The point is that 1) after omicron recedes, there won’t be much infection going around for a while, local spread should go near zero; and 2) if you get infected from your own previous illness, it is guaranteed your body has defeated that specific pathogen (variants, mutations) and should – given you still have immunity as you have recovered – be able to defeat it again, better than random other person’s variant. Your own previous illness should be safer for you than random other person’s random illness.
So if I don’t get ill but remain immunonaive aside vaccine, surely then I will just enjoy my infection-free life until the next wave. But if I get infected, and there is not likely new vaccine doses available, I have interest on keeping my immunity against infection high with repeated infections the body has learned to repel. That way the next wave in around 2022-08 should have much lower probability to give me an actual infection.
