Clinical narrative: embolic stroke; blood clot; His major issue was speech and wasn't able to formulate any words; left sided weakness on his leg; This is a spontaneous report from a contactable nurse (patient's daughter). A 79-year-old male patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE), via an unspecified route of administration on 30Mar2021 11:00 (Batch/Lot number was not reported) as 2nd dose, single dose (at the age of 79-years-old) for COVID-19 immunisation. Medical history included transient ischaemic attack (TIA) from 2019 to an unknown date, mild hypertension, idiopathic neuropathy: in the left leg, started in the beginning of the year from 2019, melanoma removed in the 1970s, enlarged prostate, neuropathy, cholesterol and fluid retention. Ongoing concomitant medications included tamsulosin taken for enlarged prostate; gabapentin taken for neuropathy; candesartan taken for hypertension; pravastatin taken for cholesterol; acetylsalicylic acid (BABY ASPIRIN); and furosemide (LASIX [FUROSEMIDE]) taken for fluid retention. The patient has been taking all of his meds for quite some time, over 5 years. The patient did not have prior vaccinations within 4 weeks. The patient received the first dose of BNT162B2 on 09Mar2021 10:30 for COVID-19 immunization. The patient completed the Pfizer COVID vaccine series, the second shot was on 30Mar2021. On 09Apr2021, the patient had an embolic stroke. The patient's daughter stated that the patient has a history of TIA in 2019 and was concerned. She does not know if it was related. She added it might be that if people have previous risk, there may be some precautions, like to take a full dose of aspirin before, a week before. She sent an e-mail last 05May2021 and hasn't gotten a response back. The patient went to the ER due to embolic stroke and was in the hospital Friday (09Apr2021) through Wednesday. The patient went to the stroke rehab center for 3 weeks. The daughter clarified that the patient was in the hospital until 14 or 15Apr2021 before being transferred (also reported as 5 or 6 days and in rehab for three weeks). Then was discharged last 06May2021. The patient's condition seemed to be getting better. His major issue was speech and wasn't able to formulate any words. He was able to speak now. His rehab would be a lot of neurological rehab and speech therapy. The patient previously had left sided weakness on his leg from some random thing that happened. It didn't seem to get worse. It really affected his speech and cognition. The patient's daughter thought that the embolic stroke was related to the Pfizer Covid vaccine and added that thought was in some way but cannot say in what way. She thought that it exacerbated some type of blood clotting. She stated that he never had blood clotting issues before and was the type of person that would take a baby aspirin and get a nose bleed, he was the opposite of a clotter. An MRI in the hospital showed blood clot and stroke. He had blood work but does not know what it showed and presumed he was fine (unknown results). He has never really had any kind of blood work issues and does not know why he was on cholesterol medication. The patient required emergency room visit for embolic stroke. The outcome of the events was unknown.   Information on the lot/batch number has been requested.; Sender's Comments: Considering a plausible temporal relationship and known product safety profile, a possible contributory role of suspect product BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE) to the reported "embolic stroke" cannot be excluded. Previous medical history and Old age is a risk factor for the onset of stroke. The impact of this report on the benefit/risk profile of the Pfizer product is evaluated as  part of Pfizer procedures for safety evaluation, including the review and analysis of  aggregate data for adverse events. Any safety concern identified as part of this review,  as well as any appropriate action in response, will be promptly notified to regulatory authorities, Ethics Committees, and Investigators, as appropriate.
