@mikejohansenmd @MarkELindsay Yeah, well I have three doses. Many don't. Until there is some way to successful sell that (and then resell it when it wanes), it's not really working at the population level. But I certainly recommend it!
@mikejohansenmd@MarkELindsay是的，我有三剂。很多人不会。除非有办法成功销售（然后在价格下降时转售），否则它在人口水平上并没有真正起作用。但我当然推荐它！
