don’t understand why that is a difficult or controversial question
But no one has said this @BeethovenNinth ? Indeed the entire conversation has been posters trying to understand what you are looking for. I'm not sure why you're being so defensive to people who are just trying to work out what you're asking so they can give you a decent answer.
are there any studies being done considering the outcomes of post omicron mutations in the unvaccinated, recently vaccinated or twice vaccinated?
In particular, my concern relates to initial concerns I had (as a dumb non scientist) that the response to newer mutates variants may not be as strong as people infected naturally.
This doesn't make complete sense to me, but based on the the rest of your post I'm assuming you're asking why no-one has looked into how vaccination status from the initial roll out (so ~2 years ago) is associated with outcomes from infection currently.
This is because what you're asking for isn't logical - it would not be possible to conduct a study looking at what you're asking for, nor would it make sense to do so.
Firstly you're suggested that immunity is a "locked in" binary process - someone either has immunity from a vaccine or an infection. This is not true. Vaccination does not stop someone from gaining immunity from subsequent infections - instead it just allows them to gain this in a safer way as they have a level of existing protection before exposure. There have been many many papers published looking at hybrid immunity, which pretty everyone who has been vaccinated now has. Secondly, we know immunity wanes very quickly - protection from a vaccine 2 years ago is unlikely to be having significant benefits to currently circulating variants.
Vaccines do not cause someone to have a worse outcome when later infected with the pathogen months or years after it was recieved. There is potentially some risk of increased symptoms if you are infected & vaccinated simultaneously, but this would be something that occurs at the time.
As has been said previously, these fake claims are something that has been pushed by for-profit anti-vaccine groups for decades (long before COVID) and continues to be promoted as a way of making money and scaring people from being vaccinated.
