There's an issue with this approach that I think is being overlooked.
Let's say we go ahead with the vaccine release asap, and that you get a good number of the public receiving it without panicking about Bill Gates and microchips. You're going to get a massive push at the same time to open things up in full, since hey, we've got a vaccine now right? And you're not going to be able to deny people from opening up, because the line almost from the start has been that a vaccine is what's needed to return to normalcy.
Most people aren't going to bother with any nuance from here, it's just going to be, "I got the shot, I can live my life again like from before".
Now what happens if that vaccine is only 10% effective. Everyone walking around like they've got a bulletproof vest on that isn't doing shit.
Will releasing the vaccine early save more lives than it will take? I think the answer is that it's an enormous gamble that has a terrible risk.
