Okay. Thanks.
So naturally they don't know because it's a new virus. Fair point.
But of course this is true of every new virus every year. Don't we usually assume once we have a particular bacterial or viral ailment, we don't get it again? Why is it different for this one?
After all, it's not the virus that has the memory. It's the immune system. And as I understand our experience of the immune system, it is that it has a pretty good memory.
Not sure why the base assumption isn't of immune memory, rather than cellular amnesia. I'd be looking for solid evidence of amnesia before proposing it.
Viruses evolve, so we may see a new version of this one day. But that's not the same thing as getting Covid-19 twice.
Maybe I am wrong about this. Not a doctor. But I think the assumption of herd immunity is a far better bet when dealing with unknowns.
