@RidleyDM @BrennanUncle @RadioFreeTom @mehdirhasan Can't tell you what is acceptable or practical but pretending vaccines are effective in mitigating high transmission environments other than as one layer of multiple is just failing to face reality. Seemed at one point like it could have worked, but facts evolved.
@RidleyDM@Brennanuble@RadioFreeTom@mehdirhasan无法告诉你什么是可接受的或实用的，但假装疫苗在缓解高传播环境方面是有效的，而不是因为一层多重疫苗无法面对现实。在某一点上，这似乎是可行的，但事实发生了变化。
