Vaccine procurement figures didn't stand up for long. "10 million" from Pfizer by the end of the year seems to have turned into "800,000 in December and then "...

It's not actually helpful to talk about doses when each person needs two. To be clear, 800,000 doses is enough vaccine for 400,000 people.

Asked government what explains the difference. A spokesperson said: “800,000 vaccines are being brought over now to be ready for the start of next week, and we are in discussions with Pfizer/BioNTech about how many could be provided to the UK by the end of the year.”

So sounds like there will be more this year, but not yet clear how many Pfizer said during the summer it could produce a total of 100 million doses this year but last month revised this to 50 million. On that basis, you'd hope UK would get at least 5 million this year.
