Each of the four countries in the U.K. have devolved responsibility for the administration of the vaccine once it’s delivered, which is why the prioritisation and administration arrangements will be different in each country, the amount of vaccine is allocated based on the size of the population.
On tonight’s Welsh BBC news it was said that the target is for all eligible groups to be done by Easter. I think they will use mass vaccination centres or hospitals for the Pfizer vaccine because of the storage and reconstitution requirements, and local centres for other vaccines as they become available. This may not be GP practices everywhere, as they also have the task of administering many more normal flu vaccines this winter because the eligibility has reduced to age 50 and they have limited staffing.
The point was made on the news that this is a huge logistical exercise, with a level of urgency that means that we can’t expect it to run completely smoothly throughout the whole U.K., but we will all be offered the vaccine in the next few months in a venue that may be difficult, but won’t be impossible for us to get to - some travel compromises may have to be made, particularly by younger and more mobile people, and some older people who can’t travel may have to wait a bit longer - but if we can all get it by Easter I think most people will be prepared to wait a little while.
