A 50-years-old non-pregnant female patient received BNT162B2 (PFIZER BIONTECH COVID-19 mRNA VACCINE, Solution for injection, Batch/Lot Number: EP6955, Expiration date and NDC number was not reported), via an unspecified route of administration, administered in left arm on 23Mar2021 as dose 1, single (at the age of 50-years-old) for covid-19 immunisation. Medical history included allergy to tree nuts and peanuts, allergy to raw fruit, allergy to shellfish, penicillin allergy (many years ago, had vomiting and gastrointestinal (GI) upset) and allergy to sulfa (all from an unknown date and unknown if ongoing). Concomitant medication(s) included zafirlukast taken for an unspecified indication, start and stop date were not reported. Patient previously took codeine and had allergy to codeine. Patient did not receive any other vaccines within 4 weeks prior to the COVID vaccine. It was unknown if patient was diagnosed with COVID-19, prior to vaccination. Since the vaccination, patient had not been tested for COVID-19. Patient was super excited to get the first dose. On 23Mar2021, within minutes (5-10 minutes) of vaccination, patient eyes went blurry, she wears glasses and took them off and blinked to adjust her vision and put them back on. Patient stated that she wears a smart watch and it showed tachycardia. Patient had a low resting heart rate that was in the 60's and her heart rate was 110-120 for about an hour. Patient had warmth of her cheeks, neck and face. About one hour after the vaccine, patient experienced immediate flushing and stated she described it to her doctor as feeling like in a CT scan with the contrast and warmth from that. Patient stated that it was her chest, neck and face and she does have a picture of that. Patient was blotchy and it came through her makeup and was red. Patient asked if she should receive the second Pfizer Covid Vaccine. On an unspecified date of 2021, patient did not go into anaphylaxis, but it was anaphylactic in nature and would like to explain and see if Pfizer can give guidance. Patient did reach out to her doctor and he was not sure. Patient stated that she said that she thought she was having a reaction and they did not had a nurse at the location, just a pharmacist, and they took her to a table and gave her a bottle of water and gave her a cold compress for the back of her neck. Patient stated that her heart rate remained high, 110-120. Patient stayed at pharmacy for about 1 hour as she drove herself. Patient was not feeling well with a heart rate in the 80's and she pulled over several times on the way home. Patient stated when she got home, she got the GI symptoms of explosive diarrhea for 2-3 hours. Patient stated that the flushing abated about midnight that night and she got the injection at noon that day. Patient stated that her provider mentioned she could take Benadryl 3 days before and 3 days after and she had read not to do that as it could cover up a reaction. Patient stated that she wants to make sure she was doing the right thing. Patient stated she did not report sooner and was sitting yesterday, and googling symptoms and other people reported reactions and it popped up and she did not know she could report directly. Patient stated she called and reported to pharmacy and thinks they did not do anything with it, and they did not ask pointed questions and doubts they did and wanted to let Pfizer know about it. Patient does have some trepidation about getting the 2 dose and desperately wants to get the 2nd dose. Patient had Doctor or other healthcare professional office/clinic visit. Patient had no treatment for all the events. The outcome of flushing was recovered on 23Mar2021, recovered on an unspecified date of 2021 for my eye sight was blurry and tachycardia, unknown for rest of the events.
