A 24-year-old female patient received first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, solution for injection, Lot Number: FA7484) via an unspecified route of administration at left arm on 27Jul2021 19:00 (at the age of 24-year-old) as dose 1, single for COVID-19 immunisation. Medical history included high functioning autism from 2000 and ongoing, obsessive-compulsive disorder from 2011 and ongoing, hormonal migraines, underlying anxiety disorder, ovarian cyst from 2016. The patient's concomitant medications were not reported. The patient previously took mmr vaccin and received MMR vaccine when she was 3 years old, if she had an adverse reaction, she was unaware of it. The patient experienced headache on 27Jul2021, anxiety, heart palpitations, bit of shortness of breath/difficulty breathing, on and off, mostly when she first wakes up, seems to be the worst, nauseated, had a difficult time sleeping, chills, she got some shakiness on and off/she is so shaky her teeth are chattering, heart was beating fast, has been feeling a choking sensation, left arm a little bit sore, coughing a little bit, developing food sensitives, difficulty eating breakfast on an unspecified date in Jul2021. The clinical course was as follows: Patient had the 1st dose of the Pfizer COVID19 vaccine last 27Jul2021 and experienced some of the side effects of the vaccine and she reported having anxiety, palpitations, bit of shortness of breath, nauseated, difficult in sleeping, chills, headache but gone away. What she was concerned the most was the shortness of breath and palpitations that usually occurs upon waking up. She was having difficulty in breathing especially without a fan and needs to go outside to have some air. She wants to know the urgency of her situation if she needs to be seen by a doctor right away. She further stated that Myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the lining outside the heart) have occurred in some people who have received the Pfizer-BioNTech COVID-19 Vaccine. In most of these people, symptoms began within a few days following receipt of the second dose of the Pfizer-BioNTech COVID-19 Vaccine. The chance of having this occur was very low. You should seek medical attention right away if you have any of the following symptoms after receiving the Pfizer-BioNTech COVID-19 Vaccine: Chest pain, Shortness of breath, Feelings of having a fast-beating, fluttering, or pounding heart. She further reports she was never diagnosed with hormonal migraines and she remembers she didn't make a connection that it was hormonal until later on, maybe some of symptoms of this vaccine with an underlying anxiety disorder could be the reason she was having this experience. Patient on the line stating she was having side effects from the Pfizer Covid 19 Vaccine after her first dose such as anxiety, heart palpitations, etc and she has had difficulty breathing, on and off, mostly when she first wakes up, seems to be the worst. She further stated that she can't really, her parents are anti-vax and they would be really mad if they found out about her getting it. She just received the vaccine a few days ago. Patient states this was her first dose and calling mainly because these symptoms she was having, she needs to know if this was an emergency, she needs to see somebody or she can wait and see her primary care doctor. Does she need to see a doctor before she gets the second dose. She further stated that she was vaxing to begin with. Her parents are anti-vax and she was hesitant at the beginning but this one was the safest one to receive, she heard recently about Guillain-Barre in Johnson and Johnson and went with this one thinking this one would have less of side effects, this one was likely the safest, it's authorized for 12 and up, so if they let kids receive it, it has to be pretty safe. She needs a vaccine for the school she was transferring to that's close to her job, they are transitioning to in person work, she works at a tutoring center, will do in-person training and also because of the delta variant. Her parents are afraid of the vaccine. She told her mom she was going for a walk and got it also she can't do certain stuff without the vaccine, she can't get into certain clubs or concerts, she can't get on a plane so there was several reasons why she needed to get this done. This could be an indicator of heart troubles, some of these symptoms are heart troubles or anxiety that's why she wanted to talk to Pfizer because she doesn't know. She got her first dose on 27Jul2021 around 7PM, she had anxiety leading up to the shot, she was trying to get transportation to get there. The anxiety sort of calmed down a little bit, she was told to take deep breaths and she was actually a little bit calmer immediately after getting the shot, she didn't get hives or anything like that. She didn't get dizzy or faint after 15 minutes then she called a rideshare provider, she drank a full electrolyte drink. She got into a rideshare vehicle to get home and she was really anxious to get home, she was walking and still kind of anxious and she laid down and stayed up until like 5 am and she got more heart palpitations than anything she has ever experienced before, it felt like she was getting short of breath, this was after when she was laying down when she got home. She was up until 5 am, then around 2 am, she got nausea, had a difficult time sleeping and she got some shakiness on and off and chills and she remembers she was on the phone with her boyfriend and she finally fell asleep at 5 am, her heart palpitations stopped at 3 am then the next day she had heart palpitations upon waking up the next day and she remembers experiencing anxiety because of this and she was still feeling nauseous yesterday and had some shortness of breath, she had a headache too, she had a headache immediately after getting the shot as well. By this time yesterday, she was developing food sensitivities, she's been trying to drink tea, ginger, that help with nausea and whenever she gets these episodes of heart palpitations it comes with shortness of breath and she has to go by a window. Yesterday morning she actually spoke to someone who worked at the hospital and they said it was anxiety and they said that she needs to take some deep breaths and continue taking tea and she did that and then she calmed down and she was pretty relaxed last night and she had a headache still then she went to sleep around 12 am or 1 am and then she thought it would be over with, and again when she woke up her heart was beating fast, she had heart palpitations and now she has been feeling a choking sensation, not gasping for air, just feel like its harder to breath without a fan or being without being by a window. She's also had difficulty eating breakfast, still has nausea, her left arm has been sore, the soreness is going away today, and she was just coughing a little bit, maybe twice, she had very brief coughing, she gets so shaky, she does get chills but only for about 30 seconds, she is so shaky her teeth are chattering. She has woken up every morning to heart palpitations and that didn't happen before she got the vaccine. Caller states it was something similar with a headache, it went away later in the day but right now she still has anxiety and she was still using a fan and stuff, she still has some symptoms right now because she woke up not too long ago, she had to work at 9, seems like waking up was the trigger. She reports everything else, she was still having it. She reports towards the end of the night, she was a little better. When she first wakes up she gets these symptoms, she doesn't know how long it was going to last, it was only been a few days she had had this. She doesn't know how long these will last for and that's what is scary. She was also having difficulty eating, she doesn't know if it's an anxiety attack symptom or a heart attack. She has never had anything this bad until after she received the vaccine, it seems worse. Patient confirms all other symptoms besides left arm being a little bit sore and headache, are persisting. She further stated that no because last time she was in the ER it was 2016 and she had an ovarian cyst. The main thing was she doesn't know what the urgency was, she doesn't know how soon she needs to see a doctor for this. Does the call handler know how urgent this was, She also has difficulty with certain foods, if she eats too many avocados or bananas she will get a migraine. The patient underwent lab tests and procedures which included heart rate increased: increased on an unspecified date in Jul2021. Patient did not visit emergency room and physician office for the events. Outcome of event headache was recovered on an unspecified date in 2021 and left arm a little bit sore was recovering remaining events was not recovered.  Follow-up attempts are completed. No further information is expected.
