A 50-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE; formulation: Solution for injection, Lot Number: EW0183), via an unspecified route of administration, administered in left arm on 02Jul2021 (at the age of 50-years-old) as dose 1, single for COVID-19 immunisation. Medical history included haemochromatosis, COVID-19 from Mar2020 to an unknown date (she reports she believes she had Covid in Mar2020). Concomitant medications were none. It was reported that the patient got her first vaccine on 02Jul2021. Patient within almost immediately, felt like she was dizzy, had a wave of dizziness and she laid down and just started drinking water, she got hot and started to feel warm, a hot flush, she felt like after a while. Her throat felt like she had to sit up because it felt more restricted and same with her nose after about an hour. She was sweating profusely from her feet and palms but mainly her feet and she had an involuntary tremor or shutter going through in a rhythmic cycle and she fell asleep for a really long time and didn't realize she was asleep for a while and put ice on. When she got up, she went to the restroom, was very dizzy, weak and didn't feel like she could walk there and went and they wheeled her over, she was in a gymnasium, they took her to the restroom. The patient stayed at facility for 2 hours and when she got home, she rested and drank liquids like they told, and then she discovered she was incontinent, she didn't notice at the time, she definitely noticed that. She had a loss of color and felt like she couldn't speak very well or have a conversation, she just didn't want to not speak and wanted to lay down, she just felt really bad. That was on Friday (02Jul2021) and she went to the emergency room (05Jul2021) on Monday because on Sunday (04Jul2021), she couldn't make herself get up and she thought she would go to the emergency room due to pain and to check her kidneys because they got sore and the whole back around that area started getting really sore and she started getting pain in that area of her kidneys even though she was drinking a lot of water. In ER, they did urine test and blood work and determined that my kidneys were fine. I felt really bad for 5 days, and by tenth day she felt normal. The patient reported that for a week probably she had a hard time, definitely the first 5 days. Ten days from when she didn't feel anything, and 5 days were super difficult. The event kidney pain/kidneys got sore was serious (medically significant). She's waiting to get her second dose and she's reading over the information and it looks like she's had all but one of the following allergic reactions from the first shot, so just wanted to report previous symptoms, and get medical advice to ask about that before she got the second dose. She confirms all symptoms began in Jul2021 and ended in Jul2021. The outcome of all the events was recovered on an unspecified date in Jul2021.
