@RidleyDM @BallouxFrancois Sort of. Severe disease is a narrow slice of symptomatic disease. You can have a large reduction in severe disease w/o much reduction in symptomatic (as now) but you can also have a large reduction in symptomatic without ANY reduction in severe.
@RidleyDM@BallouxFrancois有点像。重症是症状性疾病的一小部分。严重疾病的发病率可以大幅度降低，而症状的发病率却没有大幅度降低（就像现在一样），但症状的发病率也可以大幅度降低，而严重疾病的发病率却没有任何降低。
