Clinical narrative: stroke; very, very severe nausea and vomiting; very, very severe nausea and vomiting; dry heaving; dizziness; numbness/numbness in his face and arms; feeling like everything was spinning; fatigue; felt cold; slightly dehydrated; His blood pressure was elevated; This is a spontaneous report received from a contactable reporter(s) (Consumer) from medical information team. The reporter is the patient.  A 26-year-old male patient received bnt162b2 (BNT162B2), administered in arm left, administration date 10Feb2021 15:30 (Lot number: EL8982, Expiration Date: 31May2021) at the age of 26 years as dose 2, 0.3 ml single for covid-19 immunisation. Relevant medical history included: "Allergic to pollen" (ongoing), notes: Onset Date: His whole life as long as he can remember since he was a kid.; "his eyes get itchy" (unspecified if ongoing), notes: Pertinent Details: As long as he can remember when spring hits his eyes get itchy.; "coffee every so often" (unspecified if ongoing); "drank alcohol on occasion" (unspecified if ongoing). There were no concomitant medications. He took no products or medications but drank alcohol on occasion, on weekends while out with friends he would have a drink; and maybe, he doesn't know if counts but he also had caffeine, like coffee every so often. Dad has hypertension. Vaccination history included: Bnt162b2 (1st Dose , Lot: EL3246, Dose: 0.3mL injection to left arm around 15:00.), administration date: 19Jan2021, when the patient was 26 years old, for prevention prophylaxis, reaction(s): "no adverse effect". No vaccines administered on same date with the Pfizer vaccine considered as suspect. No prior vaccinations (within 4 weeks) within four weeks prior to the first administration date of the suspect vaccine. No AE(s) following prior vaccinations. Caller states he has had two doses of Pfizer BioNTech Covid-19 Vaccine. Caller states second dose was 10Feb2021. Caller states he suffered a stroke on 17Jul2021 at 26 years old. Caller asking if Pfizer has any data relative to stroke being associated with the Pfizer BioNTech Covid-19 Vaccine. Caller asking if the Pfizer BioNTech Covid-19 Vaccine is associated with any side effects related to the heart. Caller mentioned that he knows if a person has atrial fibrillation that can put them at higher risk for a stroke. Caller states he wants to get a booster dose of the vaccine, but was nervous and unsure whether his stroke could be related to the vaccine. They could not find the reason for him having the stroke. There was nothing wrong with his heart or anything else wrong. His cousin called 911 and patient was taken to the emergency room department at (Hospital name withheld) where he was admitted to the hospital. Patient reported his initial presenting symptoms were very, very severe nausea and vomiting. He thought he had food poisoning at first but it was just very, very severe nausea, vomiting and dry heaving. After that that led to more dizziness and also had the numbness; but the nausea and vomiting came first. He also felt like episodes that occurred a couple hours before the very, very severe nausea and vomiting started: when he left gym he remembered feeling like everything was spinning, felt like he was leaning to one side and couldn't lean to the other side. He had to stop; but then it kind of, that feeling kind of went away; but he still felt fatigue. When he got back to his motel the nausea vomiting and numbness started. It was numbness but he had no weakness, like he could still move his arms and face, but they were numb and felt cold. Those are the initial presenting symptoms. Outcome initially reported as recovered completely from events, no lasting effects, no residual effects that he is aware of; Caller then clarified that he had some numbness in his face and arms and thinks that lasted for a while. As for the symptoms he had the numbness which mostly went away after the first couple of days, but was still going on a little after he was discharged from the hospital. He was able to walk, speak and everything by the date of discharge. All of the symptoms associated with the stroke have gone away, did recover completely. For treatment when he got to the hospital they gave him something to control the nausea but he does not know what the name of the medication was; it was some anti-nausea medication but it wasn't like a typical one like Zofran or anything like that. They also gave him IV fluids because he was slightly dehydrated. Those are the 2 things he remembers getting when he first got to hospital. After they said it was a stroke they then put him on Aspirin 81mg and Atorvastatin 40mg. His blood pressure was elevated too so they put him on Lisinopril 10mg. They may have given him, he thinks they may have ordered a Zofran just for his couple of remaining days as needed if he had more nausea but he didn't take that daily, think maybe once or twice. The patient was hospitalized for the events (start date: 17Jul2021, discharge date: 21Jul2021, hospitalization duration: 4 day(s)). The events were evaluated at the emergency room visit. The patient underwent the following laboratory tests and procedures: 18Jul2021: MRI of the brain without IV contrast: Findings: Brain parenchyma: there is a small focus of edema and restricted diffusion measuring 6mm at the left pontomedullary junction. No susceptibility artifact to suggest hemorrhage. Negative for focal mass effect or midline shift. White matter: single tiny white matter hyperintensity in the left parietal lobe white matter which may be related to a dilated perivascular space. Atrophy: none. Vessels: major arterial vascular flow voids a pair preserved. Everything else was negative: Extra-axial spaces: no Extra-axial collections. Ventricles: negative for hydrocephalus. Midline structures that said normal pathology. Pituitary gland, Infundibula and the optic chiasm were unremarkable, everything else is just unremarkable. Impression: 5mm linear acute infarction in the left pontomedullary junction. 18Jul2021: MRA of the brain head without and with iv contrast: short version: Impression: normal. 18Jul2021: CT of the head and CTA of the head and neck without and with iv contrast: Impression: CT of the head no CT evidence of mass lesion, acute intracranial hemorrhage or large territorial infarction. CTA of the head: patent cerebral arteries, no large vessel occlusion, slow limiting stenosis, dissection, aneurysm, or vascular malformation. CTA of the neck: patent major cervical arteries with no large vessel occlusion, slow limiting stenosis, dissection, aneurysm, or vascular malformation. 21Jul2021: MRI of the brain with iv contrast: They did not see anything else, nothing relevant to report. They did a work up, they did a lot of work and couldn't find the cause of the stroke. They looked at his heart, did an echo, blood work, all of that seemed normal. No sign of hypercoagulable state on his blood work checked Factor V Leiden and blood type all negative pretty much, nothing relevant found. The outcome of the events was recovered in 2021.  No follow-up attempts are possible. No further information is expected.
