These stats are based on 130 people getting covid out of an experiment of 25,000 people. They dont give a breakdown of the stats (e.g. who was on placebo, who was on which dosing regimen ) but those are small nubmers. I think its possible that this is just noise. The difference between '60%' and '90%' might just be a handful of cases. They show that it works though, thats the main thing. edit: e.g. of those 130 cases lets assume half were in each regimen experiment. So 65 cases in the 'two full doses experiment' if they got 60% efficiacy then that means about 26 people with the vaccine got covid vs 39 with placebo. In the 'half dose then full dose' experiment if they got 90% efficacy then that means about 7 people with the vaccine got covid vs 58 with placebo. So the difference between 60% and 90% is 19 people. They show that the vaccine works but there is lots of uncertainty between the two dosing regimens. Edit: why the downvotes?
