As I suspected and stated last Friday. This 'moving around' story is BS. IMO, it's designed to preserve a very small order of this vaccine for the NHS, and they're having to spin this story because the Oxford vaccine isn't anywhere near as efficacious as Pfizer or Moderna (and probably not even Sputnik), but that's the only one that will be administered to the vast majority in this country.
Again, this government has made a complete balls up of the vaccine to go along with their failure to lockdown early enough, failure to ensure enough PPE was there for the first wave, failure on trace and track testing, and failure on its tier system.
Mark my words, many people who can afford to shop around will do so and get hold of Pfizer's vaccine...by hook or by crook.
