  1. ​ @daverok1113  Efficacy could mean various things but RRR seems the most obvious. If I am exposed, how much protection does it give? Answer: 94% to 67%. "Ranking by reported efficacy gives relative risk reductions of 95% for the Pfizer–BioNTech, 94% for the Moderna–NIH, 91% for the Gamaleya, 67% for the J&J, and 67% for the AstraZeneca–Oxford vaccines." (your citation) However if you are asking "How does this vaccine help the nation" then sure, ARR might be the right number to use. But ARR doesn't seem to be "efficacy" because it includes both the vaccine protection and how common the virus is at the moment. Am I getting this right?
