What I'm trying to understand.
Why are they even talking about a second wave in the winter? With flu you can see it coming already now and they get working on a vaccine, based on the flu in the southern hemisphere winter.
Why specifically winter, if they fear an eventual new strain? It's not like anywhere in the world has seen a confirmed new strain until now.
Also, if they are afraid about immunity wearing off before the fall arrives again, why aren't we seeing confirmed reinfections in SE Asia, where this has been around now for a half year? If it wears off after any period, we should have warning.
