Upon receipt of follow-up information on 27Aug2021, this case now contains all required information to be considered valid. This is a spontaneous report received from a contactable nurse (patient) and a solicited report based on the information received by Pfizer from AbbVie Inc. (MFR control no.: 21K-163-4051163-00).  A 32-years-old male patient received first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, lot number: unknown), via intramuscular route, administered in Arm Right on an unspecified date (at the age of 32-years-old) as dose 1, single for covid-19 immunization; testosterone, via topical route from an unspecified date (Lot number: unknown) to an unspecified date, at 5 g for an unspecified indication. Medical history included XXY chromosome variant and does not produce testosterone hormones like other peoples; both are ongoing. Other medication and medical conditions included: chromosome disorder - consumer stated that he was born with extra female chromosome. He had XXY chromosome variant, so the men are born with XY, women are born with XX chromosomes. The patient was born with XXY chromosome, so he had under 200 testosterone, 30 estrogen and his body doesn't produce hormones like other peoples or 'approach systems' (Further clarification was unknown). The patient's concomitant medications were not reported. On an unspecified date, the patient experienced axillary lymphadenitis, leg pain, foggy feeling in head, tiredness, vertigo, confusion state, dizzy. Clinical course included: the patient had the Pfizer and after the first week the patient had a huge, inflamed lymph node in armpit; armpit lymph node got inflamed, leg pain and then the patient went to get the second dosage and had a more severe leg pain and a brain fog for about 2 and a half months. Patient would like to report the bad side effects. After about 2 weeks of taking it (testosterone), after the second dosage the patient started feeling dizzy which kind of sucks, feel retarded like had a concussion or stroke or high-altitude sickness like less oxygen in the brain, just feel kind of gazed or confused or feel extremely tired, tiredness, vertigo. About age consumer reported that like 2 or 3 months ago he got the full vaccine; he does not know if that matters, and its 33. (Not appropriately clarified, hence not captured in tab). About weight consumer reported that it was about 24 BMI, so he was just underneath the threshold of being overweight. (Further clarification unknown). About treatment consumer stated that while he was on Pfizer for the both terms of taking the dosage (Further clarification was unknown), he was taking Testosterone 5 gm, 1 percent (1%) Testosterone (Dosage were not appropriately clarified), a gel on both of arms but then after about 2 weeks of taking it (Testosterone), after the second dosage he started feeling dizzy which kind of sucks (Hence Testosterone was conservatively captured as suspect) because he need that medicine to basically hormones (incomplete sentence) but then Pfizer is making him dizzy so that kind of blows. So basically steroids he guess can call it (incomprehensible voice) stopped. About site of vaccination consumer stated, first one in right arm and then his armpit lymph node got inflamed, it was not inflamed by anything else, it was inflamed by the vaccine and then he took the second dosage in left arm. The pharmacist who injected it didn't clarify or specify about getting on the same arm, he told her he was getting on the left arm this time, she giggled so it doesn't matter which arm. Consumer further stated that he had symptoms such as brain fog, usually a kind of feel retarded like had a concussion or stroke or high-altitude sickness like less oxygen in the brain, just feel kind of gazed or confused or feel extremely tired. He had that about 2 months and a family member who got the Pfizer also had the same symptoms and then another family member who had patient's DNA another sibling also has the same effects. One of his friend who also got the Pfizer, patient talked to him, he also got the same symptoms (Further details were not available over the call, hence split case was not made). The patient doesn't know if there's a bad batch in (place), got like a horrible batch of Pfizer he has no clue, he do not know if it got mixed with something else (Further clarification was unknown). All had tiredness, went to sleep for 8 hours, wake up for 2 or 3 hours, and get some coffees, then were really tired, then have to lay in bed and deal with vertigo until you (incomplete sentence).
