Got the first Pfizer shot March 15th. Arm felt cold about half an hour later and a couple of hours after the shot got some moderate chills so took a hot shower for 20 minutes and was good.
Second shot was April 5th and was good all day. Woke up at 4 AM the next morning with my teeth chattering I was so cold. Then got really hot, then back to really cold. That went on for about 3 hours and I was good to go after that.
Apparently have to get a 3rd now sometime in the next 6-12 months.
