Stop in for a cup of coffee

I got the Moderna shot, no side effects except sore arm for 2 days. Booster April 4th ish.
I got the Pfizer. First shot arm was sore, (like x10 of a flu shot.)but I think part of that was cause I went to work right after I got the shot. Got shot at 1:45 and arm started hurting bad around 9 PM thru most of next day. Second shot I was less sore, but it comes back a little randomly every few days.
Wife has a friend in Florida that is a home care nurse. She has 2 elderly patients that are having extreme digestive problems begining right after getting second Moderna shot. Obviously they had previous conditions that she was seeing them in the first place, so as others said - reaction varies alot with the individual.
