Missing link? But you are AFAIK correct. Here is a good link:

The bottom line is, the newly released 2024-2025 formulations (as you indicate, containing the monovalent KP.2 variants of the JN.1 lineage) are a better match to the latest and greatest Flirt variants, like the KP.3.1.1. We are definitely entering the "Flu-Era" of Covid19. But that should not let us underestimate Covid19 - it can be devastating to the unvaccinated ( >>Flu, but we have had a century to adapt to the latter).
And yes, you are right on with your bolded statement - particularly the last part ;-)
In spite of my NSAID use, I have never tested positive for Covid, although my wife did, and I'm in a hospital environment ;-)
