Same as you got the Pfizer. Nurse said it was 50/50 either you get it bad the first dose and are fine the second or vice versa. I feel good other than the worst sore arm I have ever had.
Got my first dose of Moderna a little while ago, going for my second in a few more days. Yeah, the arm hurt a good bit after lol. I just made sure to keep giving it a stretch every little while and the stiffness and pain was gone in, like, 3 days.
