A 73-years-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE; Solution for injection; Lot Number: EN6200; Expiration date was not reported), via an unspecified route of administration, administered in Arm Right on 13Mar2021 (at the age of 73-years-old) as DOSE 2, SINGLE for covid-19 immunisation. Medical history included breast cancer from 2011 to an unknown date, brain aneurysm in 2015, stroke, fungus allergy from an unknown date and unknown if ongoing. Patient stated that 6 years ago in 2015 she had a brain aneurysm and had to go right to the hospital because she almost died and had 10 hours of brain surgery and then she was medically put into a coma so she could rest her brain. Her neurosurgeon was scared at the surgery because her heart rate and blood pressure went way down. He was afraid that she was going to die as she had a stroke, so he gave her a real light dose of blood pressure medicine and it brought everything back. Patient stated that was why she was taking blood pressure medicine. The patient's concomitant medications included blood pressure medicine (unspecified mediation). The patient previously took first dose of BNT162B2 on unspecified date for covid-19 immunisation. Patient received her second dose of the Pfizer Covid vaccine and it went so well that she did not even feel the needle go into her arm. Later that day she experienced dizziness and abdominal pain but felt that it might have been because she ate mushrooms and stated to have fungus allergy. She also reported arm soreness to her right arm (injection side) and redness/pink area around injection site which is warm to the touch. She took ibuprofen and wanted to know if this would have any effect on the vaccine. Referred caller to HCP for further discussion. Consumer stated of receiving second vaccine, hardly even felt anything on her arm, felt just a little prick and after she asked the person if she was already given that shot, she said yeah and said she didn't even feel that needle going into her arm but went to the grocery store on 17Mar2021 (the 17th of this month) and bought these 2 sandwiches that were kind of different, had mushrooms and patient made a mistake by eating one of them because she was allergic to fungus and she called that mushrooms and said she shouldn't have done that because anyway she didn't know if that had anything to do with her shot but got real dizzy and had pain in my abdomen but anyways this morning when she got up there was a red mark on her arm where the injection went, it was kind of lightening up, it wasn't a bright red it was kind of light red but it was going into a pink color and asked if it will go away by itself. Consumer was informed about Pfizer Medical information department and was provided with the number. Consumer stated she had a little soreness in her muscle, but it wasn't real sore but it was just sore by touching and that's because probably the needle went in there and that went away but then this morning when she got up there was a little red mark on my injection site but it was not swollen and so she took some Ibuprofen this week so she could get the soreness out of her muscle which it did take that away. Consumer stated, she was on blood pressure medicine (Unspecified mediation) also, asked if maybe that would have been a something wrong there, she did not tell that girl that she had blood pressure medicine that she was taking blood pressure medicine but that would not have affected her blood pressure medicine and asked if it would have. Treatment included none. Patient was not sure about her body weight. When asked about lab test, consumer stated no. She knew they take blood from her to check her kidneys, have had that done a couple of weeks ago and stated that wouldn't be any important for it. She got dizzy then it went away, took some Ibuprofen. This morning, there was a red blotch (19Mar) on her arm on the injection site, sore arm, somewhat bleeding, pinkish. Therapeutic measures were taken as a result of dizziness, arm soreness to her right arm (injection side)/there is a red blotch (19mar) on her arm on the injection site, sore arm, somewhat bleeding, pinkish. Clinical outcome of events was unknown.  Follow-up attempts completed. No further information expected.
