Around half of my immediate family members had pretty bad reactions to the booster (fever/chills, aches for several days). And all of them got omicron anyway and had the same symptoms as family members who hadn't gotten the booster. I'm debating getting the booster but part of me thinks "why punish myself with high probability of fever/chills if in all likelihood I'm just going to get omicron anyway and suffer the same symptoms as everyone else"
