The point is that jabbed versus unjabbed takes precedence over the 3 above listed categories. If everyone who can be jabbed is; then the above 3 categories need not apply, even in the case of omicron. This is especially the case if a booster is given, creating secondary immune response to Sars-CoV-2.
Yes, there will be some immune escape but many of the antibodies that are acquired via boosters will cross react with omicron.
