Then we're screwed. The entire world must now shelter-in-place like there's a madman sniper on the roof, because this bug is like no other, will never be able to be conquered, has a great chance of re-infecting the carrier (It's called a relapse), and that's it. To save the children who are our future, our existence is now isolated to home with no exposure to the outside world for the rest of our natural lives.
It's for the children.
Anti-vaxxers should be taking note, by the way. This is what they have all dreamt for. This is their gateway to salvation.
