that Omicron is going to make perfectly clear - is that there is no 'normal' per se out there. With vaccination rates flattening out (and perhaps going backwards in regard to boosters) - there really isn't an achievable level or milestone of protection that can be reached. And so - talk about 'pushing the button' or 'waiting a little bit longer' - have really ceased to have any relevance. We're going to have to learn to deal with a certain level of infection, for a long, long time - if not forever.

second point:

Has always been the case. Even back with the original variant(s) and fullest protection - there has been some possibility of breakthrough infection. What has stayed the same is that vaccinated breakthroughs are consistently less serious, and for the most part non-life threatening. That remains true with Omicrom - with the difference being that 'breakthroughs' become much more prevalent with all vaccine types - and with the non-mRNA vaxs, almost routine or inevitable.
