It is not possible to predict how this is going with any certainty. But it seems likely that it will be around for a good while,and there is evidence it is already mutating, so a Vaccine will have to be effective against any new strain as well as the existing one to make a dent in this.
Don't think short term, as in " Oh the Curve is on a downward trend, we can return to normal", no you cannot, you must be just as vigilant and sensible when the downward bit starts, as it goes down the slope , yes, but that is just what happens, it does not denote the virus is on the way out, or anywhere near being beaten.
This bastard thing is with us for a while, the only way to beat it, is deprive it of hosts, both animal and human. That is a very tall order in this modern world. I hope you all stay well and safe.
