I got my third a couple of weeks ago. I had two Pfizer but my third was Moderna - I had a choice but the nurse suggested that Moderna had slightly better coverage as a booster for us.
I regret my choice ! It knocked me down - I had no problems with Pfizer but with the Moderna I spent the next day absolutely exhausted. I got up and had coffee and then called in to work and lay in bed, felt like crap, felt like I weighed 300 pounds. 1 in 100 get lymph node swelling in the armpit, got that too - very sore to move my arm over that lump for a few days !
Anyway, glad I got it, more coverage - but any more boosters & I'm going back to Pfizer. FWIW, I never react to immunizations...just had my flu shot.
