@Nutmeg031992 @juli_bg_bs Right, the question is just what is "a lot". If you have another surge where 40-60% of the population is being infected and reinfected, or perhaps similar in slow motion over months, then even tens of millions of doses is not really enough.
@肉豆蔻031992@juli_bg_是的，问题是什么是“很多”。如果你有另一次激增，其中40-60%的人口正在被感染和再次感染，或者可能在几个月内以慢动作出现类似情况，那么即使是数千万次剂量也不够。
