@usual_suspect89 @JeromeAdamsMD @scheib_gary Waning immunity may or may not (seems debated) but mutations/variants that evade immunity certainly have. Vaccines (esp 2 doses) are much less effective against serious disease w/Omicron than previous variants.
@通常的怀疑89@JeromeAdamsMD@scheib_gary免疫力减弱可能会也可能不会（似乎有争议），但逃避免疫力的突变/变体肯定会有。与之前的变种相比，疫苗（esp 2剂）对含奥米克隆的严重疾病的效果要差得多。
