The trial saw about 220 participants infected -- 160 in the placebo group while almost 60 received the vaccine, Covas said. (160-60) / 160 = 62.5% 78% 怎么算出来的? 难道真是中和了土耳其92%? (62.5+92)/2 = 77.25 Moderna: (185-11)/185 = 94.05% Today’s primary analysis was based on 196 cases, of which 185 cases of COVID-19 were observed in the placebo group versus 11 cases observed in the mRNA-1273 group, resulting in a point estimate of vaccine efficacy of 94.1%.
乱说,推迟是科兴要求,现在这个78%也是一个数字,多少实验人口数据detail没有,怎么算出来的78%也没有,不透明,还不可信
巴西的数据是只有63%,不过科兴自己说是78%
