A 50-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection) (at 50 years of age), dose 2 via an unspecified route of administration on 18Mar2021 (Batch/Lot Number: EN6202) as DOSE 2, SINGLE  for COVID-19 immunisation. Medical history included blood pressure high from an unknown date and unknown if ongoing. Concomitant medication included metoprolol taken for blood pressure measurement, start and stop date were not reported. Historical vaccine included BNT162B2, dose 1 on 25Feb2021 (at 50 years of age) (lot number: EN6202) for COVID-19 immunisation and the patient experienced tiredness. She did not have any other vaccine within four weeks prior to COVID-19 vaccine. The patient reported possible adverse event with the Pfizer COVID-19 vaccine. Throughout the whole pandemic (1.5 years), she hadn't gotten any bloodwork until recently. She said that she had been hospitalized twice. Her first hospitalization was due to the high white blood cell count and the second hospitalization was due to blood in stool wherein they had to remove her bleeding polyp and she would not be discharge because of her high WBC count. When she talked to her blood doctor, her blood doctor told her that she had another patient with the same manifestation, but the other patient had COVID-19. The patient was not sure if she had COVID-19 in the past. She will have more blood work and she will have a biopsy of her bone marrow. In the meantime, she was wondering if it may be an adverse event from the vaccine. She also mentioned that she was part of the clinical trial for the Pfizer COVID-19 vaccine. The patient mentioned that she doesn't know as she had not done blood work since prior to COVID-19 because she hadn't gone to the doctor, so she went to the doctor very recently like at the beginning of May maybe. She guessed that just for something else and she went fasting so they can do routine blood work and incidentally she had a very high white blood cell count (in May2021) and at this point they cannot figure out what was wrong with her. She added that she was very healthy, everything came back pretty normal. She doesn't feel sick, they hospitalized her once for that and then she was hospitalized for (incomplete sentence). She had colonoscopy, she had some issue with (incomplete sentence), they repeated the colonoscopy to put the 'clamp' and then they didn't let her go from the hospital because of the high white blood cell count and so, she guessed she was kind of wondering, if there have been a report on abnormal blood white cell after the Pfizer vaccine and it came earliest thought in her mind today when she was at new doctor who told her about another patient that have high white blood cell count but she had COVID. The patient did not have COVID that she knows, she did not have COVID. The patient added she does not consider it a bad reaction. She mentioned that she was tired. She had undergone multiple blood tests. White blood cell count has been like from 24 to 26 all the way up to like 33. She added that when she originally went to the doctor and when she got this blood work done the first one she was having a little tiny bit of rectal bleeding in her stool and that was because she went to the doctor and she did have a colonoscopy and they basically found some internal hemorrhage as well the follicles and the second time she repeated the blood work, the third time actually she started bleeding pretty bad, so she had to repeat colonoscopy  so because of all of this trauma her doctor was repeating  the white blood 'sheet' to take blood 'today' to look at her white blood cell a little bit more in depth now that her body was kind of healed for those colonoscopy. She mentioned that now, all this medical test if there was a possibility for her to find out if it could have to do with the vaccine. She added that right now she was 5 feet 6 inches, at that time she was 6 and about 195 pounds. She lost her 10 pounds which the patient commented as "that good news". The patient underwent lab tests and procedures which included biopsy of bone marrow with unknown result on 07Jun2021, blood work and repeated the blood work with unknown result on an unspecified date; Colonoscopy on an unspecified date with unknown result and in May2021 where they found some internal hemorrhage as well the 'follicles'; and white blood cell count: 24 to 26 on May2021 all the way up to like 33 and unknown result on 07Jun2021. The "high white blood cell count" and "Internal hemorrhage/ internal hemorrhage as well the 'follicles' started in May2021 while other events started on an unspecified date. The outcome of the events was unknown.
