A 72-year-old female patient received the second dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, lot number EL9265), via an unspecified route of administration on 04Feb2021 as dose 2, single for covid-19 immunisation. Medical history included had fallen before. The patient was previously vaccinated with the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, lot number EL3249) on 18Jan2021 for covid-19 immunization at the age of 72 years old and experienced didn't have any problems, her arm wasn't even that sore. Concomitant medications were not reported. After waiting for 10 minutes at the vaccination facility on 04Feb2021, the patient stated that she left the building and "a wave" came over her (it wasn't like a dizzy spell it was like a wave that came over her), it was the weirdest sensation, and she couldn't move any parts of her body, like she was paralyzed. She informed that she did not lose consciousness but, she knew that she was going down and she just couldn't break her fall. It was like she was paralyzed, and she couldn't put her arms out to brace the fall. She couldn't move, like her total body was paralyzed and she fell full force and went on her forehead and her head bounced off the cement when she fell on her face. Her head was bleeding and she was wearing a winter coat and she was bruised on her chest and "abd"; her chest was all black and blue. It was further reported that after getting the 2nd dose, when she was walking out of the facility she fell on the concrete and her head bounced off of the cement and she had lost a lot of blood. She further informed that she had fallen before, and she can brace herself with her arms out and; with this she just thought "please don't break your nose". She then turned around and she tried to get up and she was bleeding so bad and there were people all around her. She ended up in the hospital's emergency room for 10 hours and she bled for all those hours in the hospital too. In there they had to do a CAT scan to her head on 04Feb2021 (unknown results) as the doctor felt like she could've had a concussion. Later, she told the doctor that they were going to (privacy) the next day and he gave her a list of things that she couldn't do. She added that she has a scar between the bridge of her nose because of where she hit, and they couldn't stitch that up because it was like a cookie cutter. The doctor said that it will eventually go away and if it doesn't, she was going to have a procedure done; but that wasn't her main concern anyways. She added that she also had body aches on 04Feb2021 after the 2nd dose and asked if anyone else had reported this happening. Then the next day on 05Feb2021 they had to fly to (privacy), and she was in a store and her head did not feel good like her head was in a fog on 05Feb2021. She stated that what she experienced was terrible and awful. She then asked if she should get the booster dose and asked when it will be available. She added that she knew that the booster was coming out, but she was very nervous to get the booster so, she would like more information on it and wanted to know if she needs to get the booster.
