Just acouple of things I heard onb the radio today whilst driving around.

This virus has to be kept at low temperatures of about -80 for storage but is stable for up to 48 hours after being taken out of that and mixed with another liquid for vaccination and then stored in a fridge. Such as in a pharmacy or doctors surgery.
A GP leader said when interviewed that the plans to deliver vaccine had been on going 'for some time' and they didn't envisage any serious problems when the time came.
The rapid tests being done in Liverpool are apparently to try to find those who are asymmetric, but someone from NHS said anyone testing positive from a quick test will then be sent to a test centre for another confirmatory test like people are having now.

As a comment on where PHW is ready or not, I was at the NHS Distribution centre near Newport yesterday sand the Virus lab personnel were out loading large polystyrene boxes about 600x600x600 in which were deep cold containers for vaccine. It belies the comment that nothing was being done.
