what you're describing is mostly intrinsic to omicron, not vaccines.

Yes. See https://yourlocalepidemiologist.substack.com/p/omicron-updat...

The booster for omicron reduces spread potential?

It's important to note the severity of omicron seems to vary a lot from country to country. Omicron in South Africa seems to be much less severe than in other countries.Also if you do wanna take the hot take of omicron spreading and displacing other variants, then it's still very important to get the booster shot. The vaccine has a much bigger effect on those variants than on omicron. In Norway at a party of 120 fully vaccinated people, 80 of them got infected with omicron. So no ma

I find it weird that there's no mentions of variants, but I assume based on the timeline it's probably Delta and older.Seems impossible to tell if this holds for omicron as well, given that it's replication behavior and general outcome is a bit different and usually more mild.

Citation needed on whether omicron infections don’t confer immunity to the deadlier delta variant. This is likely not true, so what we are seeing is a billion and quarter people speed running through omicron, which all things considered isn’t as deadly as delta. Whatever horrendous stuff happening there, Id say it’s equally possible it’ll prolong for a long time, or can end rather quickly in a month or two.

Waiting for conspiracy theorists to claim that the Omicron variant was the first test of this technology since it was fairly mild and spread so quickly giving most people who caught it some immunity against other COVID strains that are deadlier.

Source please? Everything I've read about latest Omicrons suggests that they are more transmissible, more likely to evade immunity, and substantially _less_ severe in terms of hospitalization and deaths. By and large, this is what you'd expect to happen at the end of a pandemic, regardless of our response.
