@NeilWC2010 @yannotyam @gregggonsalves @AshishKJha46 @WHCOVIDResponse The would clearly be true if the effectiveness were 100% with respect to both acute and long-term disease. Neither is true.
If not, then it's a judgement call, and looking for layered measures is entirely reasonable.
@NeilWC2010@yannotyam@gregggonsalves@AshishKJha46@WHCOVIDResponse如果急性和长期疾病的有效性都是100%，那么这显然是真的。两者都不是真的。
如果没有，那么这是一种判断，寻找分层措施是完全合理的。
