@VGrubsky @alexmeshkin Zero vaccines was sufficient for many people to overcome Omicron or for that matter earlier variants with mild symptoms, or even in some cases, no symptoms. Risk factors (mostly age) plus luck of the draw to a large extent (obviously vaccine shifts the odds in your favor).
@VGrubsky@alexmeshkin零疫苗足以让许多人克服Omicron，或者就这一点而言，早期的变种有轻微症状，甚至在某些情况下没有症状。风险因素（主要是年龄）在很大程度上加上抽签的运气（很明显，疫苗改变了对你有利的几率）。
