I received Pfizer 12/21. I own AL’s. My Husband and my adult children got it at the same time. My Daughter (had COVID) had severe chills, body aches and fever. She said her arm hurt right after getting it. She felt she had COVID again. It lasted 3 days. My Son (had COVID) had headache, body aches, chills and fever. His lasted 4 days. My Husband day 1 reported arm soreness. Day 2 arm soreness and a little tired. Myself the injection was painless. Everyone was saying their arm was sore but I didn’t have it, until 4AM. Took Tylenol and it was fine. Day 2 mild arm soreness and VERY tired. Day 3 back to normal. We go back for booster 1/8/21
