If im in the 10% it isnt effective on.... will it still likely reduce the severity? Or does it not work at all on 1 in 10...
90% efficacy doesn’t mean that - it’s the amount of reduction in cases of disease compared with the control group. For example, if 100 people in the control (placebo) group in the trial got symptomatic covid, only 10 in the study (vaccine) group did. However, there was 100% reduction in hospitalisation, meaning that of those 10 subjects who developed symptomatic covid in the study group, none of them had severe disease or needed hospitalisation
