The first dose of the Pfizer BioNTech COVID-19 vaccine last Friday, on 23Jul2021. she experienced "right arm (injection site) sore if it is touched, but not enough to mention, not real soreness, unlike with others that say they felt like Charley horse in arm and it's a tiny bit itchy". also "woke up after she sweated for a long time which for her felt like a motor that's revved up higher than normal" and wanted to know if she's having a bad or normal reaction to the vaccine. she "broke a fever, woke up really hot, sweating then went back to sleep". she is "okay this morning" but felt concerned about it. These may not be all the possible side effects of the Pfizer-BioNTech COVID-19 Vaccine. Serious and unexpected side effects may occur. Pfizer-BioNTech COVID-19 Vac-cine is still being studied in clinical trials." "In general, local side effects; the ones you get on the arm where you got the shot were mostly mild-to-moderate in severity and resolved within 1 to 2 days. Side effects that you may experience throughout the rest of your body; (systemic side effects) including fever and chills were observed with the first 1 to 2 days after vaccination and resolved shortly thereafter. The Centres for Disease Control and Prevention (CDC) (independent from Pfizer Recommendations) provides information regarding "Possible Side Effects After Getting a COVID-19 Vaccine". The response below was copied on 23Apr2021. COVID-19 vaccination will help protect you from getting COVID-19. You may have some side effects, which are normal signs that your body is building protection. These side effects may affect your ability to do daily activities, but they should go away in a few days. Some people have no side effects. If you received a second shot, Side effects after your second shot may be more intense than the ones you experienced after your first shot. These side effects are normal signs that your body is building protection and should go away within a few days." "These side effects usually start within a day or two of getting the vaccine. Side effects might affect your ability to do daily activities, but they should go away in a few days. Side effects (such as fever, chills, tiredness, and headache) throughout the body were more common after the second dose of the vaccine." Referred to HCP for further guidance in case she has side effects that bother her or don't go away. She didn't really think, she might have had one slight side effect and one big one. She didn't get a (Withheld) horse just sore. It was a little tiny bit itchy last night. She broke out in a sweat and her hair was really wet. She doesn't know if it was necessary. She was already a little scared, but she went ahead and got it. The scratching didn't bother her, and she was hot and sweaty. It was kind of like a motor and revved up higher than normal. She declined to complete the report stating she is okay now.  She is a lot more concerned about getting the second, that it would be worse or the same. For the paperwork, she broke out in a sweat and went to sleep for an hour and a half. Then she woke up and sweated for a long time and she laid in front of the AC. She tried to sign in on the phone and it wouldn't accept her phone number. She wants to know if it's a bad reaction or normal. The guy who gave her the shot said she might just get a fever. The clinical outcome of the events recovered in Jul2021.  No follow-up attempts are needed; Information about lot/batch number cannot be obtained.
