Dh got his booster at about the 5 month mark. He was sick from the booster. He had bad body aches and flu-like symptoms for 2 days. He had supported the initial 2 vaccinations find so we were surprised at his reaction. All 3 of his shots were Pfizer.

I got my booster about 10 days ago. I got it on the same day as my flu shot which was super convenient and there was no line (yay!) but I felt like crap afterwards for a day. And my arms and shoulders were so sore. I had received the Pfizer vaccination initially but opted for the Moderna booster.
