We have Zero immunity, we are all going to get it, end of story, not an opinion 100% fact.
Only China that did shutdown ( did they ? ) is on the maybe the other side, even then they might not be over yet, but so far hasn't came back, which means most people there have had it and are currently immune. Nobody else is on the other side and nobody who hasn't done shut downs and economic suicide.
We'll have to see how this shapes up, too aggressive and it'll be back and more lockdowns, I suspect UK's 80%+ infected.
If you think that, you will see that it is easily 100k deaths or more. I don't understand what everyone is arguing about. Everything in this world is uncertain. Starbucks earnings is uncertain....markets are. But still we make predictions anyway.
