@boodad12 @TrumpUndead @jonathanchait That's false. The CDC HCW study in early 2021 tested for infection and transmission.
It was one AFTER that study that CDC, etc. started saying that vaccines stopped infection. Previously they told people to keep their mask on after vax because they didn't know.
@boodad12 @TrumpUndead @jonathanchait 那是错误的。 CDC HCW 研究于 2021 年初进行了感染和传播测试。
在那项研究之后，CDC等开始说疫苗可以阻止感染。以前他们告诉人们在vax之后要戴上口罩，因为他们不知道。
