Nuke, you said Another point to note is that the group members from now should be more 'mobile' than the groups already given the first jab and so, as long as the vaccine is available, vaccination rates may/should increase

That's why I think they may start the 24/7 vaccination centres. They said they would after the top 4 groups were done. But of course they need the vaccines to do that.

Spencer the only thing I can "guess" it could be is perhaps they are not being sent as many vaccines at the moment so are running half day clinics? Even if that's true you would of thought they would do some mornings some afternoons.
