I was lucky & haven't had any trouble from my 3 vaccines. I did take my husband with me for the first 2 shots. 3rd shot, I went on my own & have done well, Booster did give me aches & pains with a low grade fever. Otherwise was fine.

No the vaccine didn't cause any seizures for me but I still ended up getting covid and had a seizure from it

I have not!

No ,all 3 of my vaccines were fine .In fact I had the first one when I was having a day of partial seizures My husband came with me

i did not get the 1st vax because i have a permeant weaken immune system since birth and when i had the kindergarten vax (1989-1990), it triggered my illness which triggered my seizures.
having said that... mom works with drs (a billing office that doubled as a drs office) and i sometimes help. and i have seen it all. covid 19 vax people that has covid almost immediately after the shot, that were fit and health that now are too weak or have died, fat people or obese people that has new underlining conditioned (including seizures) and/or has blood clots in weird and scary places (liver, heart, brain, ect).
as for your question, it is vary hard to say. seizure meds will make you have more seizures with or without covid 19 vax. it is a possible, but what i can quick research it is almost imposable to tell. if you are a normal person that got vax and have seizure... that is a different story.
