@WSpunkmeyer @greggwbarnes @benny171a @TrumpUndead @jonathanchait It's not work or not work. For one thing, covid vax very effective at preventing severe disease and death. That counts as "work". For another, it's a matter of degree. Flu vax don't prevent much infection either, and millions get flu anyway, but still accepted to work.
@WSpunkmeyer @greggwbarnes @benny171a @TrumpUndead @jonathanchait 这不管用还是不行。一方面，covid vax 在预防严重疾病和死亡方面非常有效。这算作“工作”。另一方面，这是一个程度的问题。流感疫苗也不能预防太多感染，无论如何都有数百万人感染流感，但仍然接受工作。
