CV will be around for a long time. I’m not sure what will change in 3 weeks / 3 months or 12 months.
You don't understand what is happening. The lockdown is not happening because of coronavirus. It is not happening because there isn't a vaccine. It is happening only to prevent there being too many serious inflections all at once, to the degree that hospitals cannot manage the numbers.
"Coronavirus" has already been around a long time. Arguably, in some forms, longer than humans have. This particular variety of it is now here, and it is going nowhere. The chances of it being eradicated are, in terms of any science currently on the horizon, nil.
So nobody will be staying in lockdown for 12 months. If the world stayed in lockdown for that long, there would be nothing to come out for!
