A 62-years-old female patient received second dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, lot number: FR8737and expiry date was not provided), via an unspecified route of administration, in left arm, on 07Apr2021, as a single dose (at the age of 62-years) for COVID-19 immunization. Patient's medical history and concomitant medications were not reported. Historical vaccine included first dose of BNT162B2 (PFIZER-BIONTEC COVID-19 VACCINE, solution for injection, lot number: EN6201 and expiry date was unknown), via an unspecified route of administration, in left upper arm, on 05Mar2021, as a single dose for COVID-19 immunization. The patient arm hurt after first dose (began immediately and lasted for about 4 days) which was resolved on 09Mar2021. Patient second dose was scheduled on 27Mar2021, but she did not get it till 07Apr2021. It was reported that on 08Apr2021, patient had such an awful reaction to the second dose of the vaccine. She started to get dizzy and weak, chills, everything was a blur, sweating, could not drink threw up if she tried dry heave went back to sleep and slept for 48 hours had just chills the whole time. She was in bed sleeping trying to drink, getting up to go to the bathroom and feeling like she was going to die for the next three days. She was nauseated and is still nauseated and could not drive. She took Tylenol an antiemetic at urgent care that stopped. She took Zofran with the saline solution infusion and she went home and slept. She was dehydrated and had soreness all over. On 09Apr2021, she could not roll over and had a sore on her left butt cheek that was still there cold sores on lips. She thought the sore on her left butt cheek came from laying in bed so much, and it was not in any other space but that one spot almost like she would have gotten the shot there, but she didn't. On 10Apr2021, patient felt like she was going to die, and went to urgent care and asked if they could give her fluids. They gave her fluids and Zofran and that helped a lot. This one shocked the hell out her, she thinks it was her gums that started to bleed on 11Apr2021. She had the best oral hygiene and went to the dentist all the time. She was flosses like crazy. She started to drink a ton of water and has not seen it since. She cannot guess what the reason was. On 11Apr2021, she could function a little and had chills again last night and sweating. She did not have a fever. She ate chicken noodle soup water and a little bit of ginger ale. She started to feel better, but not 100% better not even 90%, not even 80%, but was heading towards the right direction. Patient also hasn't eaten for 5 days after second dose. She experienced cold and hot. She was not complaining at all and she has been sick for days and cannot eat and will throw up but will gain it right back. The dizziness and weakness were subsided. She feels like she is getting beat up but is recovering. Patient thought that vaccine pulled out with a syringe and that's the problem everyone gets the same dose. Patient's weight was 136 or 138 lbs. Outcome of the events nauseated after second dose was resolved on 10Apr2021, and dizzy and weak after second dose was resolved on an unknown date in Apr 2021, and for the events chills and sweating it was recovering, and for all other events, it was unknown.
