Had my booster shot today. Moderna this time, instead of Pfizer. Also, no soreness in my arm.
Had my first Pfizer shot in November; I had some soreness at the injection site for a couple of hours, but nothing beyond that. My
second shot, three weeks later, I had the same soreness, but woke up the next morning feeling like crap. Had a fever, and body aches. It lasted the better part of a day, but was gone with 24 hours. For my booster in May, I'm probably going to stick with Pfizer just because it's the devil I know, even if it makes feel ill. I don't want to mix-and-match; my logic is that a Pfizer booster should work best atop the initial Pfizer vaccines, but I've no study or knowledge to back that claim up.
