covid booster?

Does anyone know what's happening with it?

I've tried to get to the bottom of it, looking all over including gov, but no definitive answers.

It seems like gov is hoping to kill some of us off again (like during the full pandemic), as it appears that the booster is only for over 65s, immunosuppressed, and frontline staff?

Any other health problems, like asthma etc, we appear not to be getting it?

I hear that US is offering it to all citizens, yet UK is hardly giving it to anyone and you can't get it privately either??? WTF? I'm sure they want to cull the herd again....??
