The feeling I am getting is that AZ is being less cautious with their promises. What I fear is that they did the same with their fase 3 trials. I read an unsourced claim on HN a few weeks ago that they did 9 phase-3 trials, and applied for approval on the basis of only 2. Which would be rather bad if true. Moreover, it is clear that their 1.5 dose regimen was a mistake in trial execution. Meanwhile, the FDA still hasn't approved AZ. It seems possible that AZ was overeager to present good results, and thus was less cautious than they should have been. It's only a possibility, but its one that worries me. Anyone here have an source to confirm / debunk the rumor that AZ did 9 trials, and only applied on the basis of 2 trials? edit: I just looked at the stats in the UK, and it certainly seems like since they started vaccinating cases have dropped off, and deaths have dropped of even faster. Since vaccines are probably targeted at the more vulnerable, it certainly seems to show that the vaccine has very positive net effects.
