This, by @ChikinaLab & @WesPegden is smart.

I've been saying for some time now, that — absent a vaccine — there will be a second wave when we relax social distancing. https://medium.com/@wpegden/a-call-to-honesty-in-pandemic-modeling-5c156686a64b

If you want to argue for a summer lull, through seasonal forcing, then that's fine with me. Time will tell.

In this case, the second wave comes in the autumn. It still comes.

The only thing, apart from a vaccine, that will stop the second wave, is herd immunity, which I discussed here: https://twitter.com/AndrewNoymer/status/1244336159540383745

Also: Widespread masking will probably help spread things out and may result in more infections, when they occur, being milder.
