Clinical narrative: Itchiness all over her body; Weird taste in her mouth; dizzy; The initial safety information received was reporting only non-serious adverse drug reactions. Upon receipt of follow-up information on 12Apr2021, this case now contains serious adverse reaction. Information processed together.  This is a spontaneous report from a contactable nurse (patient). A 39-year-old female patient received the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE lot number: ER8735) via an unspecified route of administration, administered on the left deltoid on 31Mar2021 18:00 at a single dose for COVID-19 immunization. The patient had no medical history. Family medical history included that her dad has severe allergies. There were no concomitant medications. On 31Mar2021, after 1st dose of the Pfizer covid vaccine, she experienced weird taste in mouth and felt little dizzy both went away immediately, not too concerned. Saturday 03Apr2021 until Saturday 10Apr2021, had itchiness all over her body, she was asking since she had a mild reaction, when she goes next week, if it will be really bad. It was really bad itching, she didn't think it would go away. Patient thought she had a reaction to the first dose of the covid vaccine, it was not deadly. She was trying to figure out if it was safe to her to get the second dose of the covid vaccine next week. Itchiness all over her body: The only place she did not itch was her hands and feet. Her scalp, back and everything itched. She mostly itched on her torso and scalp. She even itched inside of her ears. She does not take any medications. She was healthy. She has no known drug allergies. She has not started any new products. She kept going about her business, but the itching was getting worse and worse until this weekend. Last Wednesday, 07Apr2021, the itching was so bad that she took a Benadryl to see if it would help. She does not like to take medications. She also used calamine lotion. She took Benadryl children's dose and it did not help the itching. She thinks that the dose was 10mg, but she does not know for sure. It was a new package, she had just bought it. Benadryl children's dose did not help at all. All of a sudden, the itching resolved on Saturday, 10Apr2021. She was out a lot in the sun all day Saturday. The sun seemed to help, she does not know if it was related. She did not have any hives. It felt like chicken pox to her but with no pustules. The itchiness all over her body was awful. She does not know. She has never had anything like this happen to her before. Her concern was if she had a mild reaction to the first dose of the covid vaccine, what was going to be like whenever she goes next week for her second dose of the covid vaccine. She was asking if it will be really bad. She was itching so bad that she took a Benadryl to see if it would help. She took Benadryl children's dose and it did not help the itching. Event itching was reported as serious, medically significant. After reviewing call recording, patient reported when she was at the vaccine facility nothing really major happened, she had a little bit of a weird taste in her mouth, nothing strange. She did get a little bit dizzy but nothing that did not wear off shortly thereafter, so she went about her life normally. The weird taste and dizzy feeling started within minutes of receiving the vaccine. The events did not require a visit to emergency room and physician office. She was lucky enough to work with doctors, so she just talked to them. The patient did not receive any other vaccines within 4 weeks prior to the COVID vaccine. The facility where the vaccine was administered was in a pharmacy. There were no additional vaccines administered on same date of Pfizer suspect. Outcome of the event itchiness all over her body was recovered on 10Apr2021, while the other events recovered on 31Mar2021.; Sender's Comments: Considering the plausible drug-event temporal association, a contributory role of the suspect product bnt162b2 to the reported pruritus cannot be excluded. Case will be reassessed upon receipt of additional information. The impact of this report on the benefit/risk profile of the Pfizer product is evaluated as part of Pfizer procedures for safety evaluation, including the review and analysis of aggregate data for adverse events. Any safety concern identified as part of this review, as well as any appropriate action in response, will be promptly notified.
