific ones with calibrated temperature control, usually quite small.
Clearly this second vaccine would be more convenient in practice than the Pfizer one.

Weren't you the same guy a week or so ago who was severely criticizing Mark Drakeford for not immediately investing in loads of infrastructure to deliver the vaccines at -70C , then there were people involved in the cold delivery logistics type company saying that that would be a huge challenge as the capacity would be massively exceeded.
Something that would last for 6 months in a normal freezer and 1 month in a normal fridge would clearly be much easier to manage a large scale roll out.
