You cannot grasp this amount of stupid! We have 330 million Americans, some of which are children who I believe will not be getting the vaccine so I think 300million doses would be enough to cover everybody. A “dose” is 2 shots given 1-2 wks apart. So is Sleepy talking about “doses” or “shots”? Two different things. But at the end he says “....600 million doses should cover ‘300’ Americans”.‼️ ? ???????????????????????
