his throat closing shut; he tested positive on that Wednesday and died the following day on Thursday; he tested positive on that Wednesday and died the following day on Thursday; This is a spontaneous report received from contactable reporter(s) (Consumer or other non HCP). The reporter is the parent.  A 32-year-old male patient received BNT162b2, BNT162b2 omi ba.4-5 (BNT162B2, BNT162B2 OMI BA.4-5), as dose 3 (booster), single (Batch/Lot number: unknown), as dose 4 (booster), single (Batch/Lot number: unknown) and as dose 5 (booster), single (Batch/Lot number: unknown) for covid-19 immunisation; BNT162b2 (BNT162B2), in Feb2021 as dose 1, single (Batch/Lot number: unknown) and in Apr2021 as dose 2, single (Batch/Lot number: unknown) for covid-19 immunisation. The patient's relevant medical history included: "Hypothyroidism" (unspecified if ongoing). Concomitant medication(s) included: LEVOTHYROXINE taken for hypothyroidism. The following information was reported: DRUG INEFFECTIVE (death, medically significant), COVID-19 (death, medically significant) all with onset 07Feb2023, outcome "fatal" and all described as "he tested positive on that Wednesday and died the following day on Thursday"; THROAT TIGHTNESS (death), outcome "fatal", described as "his throat closing shut".

The patient date of death was 09Feb2023. Reported cause of death: "he tested positive on that Wednesday and died the following day on Thursday", "his throat closing shut". Clinical course: Hypothyroidism was diagnosed pre-2020 and she would say maybe in 2018 as he was undiagnosed and after the fact he noted his hands were cold and put it together it may be the hypothyroidism and so was getting treatment by 2018 and this started to appear when the patient was in law school in 2016 and he was treated and they thought he was not just tired from law school but attributed some fatigue to being in school so was diagnosed in 2017 or 2018 for the hypothyroidism. This report was not related to a study or programme. The patient's significant other is a pharmacist and he got vaccinated every time they came out and got those very quickly including the 1st two that were hard to get but his significant other helped him get those so the patient had a total of 5 Pfizer covid vaccinations and he was healthy and got covid for the first time in Feb2023 and he died in a day and a half; he took a new job and he had shaken hands with people he met and then that Monday people were off sick and the Tuesday after that the patient did not feel well and then that Thursday he was dead; he tested positive on that Wednesday and died the following day on Thursday. Cause of death: covid and the caller would assume pretty obviously as they had the medical examiner to come out and everyone was like what the heck and this guy just dies and the medical examiner told them that it could take 8-10 weeks to get the autopsy back; caller states she is not great with time frames but they knew they had to move on with business and sent the patient's autopsy to the CDC. Autopsy cause of death: was covid which was the cause of death and the report talks about his throat closing shut and does not say it was the epiglottis, but the report talks about a guy in 30s so people probably think it is his heart but his heart was not inflamed like people think it would be and nobody cares about it. They did not say or think anything of it and both he and the fiance, and the caller and the caller's husband tested; the patient did not feel well on Tuesday and the caller and her husband were told to get tested and they were both negative for covid and the caller and the caller's husband are also fully vaccinated with five shots and a lot of the caller's and the caller's husband's covid vaccines were Moderna and the caller's son had all Pfizer covid vaccines. The last three shots of the Pfizer Covid vaccine the patient did not have problems with. Caller was asked for clarification on what she means by the patient did not have problems with his last three Pfizer covid vaccines and states he mounted a response to the vaccines. Her son died very quickly. The medical examiner said it will take them a year to do their determination for the patient. The patient's fiance has the patient's card for his vaccine information but the caller can say he got his doses in Feb2021 when they first released them. The patient was not a health care provider and his first two Pfizer Covid vaccines were when the first one was in Feb2021 and the second was in Apr2021 for the first series and that is when they got them done. The patient got all of his covid vaccines in the same pharmacy that is a grocery store called (Name withheld) on (Address withheld); has no phone number to provide. The patient died four days later. No Prior Vaccinations (within 4 weeks). Specific Relevant Test for Thromboembolic events with Thrombocytopenia was not applicable.
