@juli_bg_bs Not so fast. Going back to March 2021 means not only is this largely pre-Omicron data but some of it is even pre-Delta. Effectiveness against a virus that doesn't exist any more doesn't seem particularly relevant today.
@juli_bg_没有那么快。回到2021年3月意味着这不仅仅是前OmiCon数据，而且有些甚至是前三角洲。对抗一种已经不存在的病毒的有效性在今天似乎并不特别重要。
