I think covid will continue to pose a risk in the long term with waves of infection of differing severity. I don't think we will return to a totally pre covid world where we interact totally as before. I think we will return to a world much more like the one we used to inhabit what it's like we will have to wait and see.Viruses and bacteria live with us and always have done. Completely eradicating an organism that makes us sick is a noble aim but is not one that is easy to achieve. Are you suggesting that we will always be "in the woods" until Covid-19 is eradicated?
Smallpox was completely eradicated, worldwide in 1980. However, it took more than 200 years and a worldwide vaccination program to eradicate this disease.
It could be our world has returned to the old old normal as I'm pretty sure in waves of smallpox infection people would not have continued their lives totally unchanged but modified their actions to try and limit risk albiet with little knowledge of what the infection was.
