Skeptical of your sources. South African doctor who was one of the discoverers of the variant said it characterized by mild illness with a unique symptom profile. I'm assuming SA would have both a large number of unvaccinated as well as a large number of recovered/natural immunity yet no such indices as you claim were mentionedEarly info says the vaccine is still effective against omicron. The unvaccinated are twice as likely to develop serious illness, and those with prior immunity appear to be susceptible to it. YMMV.
In other countries, such as the EU, the number of cases is minuscule - too small to try to infer anything about trends vis a vis progression of illness (I think the UK had something like 39)
Concerning what I color highlighted in the quote, with a goal of vaccinating everybody above the age of 5 an untold number of times I would expect them to say nothing else - just like when the Israeli study indicated natural immunity was far better than vaccinated immunity there was a rush to put out information to the contrary
