@mrbcpa99 @MelpomeneMel @AshishKJha46 There is significant cross immunity between BA1 and BA5 but the vaccine may improve it.
Also, BA5 is on the way out, or a least decline. What nasty is causing problems in a few months we don't know yet (it could be a resurgent BA5, but may not be).
@mrbcpa99 @MelpomeneMel @AshishKJha46 BA1 和 BA5 之间存在显着的交叉免疫，但疫苗可能会改善它。
此外，BA5 正在退出，或者至少下降。在几个月内我们还不知道是什么令人讨厌的问题（它可能是复兴的 BA5，但可能不是）。
