I was brought to the hospital by the ambulance because my throat swelled up.; eyes are tired; My body is itchy and feel like crap; My body is itchy and feel like crap; she's allergic to the Covid 19 vaccine; I was wheezing within 10 minutes after receiving the first dose of the vaccine.; This is a spontaneous report from a contactable consumer (patient). This 51-year-old female patient received first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Formulation: Solution for injection, Lot/Batch number: ER8732 and expiry date: 31Jul2021) via an unspecified route of administration in left arm on 29Mar2021 at single dose for covid-19 immunisation. Medical history included Multiple sclerosis (from 1996 to ongoing), 2006-2007, it was because of an MS drug (Interferon (receiving 3 times a week)), it gave her mild cardiomyopathy. She just stopped taking another treatment for multiple sclerosis called Mavenclad. Mavenclad is a chemotherapy drug. She received her first dose in Oct2020, she took Mavenclad for 5 days. Then in Nov2020 she started taking the Mavenclad again for 5 days. She doesn't restart the Mavenclad again until Oct2021. She reports the Mavenclad takes the B and T cells out of her bone marrow. When she has the next dose of Mavenclad, the B and T cells will be depleted again and when the B and T cells come back they are "tricked" so they won't attack her body. Her hair fell out in clumps with the Mavenclad and her throat swelled too. She would really like a haircut to fix her hair. She premedicated prior to receiving the Mavenclad. She reports she was premedicated for 3 days prior and the day she received the Mavenclad, with Benadryl. Within 15 to 20 minutes of taking the Mavenclad she had a reaction. Concomitant medications included vitamin b12 (about a year) for vitamin b12 deficiency and vitamin d (10-15 years) with calcium for Vitamin D deficiency. On 29Mar2021 within 10 minutes after receiving first dose her throat swelled up. The next thing she knows is people are all around her, she's on a gurney and she's going to the hospital in an ambulance. She would say she's allergic to the Covid 19 vaccine. In the emergency department she had to have an IV with all kinds of medications. Yesterday in the emergency department the doctor wanted to give her an epi pen. She told the doctor she didn't want to have the epi pen. In her IV in the emergency department she received Solu-Medrol, Benadryl (as needed), and Famotidine (20mg twice a day 10 days). She was prescribed Prednisone 20mg tablets, take 3 tablets orally every day for 5 days. She also reports she is allergic to egg whites, not deathly allergic. She can eat a hardboiled egg but she has to take Benadryl because her throat will start to close up. She can eat scrambled eggs just fine because the eggs are cooked different. The emergency room was watching her because if she didn't improve, they were going to give her the epinephrine. She started to improve, and she was thankful. She was afraid something else could have happened to her and her husband was in the parking lot and wouldn't have known. She's not sure how many hours she spent in the emergency room. She was not admitted to the hospital; she was discharged from the emergency room. Now she's taking medication for the next 5-10 days. She's not shocked, with her history and her reactions to medications. She didn't really think an allergic reaction was going to happen because the Covid 19 vaccine is not a live vaccine or anything like that. She's not going to look online for allergic reaction information because her eyes are tired. She's been up since 1:30 AM because of all the steroids she's on. On 30Mar2021, her whole body is itchy. She's taking Benadryl and the Benadryl has helped. The itchy feeling is moving on to different parts of her body. She had the swine flu when it came out and it was hellacious. She feels like Covid is much worse and she she believes in science. She knows Covid 19 isn't made up. She's all for the Covid 19 vaccine. Give her the Covid 19 vaccine so she can move on. She reports everyone in her family got the vaccine, and they were all fine besides aches and pains. When probing for specific information regarding the caller's family members, she reports her daughter, who is in nursing school had the Covid 19 vaccine. After her daughter's first Covid 19 vaccine, she had a sore arm that night and she was really tired. The next day her daughter felt a little lightheaded and she felt like she had flu symptoms. She had some body aches. Then under her daughter's armpit where her lymph nodes are were swollen. By the third day her daughter felt better. She was totally fine. She thinks her daughter may have reported her experience online. The outcome of event eyes are tired and I was wheezing within 10 minutes after receiving the first dose of the vaccine was unknown, the outcome of event My body is itchy and feel like crap, My body is itchy and feel like crap and she's allergic to the Covid 19 vaccine was not recovered where the patient recovering from the event I was brought to the hospital by the ambulance because my throat swelled up.
