The reporter is the patient.  An 82-year-old female patient received BNT162b2, BNT162b2 omi ba.4-5 (BNT162B2, BNT162B2 OMI BA.4-5), as dose 3 (booster), single (Batch/Lot number: unknown) for covid-19 immunisation. The patient's relevant medical history was not reported. Concomitant medication(s) included: PREMARIN taken for hot flush (ongoing). Vaccination history included: Bnt162b2 (DOSE 1, SINGLE, Received 3 previous doses of Pfizer COVID-19 Vaccine.), for COVID-19 Immunization; Bnt162b2 (DOSE 2, SINGLE, Received 3 previous doses of Pfizer COVID-19 Vaccine.), for COVID-19 Immunization. The following information was reported: MYOCARDIAL INFARCTION (hospitalization, medically significant), outcome "unknown", described as "Heart attack"; CEREBROVASCULAR ACCIDENT (medically significant), outcome "unknown", described as "Stroke"; HYPERTENSION (non-serious), outcome "unknown", described as "blood pressure went to 210/110"; WEIGHT INCREASED (non-serious), outcome "unknown", described as "Weight gain"; FATIGUE (non-serious), outcome "unknown"; COUGH (non-serious), outcome "unknown", described as "coughing"; DYSPNOEA (non-serious), outcome "unknown", described as "short of breath". The patient was hospitalized for myocardial infarction (hospitalization duration: 5 day(s)). The patient underwent the following laboratory tests and procedures: Blood pressure measurement: 210/110; Checkup: never had any problem, notes: always went every 6 months for checkups, never had any problem; 20 to 30 percent blockage in two arteries, notes: she had a 20 to 30 percent blockage in two arteries which was not enough to do anything about. Therapeutic measures were taken as a result of myocardial infarction.  Clinical course: It was reported that Pfizer COVID-19 vaccine really changed her life. Had COVID-19 after the third shot of Pfizer COVID-19 vaccine. Had fatigue, was coughing, short of breath, then had a heart attack after the third Pfizer COVID-19 vaccine shot. Heart attacks are prominent in her family, always went every 6 months for checkups, never had any problem. When she had her heart attack she was in the hospital for 5 days. Diagnosed with a mild heart attack and would be treated with medication and diet. She wanted a heart catherization to find out why she had a heart attack. She has been on Premarin and does not see a connection with the events. Declined to proceed with a report at this time. Heart catherization showed she had a 20 to 30 percent blockage in two arteries which was not enough to do anything about. Considered menial by her cardiologist. Cardiologist could not explain why she had a heart attack. There were so many things involved in the vaccine. She was only explaining to the transfer agent about all the problems she had which was why she had not gotten back to enrolling in the assistance program. After she had her stroke that is when she was told she was a long term hauler of COVID-19.   The information on the batch/lot number for BNT162b2, BNT162b2 omi ba.4-5 has been requested and will be submitted if and when received.
