@Tony Babangida or anyone else in very clued up on vaccines, I’m struggling to get my head around how you power these studies. The total number of cases seem absolutely tiny compared to the size of the study.
If you were testing a treatment for heart disease you would only recruit people who had heart disease. So a small difference in the number of outcomes could be enough to give you a statistical significance.
How can anyone say with confidence that if you get, say, 10 cases in the placebo arm vs 80 cases in the active arm that this difference isn’t down to more people being exposed to the virus in the active arm? Obviously you hope the exposure is similar but you can’t be certain and it seems weird to be drawing such strong conclusions based on differences of 80 cases from 80,000 subjects.
