white high blood cell count; pneumonia; Kidney cancer/ malignant kidney; stroke/dry clot stroke; incredible headaches; brain bleed; lost weight; This is a spontaneous report from a contactable consumer (patient). A 70-years-old male patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, formulation: Solution for injection, Lot number: EN5318), via an unspecified route of administration, administered in Left arm on 16Feb2021, as dose 1, single (at the age of 70 years), for covid-19 immunization. Medical history included ongoing Blood pressure high/Hypertension (Diagnosed 4-5 years ago). Concomitant medications included lisinopril and ramipril, both for Blood pressure high and start and stop dates not provided. The patient stated that, on 17Feb2021, he experienced incredible headaches and stroke/dry clot stroke. On 09Mar2021, experienced brain bleed. On an unknown date in 2021 had pneumonia and on unknown dates in 2021, experienced white high blood cell count and lost weight. Additionally, he described that, on 17Feb2021, had incredible headaches, he typically did not get migraines or anything, so he called his doctor. The doctor said to take Advil (later clarified and confirmed that it was Advil not Tylenol that he took on 17Feb2021 for his headache that did not work. Advil- lot, NDC, and expiration date unknown), but that did not help and if he felt worse to go to the emergency room and then he started feeling worse so he went to the emergency room and as he was being admitted he was having a stoke. He had a dry clot stroke and was hospitalized on 20Feb2021 and released in 3 days and came back home on 23Feb2021. This involved into a brain bleed and the caller was readmitted on 09Mar2021 and was in the ICU for 3 weeks and was discharged on the 25Mar2021 to a rehabilitation center. Regarding to the stroke he was not sure if it was a reaction or seeming not likely or if it was a precursor or just coincidental from having the stroke. He did not know which day he actually got it, he know when he was admitted to the hospital and was having a stroke as well. His headache stopped in the ICU and they were minimal. The caller had bad headaches with the brain bleed then with medication they helped. The caller was taking sodium tablets and was on a restricted water diet. He talked to the neurologist recently, who said that the patient was doing well and he would not think he had a stroke. The doctor told him that if he had other symptoms to go to the hospital. When he went back in after speaking with the neurologist, he had a white high blood cell count the first time and the second time instead of just giving an antibiotic for pneumonia he actually did a CT scan in 2021 and that was when noticed the mass on left kidney. On 01May2021 he went back to the emergency room. The doctor noticed it was the second time with a high blood count in 2021. They found cancer on the kidneys when he was readmitted to the hospital 01May2021. He was kept overnight, and the admitting doctor said he thought, the vaccine was what caused the stroke but that the caller also had a mass on the kidney, since had his right kidney removed and was discharged on 08May2021. He understood that cancer sometimes could make you have blood clots. He was kind of like was this a medical event that was going to happen anyway. His brother was at the home who had an exposure to covid recently so now he recently got tested (unknown date in 2021) and was negative for covid. He was scared and reached out to his PCP, neurologist, and infectious disease control to see if it was safe to resume the vaccine. He did not know if the stroke was a reaction to the vaccine but knows that strokes feed off cancer. Reportedly, he lost weight in the hospital in 2021. He did not know the dosage on his blood pressure medications because they have changed since he had been in and out of the hospital. He was started on Lipitor but the dose was down to 40mg from 80 mg. Did not think the vaccine caused the stroke (could not say that for sure), the bad news was that, he had a malignant kidney and stated further good news that if catch and remove the kidney guess it did spread. He reported that, basically brother had not been vaccinated and while he was on his back in the ICU with the kidney removal his mom passed away and they were trying to clear out the house. They definitely believed in the mandate of wearing masks and staying apart. Seriousness criteria for all the events was reported as hospitalization except lost weight. The patient was admitted emergency room for all events except lost weight. Therapeutic measures were taken for all the events as a result of incredible headaches, brain bleed, kidney cancer/ malignant kidney, stroke/dry clot stroke, white high blood cell count and pneumonia. The outcome for the events: Kidney cancer/ malignant kidney, stroke/dry clot stroke, white high blood cell count, pneumonia and lost weight was unknown, and outcome of the events of incredible headaches and brain bleed was recovered on unknown dates in 2021.
