A 34-years-old male patient received first dose BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, batch/lot number: EW0177) via an unspecified route of administration in Arm Left on 25Jun2021 15:30 as DOSE 1, SINGLE for covid-19 immunisation. Medical history included covid-19 from 2019 to an unknown date doctors believe I had Covid-19 in 2019, neoplasm malignant from an unknown date and unknown if ongoing. The patient's concomitant medications were not reported. The first dose of the Pfizer vaccine was on 25Jun2021, I have got this kind, out of order. So, he said from what he remembers that he was fine following the vaccination, and everything was good but he took a few steps and collapsed. He started having a seizure and he said, my mom said, you stopped breathing, I was unconscious, tightness of chest I can breathe but it's like I cannot get any oxygen it's like very hard for me to get air. He says, the doctors there, the doctors, he says don't get me started on the (sentence incomplete) and he went to the hospital and was there for like 5 hours and they gave him 5 mg of Valium treatment and he said that was it. They could not find his vein, they did an ultrasound, I guess to find his vein and apparently, he had a couple of seizures. He says, I don't recall, all I remember is waking up in a hospital and I received the Pfizer vaccine first dose and then he said, 3 days ago, technically, I got Pneumonia vaccine which he said he received the PPSV23 vaccine prior the same day of his Pfizer vaccine. Also, he says, I hate needles, so I got tortured. I had the pneumonia vaccine (PPSV23 vaccine) first, he was with his mom, they went out for a while and then went back to where he got the Pfizer vaccine following that (PPSV23 Vaccine). He said, he was there after the Pfizer vaccine for about 30 minutes, got up and had a seizure and he says, that also his mom said that he cannot remember anything because he was unconscious, and they took him to the hospital. Also, he said, he lost his sense of taste, I cannot smell, he said, he was feeling like tingling sensation in his hands like numbness and left arm hurt a lot and hand was swollen. In 2019, he says, he got sick with respiratory issues. He was not sure if he had Covid because they did not know about Covid at that time when he was in the hospital then (consumer had respiratory issues before getting the vaccine, hence not captured as event). He said, it was freaking him out and he was scared to take the second shot. He said, he does not know if this was the combination of getting two vaccination and he says, he used to have cancer (not clarified further, hence not captured as event) and then he says, that they did blood work, it was been followed by the place and they did not tell me anything about the blood work. He says, should I be considered or concerned about getting the second dose of the vaccine because I am experiencing various symptoms and what can I do about my side effects because he is still experiencing metallic taste, loss of smell, fatigue, coughing of Phlegm, having a hard time getting to sleep. Then he says, I forgot to mention, I could feel my heartbeat and I have a cough, I have had a cough from very long time when doctors believe I had Covid-19 in 2019 (further clarification unknown). He wanted to know how safe the vaccine was. Therapeutic measures were taken as a result of seizure, unconscious, passed out. The outcome of the events was unknown.  Information on Lot/Batch number was available. Additional information has been requested.
