WM, that is a "Realistic" expectation based on Flu like vaccination schedules. It is not based on an emergency crash program to immunise hundreds of thousands, or millions, of people per day.
Yes there are logistics, the vaccines have to get to the centres, people have to be contacted and requested to attend, staff have to be available to present the vaccine and then it will, also, take 56 days and two doses before anyone vaccinated is guaranteed to have developed the right levels of resistance.
There are ~8,000 doctors surgeries in the UK. At 250 people per day that is 2 million people per day. 2 or 3 shifts should do it. There are 1,257 hospitals in the UK. 3 shifts should be able to clear an average of 2,500 people per day; there is enough space and with correct staffing over 24 hours at three shifts should be perfectly possible. That is another 2.5 million people per day.
1 week to first vaccination.
28 days to organise the documentation, shift the new serum and do it again.
Barcoding and simple database recording simplifies the process and gives immediate notification of who has had the vaccine or not. It is not a difficult process to send each person an individual barcode which can be scanned during immunisation.
This is what is called emergency mobilisation. It is possible, it has been done before. It is only people who think that only normal processes will be used that think it will take up to a year to vaccinate the 30m people. It is frustrating in the extreme. Experts, thinking inside the box. Lovely!
If you look up the fights between the unions and the company owners in the courts, you find that the "experts" had allocated how many calories a Stevedore required for a full days' work. The Unions produced the plate of food that those calories represented. The unions won.
I'm all for experts who are pragmatic, understand the challenge, rise to the challenge and think outside the box. I have no time for "experts" who say "well if we just send people to surgeries, then it will take all year".
Especially when not vaccinating is killing the economy and, quite literally, thousands of people.
