@Kathryn78917961 @APazyryk @BallouxFrancois @sdbaral Even before November, efficacy may not have been "clear" but there was good reason to believe it, again suppression if acceptable cost is a good gamble. Worst case is purely delayed impact, which is still a benefit.
@Kathryn78917961@APazyryk@BallouxFrancois@sdbaral即使在11月之前，疗效可能还不“明确”，但有充分的理由相信这一点，如果可接受的成本是一个很好的赌博的话。最糟糕的情况是纯粹的延迟影响，这仍然是一个好处。
