A 38-year-old female patient (reporter's daughter) received bnt162b2 (COMIRNATY), dose 1 via an unspecified route of administration in Apr2021 (reported as between Mar2021, Apr2021, or May2021) (Batch/Lot number was not reported) at the age of 37-year-old as single dose for covid-19 immunisation. Medical history was not provided. Patient never smoked. Patient's mother has lung cancer because she was a smoker for 40 years, doesn't have COVID but it hurts to breathe in, as long as she is sitting she is okay, doesn't go anywhere because of her illness, she had the two with Moderna COVID vaccine, had hers after her last radiation in Apr2021 and her eyes had a rash and she couldn't go to bed, had lost 3 pounds because she couldn't eat, she had radiation and she shouldn't of mixed both but no one told her that. Concomitant medications included antidepressants. Patient had the first dose of Pfizer Covid vaccine somewhere between Mar2021, Apr2021, or May2021, but since this she's had different CT Scans which show that 1 lung is half way dying. Patient did not smoke or did drugs and that her daughter went back for another scan and it showed that it had jumped to the other side, she's having a lot of back pain. Before Pfizer Covid vaccine, her daughter was 120 to 140lbs and is now 170 to 180lbs, her face is swollen, she did not eat, she will go all day without eating, but she got big and her face is swelling. Patient had never smoked, she got the vaccine mid Apr and her lips were swollen. She was always been 120lb to 140lbs and now she was not doing nothing and she put on weight, she's more tired, not feeling good. People have asked if she is pregnant, how that makes her feel? She doesn't eat because of that and if it is late in the evening she will just have an iced coffee or whatever. No one gains and loses weight like this unless you have caner and are sick. Patient is gaining weight because she is sick and has blown up like the reporter's sister was when her liver had failed. She had pneumonia the first time, went to hospital, she had blood clots-she's on medicine for blood clots, her back is kicking where your lungs are, she's on oxygen, can barely work, she's worse off than the reporter who had cancer, she was perfectly fine--ambitious, outgoing, her eating habits have changed, putting on weight, swelling up, lungs are black, never had this issue, the reporter did not know if it's blood clots. She's having headaches. The reporter sated she was not going to lose daughter over this, she's 38 years old, never had a blood clot. The weight gain is because she's tired. She never takes medicine and is on antidepressants pain medication for her back. She was coughing up blood, reporter thought she's got pneumonia. Patient has been sick since she got the Pfizer COVID vaccine. Her daughter has been in and out of the hospital and has been to the urgent care and she has been down for a long time. Patient had a cat scan and one lung looked like half of it was dying and she doesn't smoke and never has. Patient has never had these problems before and she has never had trouble breathing. Patient is trying to go to work and she can't breathe. Patient got another cat scan and it looks like it jumped to the other side of her lungs and she has a lot of back pain. Reporter knows that her own lungs are in her back because that's where she had surgery before to take her lung out from her back and now when she breathes in her back tightens up. Patient doesn't have cancer but her lungs are deteriorating ever since she had the vaccine and it has made patient complain about her face being swollen and it is a disaster. Patient's face swelled up and she was down for a week with this. She had went to the emergency room and that is when they had noticed that her lungs were turning this way and they had put her on something that was supposed to be for blood clots, this gave patient blood clots, at least that's what it sounds like. Patient has had a collapsed lung and she has blood clots and her lungs are bad. Patient was put on Cialis or something for a blood thinner or whatever to help the heart beat. Patient had called the reporter crying at work because she couldn't breathe and she can't stand up and the reporter doesn't want her working and there are other people who are not working and her daughter is sick. Reporter is just worried her daughter is going to pass away. Patient is not laying on her butt, she is working and it is killing her. Reporter doesn't know why her daughter can't see a cancer doctor to see if it's cancer. The reporter's mom died at 65 years old from stomach cancer and the reporter's sister died at 50 and now the reporter herself is dying. Inquired for when all of these side effects began for patient and reporter states that it couldn't have even been 2 days after she had it. Patient face and lips were swollen and told the reporter that she got the vaccine. Patient had said that her chest was really cold and the reporter knows that means it is not getting oxygen in there. Patient was never on anything except antidepressants, she has always been on that. The doctor doesn't usually give patient pain pills but the doctor started giving them after the fact for her back. She has a back brace that she has to wear on her back and that's where her lungs are. Patient never smoked a cigarette in her life and is sicker than her mom who has cancer. Patient has to go to the hospital and then they send her home. Outcome of the event face being swollen was recovered after one week, back pain was not recovered, unknown for the rest events.  The lot number for BNT162b2 was not provided and will be requested during follow up.
