FWIW. I think Omicron is going to change things. In a few months virtually everyone will either be vaccinated, have gotten COVID at least once, or both. The reality is triple jabbed plus Omicron seems to confer tremendous immunity. Quadruple jabbed likely will as well, and even if a quadruple jabbed person manages to get it, it will be mild.
I think between the Pfizer pill, the effects of Omicron, it’s lesser virulence, all the boosters, etc, by June there is a very good chance “returning to normal” would not be any less safe for the triple (or quadruple) jabbed than acting normally during a typical bad flu season. I now know several people who’ve had Omicron. All were triple jabbed (including one who got his third jab in August). None of them experienced anything as severe as a typical flu. It’s anecdotal, but that seems to be consistent.
Something worse than Omicron may come, but by then there should be a lot of built up immunity and drugs to combat it.
