I'm just back from mine, not particularly happily as the nurse struggled to get blood out of me this morning and only managed on the 4th attempt!
Anyway was told the same thing as @andadietcoke
Two interesting observations though. Dr Baxter admitted that a lot of people had been unblinded already due to being called up for a vaccine and that he expected many more to do so before starting the crossover - other than me and one other, everyone else there at my time was in their 60s and he advised them to wait and see for now but admitted that if they got a call for a vaccine next week they should ask to be unblinded. He advised me (42) to stay in, obviously I needed no persuasion.
Someone asked a very good question, basically is this trial a proper cross section of society and therefore can we think about the term % efficacy being the same across the whole cross section. Dr Baxter said that basically people in the trial are not really representative of society generally. They are less likely to be in at risk/key worker jobs for starters, mostly due to time. Many are retired (and therefore have the time). And they know that trial participants are more likely to be rule-followers than people generally! I'll take that as a compliment. So he acknowledged that that is an issue generally, but no more so in this trial than others. He admitted that nationally they had failed to get as many BAME people to sign up as they wanted to.
Finally I am quite flabbergasted by the amount of paperwork generated by this. And really surprised things can't be done electronically. This slow everything down considerably. Someone somewhere has to spend goodness knows how much time inputting all the stuff that goes down on paper. And Dr Baxter looks absolutely exhausted, he admitted he is spending most of his time these days actually vaccinating.
In a few days I'll set up this thread part 2.
