A 69-year-old male patient received the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE; solution for injection, Lot Number: EN6201), via an unspecified route of administration, administered on the right arm at the age of 69 years, on 18Feb2021 16:00 at a single dose for COVID-19 immunisation. Medical history included known for a history of heart disease, stage 4 kidney failure and polycystic disease. He had been bleeding from the kidneys for a week prior to receiving the vaccine, heart attack and cholesterol. He stated he needs some reassurance and added he has Stage 4 kidney failure with polycystic disease. He already consulted with his heart doctor and kidney doctor and they say get the vaccine. He mentioned that every now and then he gets blood from a cyst rupture. On the day of the first shot he was having a little bit of bleeding in his urine. Concomitant medications included acetylsalicylic acid, ascorbic acid (ASPIRIN [ACETYLSALICYLIC ACID;ASCORBIC ACID]) taken for cardiac disorder; atorvastatin (ATORVASTATIN) taken for blood cholesterol abnormal; amlodipine (AMLODIPINE) taken for blood pressure abnormal and multivitamins. The first shot knocked him on his butt. He slept for two weeks then he started to pass blood clots in his urine. He read that the vaccine can cause clotting and he doesn't know if that might have caused the clots right after the shot. He just needs someone to hold his hand about getting the second shot. He has to leave in a couple of hours to get it. He was asking do we see a pattern where people have had a bad first reaction with the first shot and they don't have a bad a reaction the second time around. He clarified he received the first dose of the Pfizer COVID 19 vaccine on 18Feb2021 at 1600 in the right arm. He was fine until Saturday (20Feb2021) when he woke up nauseous; really tired; could not get out of bed; and then really didn't do anything for two weeks. He added he couldn't stay awake even sitting up in his chair. He couldn't eat anything because the sight or smell of food made him gag, even in the grocery store. He added he also noticed he started to get the blood clots in his urine the second day after the shot (20Feb2021). On 19Feb2021, he mentioned he had a bruise on his arm about the size of a half dollar where he got the shot and he usually does not bruise. He stated he felt like he had all the symptoms of COVID. All of these symptoms lasted two weeks. When he finally felt better the only thing he wanted to eat was a burger and fries. He is still bleeding but it is not clotting anymore. The clots only lasted about a week. He also thought he was having a heart attack, but was too tired to go to the hospital.
