$OCGN the 60 % efficacy result was for phase 2, pfizer had 52 % efficacy for phase 2 i wont go into statistical math because its complex and boring and im just a truck driver :P but basically the bigger your test group, the higher the efficacy since you are betting AGAINST chance encounter and FOR normality its the same as what are your chance of winning SOMETHING with a scratcher ticket, lets say 1/10, what are your chance of winning 2 things in a row, 1/100 3 ? 1/1000 its much more complex than that, but the bigger the sample size the less arnomality the less anormality the more you toward the same trend you are already moving along, in that case a negative result from a covid test,
