A 71-year-old male patient received the 2nd dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE) via an unspecified route of administration in the left arm on an unspecified date at age of 71 years old as single dose for Covid-19 immunization. Medial history included high blood pressure; heart attack in 2005 and had been fine; diabetic for years and just taking a pill for it, not that bad; covid-19 with bed sore, pneumonia due to covid. The patient had Covid back in February he was hospitalized for about little over 2 weeks and he was released, with he had double Pneumonia and that's why, he was in the hospital that long and he waited the 90 days because all the doctors said, he should get vaccinated for it. Concomitant medications included lisinopril for high blood pressure, glimepiride for diabetic, pioglitazone, prazosin, pravastatin, acetylsalicylic acid (BABY ASPIRIN), something for sugar and high blood pressure. The patient previously received the 1st dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE) via an unspecified route of administration in the right arm on May2021 for Covid-19 immunization, experienced swelling in the armpit area/swelling underneath his armpit and swelling underneath his armpit, his lymph nodes. After taking the first dose of the Covid vaccine he experienced swelling in the armpit area. With the second dose he felt dizzy, could not breath, weakness, pain in the armpit area/ arm, left side of the chest/breast area, loss of breath, like having a heart attacks, lightheaded, Dull pain in the chest which came and went. He had seen his doctors who have done some test, including CAT scan of the brain, no signs of mini stoke. He lost his memory for 2 hours; he did not know what was going on; he was answering wrong to the questions asked. His doctor told him that he will prescribe him something to calm the nerve ending like he was experiencing. After the covid virus he was feeling fine until he received the Pfizer covid vaccine. He stated his doctor told him that he read the vaccine was causing some of these problems in people. Pfizer should let the public knew about these issues. The reporter wanted to know if anyone had died due to loss of memory and chest pain after getting the Pfizer covid vaccine. He had a first one, it wasn't terrible the second vaccine he had it about two weeks ago now, he was experiencing real shortness of breath and that was 2 weeks ago and also he had a weird sensation where had a shooting pain come across his chest to his breast and he felt like he was out of breath and now he still like really-really out of breath, it took a long time to go away. The patient got the vaccine around it was 2 weeks ago. Today was the, Thursday 13. So, they roughly around the first or second you know, that's when the patient got the last shot and then he started to feel these pains around the 08Jul2021 and it just start to get worse then around the 10th, that was Saturday. The patient had 5 of them, that day and then Sunday 11Jul2021, he had about 4,5 and he was in the hospital when he was having them, he was in the emergency and then they what they done an MRI of his brain, they thought, he might be having a mini stroke and it wasn't it and the doctor said it could be the shot that got for breath and he went to his regular doctor today and she said the same thing she was going to heart doctor tomorrow but his regular doctor said she believed, it could be the shot. The patient got the second shot on left arm because he didn't wanna mess around the right arm again to get swelling back. It's on his left arm, that's where the pain started, right underneath right across from his breast okay, underneath his arm, it went, it started really the patient could feel prominent line and it's stronger and stronger and then it come close to his nipple of breast and then it started to go away and then he got like you know dizzy again and after little bit of dizziness went away and then but he was on weak side again. The patient had tones of blood work. Outcome of events: It's definitely persisting because he just spent the last weekend in the emergency room and he hadn't had these problems before. Reporter stated about treatment, "Well. He did, when he was in the hospital, he was hospitalized and they did an MRI of brain, they checked the his blood vessels in his neck and also they did a chest X-ray and they were saying because one Saturday, he lost his memory like for 4 hours he didn't know where he was, he knew who I was but he didn't know where he was why he was there, he totally didn't know what present, it was he didn't know, what year it was, like he lost everything for about you know about 4 hours I guess and about 5 O'Clock he knew everything, so they couldn't figure that out that's why, they did all these test they thought that he had like any mini stroke or something but they did rule that out." When asked if still in hospital, reporter stated, "No, he's home he was hospital yesterday. Today's what actually what was there Saturday and Sunday, and today is Monday he was released on Monday." Reporter again handed over the phone to the patient. The patient stated, "it was nothing you know and the scary part is like, my wife said you know, I lost my memory and I never had done that before either and the doctor, that ordered the MRI of my brain. He came to my room and he said to me, we can rule out that you didn't had a mini stroke, he says everything is fine. He says I really think it's the shot that you got or the one or two has caused it, he said that the Pfizer shot or the, you know, whatever he read where it does affect your nerve ending and he is saying it could have been a nerve ending or something coming from under my armpit over, but today I didn't have none of them attack but I am, my light headed and my breathing are hard, I mean, I can breathe, my lungs are okay, they took an X-ray my lungs and everything. Everything is Okay with my lungs but you know, my breathing like last night I was going to die in bed. I was breathing so, hard like I was afraid it's my breath and I came through the night but I felt the same way today and all day I felt, shortness of breath and like light headed but I didn't get any more attacks. I underneath but still like I feel like cow in other words." The patient had read, and specialist that read the MRI and both of them, they both think, It could be the shot that the patient got. Treatment was received for the events. Outcome of the events was unknown. The lot number for the vaccine, [BNT162B2], was not provided and will be requested during follow up.
