Both my parents, sister, and a slew of friends and co-workers have had "breakthrough infections" from covid, I'm not really sure (if you're not getting boosters) whether you even have protection from regular let alone Omicron at this point.
That only means you're in the place with a lot virus flowing around, nothing else. Vaccine stimulate your immune system to lower the chance to get infected, and even if infected much lower chance to get severely damaged.
I’m not sure your explanation is sound. Studies have shown doctors/nurses get sick (pre-Covid) at more or less the same rate as the rest of the population, despite increased exposure to circulating colds and flus. Explanations ranged from “they get vaccinated more” to “background exposure to very low payloads primes the immune system and keeps them healthier.”
I hate to put it in these terms, but do you have credible peer reviewed literature on this claim? What you're saying is exactly what state media & state authorities started espousing after everyone realized the vaccine didn't offer the protection everyone had assumed and been promised. I'm wondering if there is any actual evidence for their claims or if it's just saving face and moving goal posts.
