Vaccinate the population as much as possible, then pursue super immunity for what's to come via exposure to this luckily less severe and highly contagious variant while the vaccines are still potent.
I don't know how people square "let everyone get it" with points about how immunity after getting it only seems to stick around for 2 months, or even less with variants!
Unless you're saying we should purposefully infect everyone at the same time. I don't have a better answer, but I don't like pretending that this will magically improve just cuz everyone gets sick once.
This is the way.
