Glad the elimination strategy is finally being discussed. It should have been the goal from the start. Get rid of it and don't let it back in.
There seems to be a fair amount of evidence that antibodies which confer immunity do not last long for this virus. What seems to be happening is that the body creates quite effective antibodies to fight the virus (in most cases) and a few months later they're gone.
This means a vaccine could be very difficult.
Which leaves pretty much one solution, get it out of the human population. The only way to do that would be to eliminate it amongst different populations with very strict quarantine and you need to get rid of it everywhere. It is a very tall order but maybe we have no choice.
Or, we could be lucky and it mutates to something less virulent or less harmful.
I reckon we need to pursue elimination, at the same time as continuing the research for a vaccine. If we don't eliminate, we will end up in lockdown again and again.
