I would love for what you say here to be what happens.
Sadly I really doubt it.
The way I see it, we managed to create these amazing vaccines. Not only could they defeat original Covid with only two doses. They could also combat closely related variants like Alpha, Beta, Gamma and Delta.
Then along came Omicron. That was a heavily mutated variant that apparently contained aspects of Delta mixed with aspects of the Common Cold. And yet, despite being so different from what came before, all it took was a third shot of the un-edited original vaccine and we were all good.
There can't be too many more places for Covid left to hide or transform into now. Three jabs can beat not only the original but ALSO all of its brothers AND its cousin. Subsequent vaccine tweaks are going offer even more generalised protection on top of that.
With this level vaccine effectiveness, plus the transmissibility of Omicron adding an extra layer of immunity to the unvaccinated, I reckon we're in the final stretch. Just need to get those boosters into arms.
Obviously, we're still in the middle of massive wave in which lots of people are going to sadly get sick and maybe even die. A circuit breaker is probably still going to be necessary to flatten the curve for the sake of the NHS. So nobody with any power should be sounding the trumpets or raising the bunting. But I'm just some chode on the internet so I can get away with wild conjecture.
