@_Kodos_ @humftydrumpfty @DrTomFrieden I never claimed that.
"If masks were effective then immunity wouldn't even be a factor"
Again, this is wrong. Paper says 19%. It doesn't say 100% where immunity wouldn't be a factor. Try reading and understanding. It's not that hard.
@_Kodos\uuU@humftydrumpfty@DrTomFrieden我从来没有这样说过。
“如果面具有效，那么免疫力甚至不是一个因素”
同样，这是错误的。报纸上说是19%。它并没有说100%的免疫力不是一个因素。尝试阅读和理解。没那么难。
