if the vaccine is ~90% effective, wouldn't we expect that for any ten random cases in the trial, 9 would be in the placebo group?
i don't see how that rate implies anything about the severity of the infection
- ummonk 6y agoIgnoring statistical significance for the purposes of this discussion, the observed rate suggests that the vaccine is 90% effective at preventing severe infections as well, not just mild infections. In a worse world it could have been the case that e.g. the vaccine was 90% effective at preventing infections but still had the same number of severe infections because it did nothing to help the most vulnerable patients.
