I honestly don't know. I'm a long term, long COVID sufferer with dreadful fatigue & frightening neurological symptoms - memory lapse, unsteady walking, changes in sense of taste & smell, nerve damage(PHN)after shingles - so the thought of introducing more of the virus into my body fills me with dread.
My GP surgery really has no clue, I've had the "do you think it's all in your head?" more than once and any online research of peer reviewed, scientific & therefore, hopefully, trustworthy information is inconclusive.
I developed shingles after the first jab and have been continually poorly since then despite having two boosters.
It has affected my life so badly and the not knowing, the lack of solid scientific evidence as to how to treat it, if that's even possible, is very frightening.
I'm a continuous experiment in trying anything to find a way forward.
