Not with the same rates. This should be kept into account, because when lockdowns will be lifted (you will have to at some point, even if it's just to prevent people from becoming insane), you won't have a risk of 0, so letting the lowest-risk population out first is a goood bet.

But there are drugs in development and in trial. None will work miracles, some will not work at all, some will have marginal impact, some will have a little more impact. Those are the best bets at this point in time.

Waiting out for a vaccine, like many governments are hoping for, is irrational IMO, because there's no guarantee that a working one will be found - and you can't lock up your population for 18 months, even if you don't factor the economy in, because people will be destroyed psychologically.
