The best way is a vaccine. And with all the smart folks out there working on one, I think it's just a matter of time before one is released to usins. I don't think "letting it run its course" is the best answer. Just in the last day we've had the UK study that suggests immunity does not last that long. https://www.reuters.com/article/uk-health-coronavirus-britain-antibody-idUSKBN27C005 So without a vaccine we would have too: Let it run its course. And then let it run its course again. And then let it run its course again. And then let it run its course again. I think you get the point. And with each "Let it run its course" another bunch of people die. That may be a plan, but it's not a good plan IMO.
