tender; Could not walk; clammy; fever; loss of coordination; Chills; Dizziness; This is a spontaneous report from a contactable consumer (patient herself). A 70-years-old female patient received first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE; Solution for injection; Batch/Lot number: EN6199, Expiry date: 30Jun2021, NDC number was not reported), via an unspecified route of administration, administered in Arm Left on 04Mar2021 13:35 (Age at vaccination 70-years-old) as dose 1, SINGLE for covid-19 immunisation (clinic). Medical history included asthma from an unknown date and unknown if ongoing Patient's Medical History (including any illness at time of vaccination): asthma, about 30 years ago she had a beautiful Persian cat that she developed asthma from, but she hasn't had problem with asthma for about 20 years. The patient's concomitant medications were not reported. Caller is calling about the Pfizer COVID 19 vaccine. Something peculiar happened and she is not sure if it is related, and she knows they are still gathering a lot of data, so she wanted to report it and maybe help to tell if someone has experienced this she does not know if it is related but there is no other explanation. She is a healthy adult; she is strong and active. She is 70 years old. She got the vaccine 04 Mar and what happened to her was 6 days later which she knows is long for an adverse reaction, but she went to bed the night of the 6th day, all day that day she was fine, it was a normal day, she had no reaction to the vaccine up until that point other than just some tenderness where the injection was made but that's it. She went to bed that Wednesday night, it was 6 days after 04Mar, she woke up around 3 AM to go to the bathroom and she realized she was clammy, she had fever and chills on 11Mar2021, but the disturbing part was that she tried to stand up and got incredibly dizzy. She had to hold on to furniture to get the bathroom without falling. She said well she has a fever she better take an Aspirin, and this was really concerning, she tried to open the medicine cabinet and she couldn't seem to grab the bottle, she had like a loss of coordination, she tried to reach for the bottle and her hand couldn't quite get it. She had a hard time getting her hand to close around the bottle, she had trouble opening it. She had to try 3 times before she was able to hold on to one Aspirin. She made her way to the kitchen and had the same problem getting water in the glass. She could not grab things or coordinate anything, she finally got water and took the Aspirin and went to bed and she was so relieved to be back in bed. She woke up Thursday morning so that morning had been 1 full week since the vaccine. She felt perfectly fine that Thursday morning, it was like nothing had happened at all. She does not know if what happened was related to the vaccine but it was so far out of the norm for her so she would like to know if other people might have had this experience so far. She would prefer not to use the email. She has gotten a lot of strange email from some of the opportunities that she signed up for to increase her chance to get an appointment. She does not think she wants to provide that information. Her doctor retired and she got a new doctor before COVID struck and she has only met with her briefly, they haven't had a full visit. She is not sure of the zip code. It is not her usual clinic, she had to drive quite a ways away to get it. She would have to say the disorientation and dizziness was so upsetting that she thought does she need to call the paramedics, but she made it back to bed and she fell asleep. She started breathing to relax and then she fell asleep, and everything was fine. Description of complaint: Caller is reporting about the Pfizer COVID 19 vaccine.
