i think Ryan stated upthread that the goal of the initial lockdowns was the "flatten the curve" to protect the collapse of our healthcare system. it worked for the most part. the goal was never to have zero covid cases, but that seems to be Fauci's want right now, which again as stated above, is impossible.
The vaccines don't even 100% protect you from getting covid. However they are 99+% at preventing severe cases of covid, which is really good. But the messaging out there has not reached the general public, aside from us educated folks. It needs to be stated clearly and frequently that even though you have gotten the vaccine, you may still get covid.
Twitter is going to go haywire the first time that someone who has gotten the vaccine gets covid.
