These calculations aren’t stratified by age / prior risk, so you can’t really infer the efficacy this simply.

- orbifold 5y agoThe original statements of vaccine efficacy were also not stratified in that way, were they? With delta you arrive at ~39% relative risk reduction of preventing a positive PCR (instead of >95%) and ~59% relative risk reduction of preventing hospitalisation. That would also be true if you randomly drew people from the population and conducted a study, no? Of course it still can mean that your individual benefit is much higher.
