on an unspecified date as DOSE 3 (BOOSTER), SINGLE for covid-19 immunisation.; Fever of 103; General malaise; Fatigue; Nausea; Headache; Unable to actually get out of bed and walk properly without having dizziness; unable to actually even get out of bed and walk properly without having dizziness; This is a spontaneous report from a contactable nurse (patient).   A female patient of an unspecified age received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE; Solution for injection, Batch/Lot Number: not reported) via an unspecified route of administration on an unspecified date as DOSE 3 (BOOSTER), SINGLE for covid-19 immunisation. The patient medical history and concomitant medications were not reported. The patient previously took first and second dose of BNT162B2 for Covid-19 Immunisation on an unspecified date.The patient that received a three of the Pfizer shot, the booster just a few days ago and she had kind of systemic reaction not anaphylactic on two of the three (further clarification unknown). So she totally believed in information, this she was learning because we do not really had any substantial answers to any of this at this point in time so she thought everyone after an input was imperative so she did get to document that was requesting further information which she had already given it. When paraphrased the above concern, registered nurse stated, she just want to, she was going to fill this out with a report and it was the intake was incorrect from the 'get though' what was the sense of doing this and wasting her time if the intake provider can not get things right. Registered nurse further stated, "It was wonderful to get a questionnaire, that was how you were going to learn and hopefully we will get answers for this us, we were putting out arms out and getting the MR (further clarification unknown) and the vaccines that we really do not really know too much about and she did get a reaction to the last two which, she had antibody testing which showed absolutely she had no antibody in her serology  after 7 months (hence, PC filed conservatively) so that does not makes her feel very comfortable some type of immunity, so what she was supposed to do get booster at every three months and this was ridiculous, but that was her opinion. She was just frustrated because she was taking this very seriously and want to be part of the healthcare program and she saw it was just not going in the right direction. On an unknown date, the patient had a sore arm, she did not had a sore arm. She had fever of 103, general malaise, fatigue, nausea, headache and unable to actually even get out of bed and walk properly without having dizziness so these were legitimate and she know they were all in the parameters, it was not anaphylactic effect as she said before but she gave all this information, she spent a lengthy amount of time, her time and your intake personals time and this is what I get they put me down this on mail so forget it, I will not contribute anymore information to Pfizer nor do I feel I want to take any more of the vaccine if this how it is going. I had asked questions about immunity, I have had asked why some people have more robust reaction than others (further clarification unknown for the patients hence, split not made) and no one gives any type of information other than we do not know, this is still under experiment, this does not make people feel very comfortable. The patient underwent lab tests which included antibody test: no antibody (had no antibody in my serology after 7 months) and body temperature: 103 on an unspecified date.At the time of this report event outcome was unknown.   The lot number for the vaccine BNT162B2 was not provided and will be requested during follow up.
