So, out of 43538 participants, 94 got sick in both groups (who got vaccine and who got placebo) together, and this translates to "at least" 90% immunity, with 95% confidence interval.
Who remembers statistics well enough to reverse the calculation and find out how many people got sick in both groups? There is a definite integer answer here.
- tomerico 6y agoAssuming 50% split between placebo and vaccine group, it's a 9:1 ratio - so 85 : 9 for Placebo : Vaccine COVID case.
- anovikov 6y agoThat would be middle point - that is 50% chances that actual reliability is better than 90% reliable, 50% that it's worse. But we have 95% confidence interval. This is what my question was about. On infinitely large number of cases, the numbers will be the same. But we only have 94. I think it's about 2 to 3 cases that they actually got from the group that got vaccine, but not sure.
