We will never be rid of COVID-19. The expectation is that it will join the annual rotation of respiratory viruses and that we will be able to get an immunization against the most prevalent strain every year. As people are immunized or exposed to this category of virus our immune systems learn to recognize that the new strain is 'sort of' like the old strain, so it should respond better than it does to something totally foreign for which it has no defenses. Actually, it is probably not the 'better' it's the 'quicker'; the sooner your body recognizes the invader the better it is able to fight it off.
On the subject of 'normal' we'll probably wear masks for a long time to come (those of us living through it now). This has been a bit of wake-up for humanity. And based on our human nature, many of us will take precautions for the foreseeable future and slowly taper off. But future generations will not remember and will become fully complacent about the risks and in about another (2020-1916) 104 years some horrible virus will descend upon mankind. History often repeats itself.
ETA: get the vaccine. Even if it isn't perfect against a variant, your body will be better able to recognize and respond to it. A boxer without gloves can still win a fight, but if you don't know how to box, you're in trouble.
