Omicron May Infect Half of Europeans Within Weeks, WHO Says:
More than half of Europe's population could become infected with omicron within weeks at current transmission speeds, a World Health Organization official said.
The fast-spreading variant represents a "west-to-east tsunami sweeping the region," Hans Kluge, WHO regional director for Europe, said in a briefing Tuesday.
He cited the Institute for Metrics and Health Assessment forecast that most Europeans could take it within the next six to eight weeks. The latest Covid surge has resulted in fewer symptomatic cases and lower death rates than in previous waves, fueling optimism that the pandemic may subside.

Herd immunity via exposure to the pathogen is not a thing. Because of mutagenesis, which is fast enough in the immunorobust population, but which is also greatly accelerated in some immunocompromised people, in particular late stage HIV with out medication.
So if everyone gets immunity from exposure, the # of mutation events will be so high that some of those will create strains with immune evasion against the ancestral strain.
Herd immunity is only possible from nonpathogenic exposure - vaccines.

Pathogenic means disease-causing. If a virus does not cause a disease, in most cases nobody will even know if they've been infected. Therefor it is impossible to know if herd immunity has been achieved.
You are implying than vaccines and nonpathogenic exposure are the same thing. That is not true.

Pathogenic means having to do with a pathogen, which is something capable of causing disease, even if it doesn't always cause disease.

Vaccines that aren't live virus are definitionally nonpathogenic.
Disease which is not diagnosed is still disease. Cancer is a disease even before effects are so obvious that a diagnosis is sought.
We have ample evidence showing multisystem impact across all survivors. Look at the brain mass data, or the vascular biopsies. Just because these may not always be so severe that the person seeks a diagnosis, doesn't mean they aren't real.
It's actually trivial to know. Does the sigmoid level off without a driving countermeasure, and then cases go to zero? No? Then it's herd immunity.
But we will not see that with COVID, just like we will not see an unbiased coinflip get heads 200 times in a row, before the universe winks out. The statistics are simple and clear. We have no herd immunity vs rhinoviruses nor influenza, etc.

We do not have heard "immunity" from those viruses, but having been exposed to them provides a certain level of protection for variants we will be exposed to later. Usually, a person will be exposed to these viruses as a child and thus will train his immune system on it to provide protection against the worst effects should they catch it again later (or maybe just be largely immune to it). Suffice it to say that the worst part of the coronavirus is that older people did not have prior exposure to it and they are the most vulnerable population to any sort of health problems that can be exacerbated by a viral infection. The coronavirus is endemic now and just about everyone will have some level of protection from having caught it.

Wrong, if the immune system didn't recognize the antigen there would be no antibody production. "Early Covid symptoms are no different to minor side effects from vaccines". [dailymail.co.uk]
Correct.
Yes we do, in the form of cross immunity. Get it? [cnbc.com]

I think you don't understand what pathogenic means.
Unless you mean that some people have side effects from vaccination, and you're calling that a disease? But that's garbage - a bruise isn't a disease, either. No, no. You simply don't understand. Please revisit basic concepts and definitions before trying to sit at the adult table.
...No, we don't. We definitely, 100%, do not have herd immunity vs rhinoviruses or influenza. If we did, they wouldn't be endemic.
Cross immunity is another thing altogether and bringing it in here is like bringing Valencias into a conversation about the best apple.
I really do, but I really don't think you do!

I do. You don't understand that vaccine side effects are (usually) mild disease from the introduction of an immunogen derived from a pathogen, this is what generates the immune response and protects you from more serious disease. It's how inoculations work. [doctorsreview.com] If an antigen were non-pathogenic, there could be no immune response.
Why do you think immunity prevents infection, symptoms or transmission? It simply means the immune system can mount an effective immune response.
The key word is "immunity", there may be a clue there. Previous infection and vaccination are both forms of active immunity. Was the vaccine designed for Omicron or do these antibodies infer cross immunity comparable with infection from a previous variant?
Pffft!

Wrong, herd immunity is achieved via interaction with cross-immunity. [nih.gov]
How's that working for you? Ohh, wait the vaccine was developed against the original lab-escape variant. Guess that's cross-immunity too so your claim that herd immunity via exposure (to the pathogen or the vaccine) is not a thing is complete and utter bullshit!

That study doesn't say what you are implying it says. If India had achieved herd immunity in Dec 2020 then they wouldn't have had waves in 2021. Which they had. That study indicates herd immunity against the ancestral strain which is NOT what we mean by herd immunity in a conversation about Omicron or other variants.
Can we get a "logic fail" mod please? Did I say cross-immunity was impossible? No, I said herd immunity for n-CoV-19 is impossible because of the rate of mutagenesis.
Maybe you've missed the part where immunocompetent people have had second and third cases of COVID-19? Maybe you've missed the part where the mutation rate per host is high enough, and the # of humans in the world is high enough, that the derease in the exponent from exposure is overwhelmed by the increase in the exponent from mutated advantages?
It's not fucking hard math.
And you prove that you're a troll by equivocating exposure to vaccine and to virus. We have lots of evidence showing that vaccine immune response is stronger than post-infectious. First page of google scholar results.

For the record, yes, I do agree with it as anything that does not kill you makes you stronger. Vaccine has to be close to 100% effective to work or it is worse than natural infection. That's why most vaccines are 100% and no AIDS one was ever approved.
This is, off course, for the population. As an individual I do benefit from covid vaccine and had three of them already.
