Coronavirus 2019-2020 thread (no unsubstantiated rumours!)

How does one develop herd immunity to a virus that is constantly mutating? Given that a flu vaccine provides protection for 6 months, what can we realistically expect from a covid vaccine?

This piece came out a month ago. It may suggest that it's going smoothly... As of last December, 5 individual subjects had entered a phase 3 trial. It seems that they are confident enough to start a factory for mass production.

Actually the 5 different subjects are referring to the following: Sinopharm I, Sinopharm II, Sinovac, Cansino Biologics, Anhui Longcom/CAS. None of these are mRNA.

It hasn't evolved enough to overcome herd immunity yet I guess.

That's why you'll get waves of mass deaths and debilitating "long covid" signs and symptoms in survivors; it's far more comparable to a smallpox plague than Spanish Flu in that case.

The UK Strain is confirmed to be more infectious and more deadlier than vanilla COVID.

Let us remind historians here that this could have been avoided if the Anglos had foregone racial cold war in favour of a more united world response against this century's 1919 H1N1 pandemic.

Yes, you are correct. I misread.
This is strange. We recently had a woman who returned from Europe in a little over 3weeks ago. During a period of 14 days of isolation, she returned a negative test for covid twice. During the next few days, she spent days and hours visiting heaps of shops and cafes and bars and supposedly intimate with her husband as well as associating very closely for hours on end with her friends. On the day3 of her release, she began to feel unwell and a couple of days later she tested positive for the South African covid strain, and yet none of her friends or any members of the public that were in the same bars/cafes she visited have returned a positive test.

Same thing happened to the outbreak in Shenyang a month ago. After 14 days of isolation in hospital with multiple negative tests, the old lady went home for 7 more days of self isolation but she didn't and infected hundreds of people afterward. For whatever reason, the virus incubation for some people is just much longer than others.
