@tiggerbluedevil @mskathleenquinn @andyaschmidt ^ That was in March. Vaccines started in December. By March it still wasn't known if vaccines would stop transmission.
So I don't know who told you to tell patients we did know that, but they were wrong.
@那是在三月份。疫苗于12月开始接种。到3月份，还不知道疫苗是否能阻止传播。
所以我不知道是谁让你告诉病人我们知道，但他们错了。
