I got the booster back in January 2022 when The Omicrom variant was wiping out our whole night shift unit. 12 hours after getting it I woke up crying in pain from my head to my toes. I had a relapse that lasted about 3 days before I could get out of bed. I have not had any boosters since then and doubt I ever will.
It's a personal choice of course and no one can really make that decision for you but from my experience Im just too scared.
