@WSpunkmeyer @greggwbarnes @benny171a @TrumpUndead @jonathanchait That's how vaccines work, especially the inactivated polio vaccine which is known not to stop infection. There are people being infected with polio in NY right now. Healthcare workers with a high risk of exposure are getting boosters.
@WSpunkmeyer @greggwbarnes @benny171a @TrumpUndead @jonathanchait 这就是疫苗的工作原理，尤其是已知不能阻止感染的灭活脊髓灰质炎疫苗。纽约现在有人感染小儿麻痹症。暴露风险高的医护人员正在接受助推器。
