First Covid-19 shot

Second shots or boosters? I got the J&J/Jansen single shot. Will I need a D-varient shot, and then an E? A week after the J&J, I'm still feeling mild body aches that I didn't have 3 days after the shot. Nothing big, just like I played tackle football the night before...but hey, I'm not sick and can still taste the wife's cooking....wait..!
