> The incubation period was plenty long enough for the virus to spread before incapacitating the host. All the selection pressure was for the virus to become more virulent - and that is precisely what happened. We saw multiple strains appear which were harder to deal with.

Is Omicron equally as deadly as Delta? No.

> This had a negligible impact. Patients were only put on ventilation when they were already very sick and at a high chance of death. Worldwide only a tiny proportion of deaths came about in this way. Even rich countries only had ventilators in the tens of thousands. Compare that to the billions who received vaccinations.

That's just one example. Not using effective antivirals is another one. With time, treatments improved and so did the outcomes, regardless of vaccination status.
