Maybe this has been answered, but the virus will always be out there somewhere and we can't stay in personal and economic lock down forever.

As soon as we get back to some kind of normality, won't we be back to square one?

Even if it was eradicated in one country, as soon as the border opens, it will be back in from somewhere.

Only solution long term is a mass vaccination programme, but with little hope for one this year I believe.
