@dave_m_ @MDaware @beyerstein I'm telling you it doesn't make much difference if the people masking are vaxed or unvaxed.
CDC tried that in May '21. After eventually facing reality, they dropped vax status as being relevant in areas of moderate or high transmission. The same is even more true today.
@dave_m_u@MDaware@beyerstein我告诉你，如果人们的伪装是VAX或UNVAX，这没有多大区别。
疾控中心在5月21日尝试过。在最终面对现实后，他们放弃了vax在中度或高度传播地区的相关地位。今天的情况更是如此。
