@tiggerbluedevil @mskathleenquinn @andyaschmidt No you weren't. You were told to keep your mask on because it wasn't whether vaccines would stop transmission. Later on the opposite was claimed. Perhaps it was true at the time (to an extent), but the virus and vaccine efficacy is not static, both changed.
Cope.
@tiggerbluedevil@mskathleenquinn@和Yaschmidt不，你没有。你被告知要戴上口罩，因为这不是疫苗能否阻止传播。后来有人提出相反的要求。也许当时（在某种程度上）确实如此，但病毒和疫苗的效力并不是一成不变的，两者都发生了变化。
