I cannot see how another variant if Covid 19 can be classed as a good thing. I do think we have to be aware of the risks of not taking every precautions against it. Tge people not vaccinated will be tge one’s admitted to hospital and probably not come out or if they do with life changing health issues, that’s their choice, but I don’t see why other people like nurses and carers should pay the price, it’s 20 times more likely you are to catch Covid from a non vaccinated person. I won’t knowingly mix with them, continue to wear my mask in public places, got used to it now, we have to live with it.
I'm not sure where your evidence is that somebody is 20 times more likely to catch Covid from a non-vaccinated person. Do you have any links?
It's mostly speculation at the moment, but the theory about Omicron being a good thing is as follows:
It's known that the Omicron variant has mutations which mean it's more easily transmissible. It also seems to provide some immunity against all variants. Therefore, if a person catches Omicron, they won't be infected with other variants. That means that other variants will run out of hosts and will die out.
At the moment, it's theoretical. Nobody really knows. It appears that Omicron causes less severe illness, but so far most of the data comes from South Africa, which has a young population. The results might be different in the rest of the world.
To date, nobody really knows for sure how effective current vaccines are against Omicron. Scientists are working to adapt, but it takes time to do the research and trial and produce vaccines.
There is also the likelihood that Omicron itself will mutate, in which case the resulting variant could cause more severe outcomes - or maybe not.
The fact is that speculation is not very meaningful. For the moment, it would be wise to reduce risk of being infected, using all the methods people know about.
