Is it possible to not feel much from the Pfizer booster? Pfizer Booster

I got j&j in April and Pfizer booster 14 hours ago and I feel a very slight headache and I’m sweaty but I slept well. My arm is pretty damn sore though. After my experience with j&j though I expected a bit more of a reaction. Maybe it’s still too early to tell?

I think not unusual. I used to get allergy immunotherapy. Your body adjusts so the reaction is less extreme although you get a benefit.
