A 65-year-old female patient received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, formulation solution for injection; Batch/Lot Number: Unknown, Expiration date: Unknown) via intramuscular route of administration in Left Arm on 25Jun2021 as dose 1, single for COVID-19 immunization.Medical history included foot operation (surgery once on her foot) from an unknown date and unknown if ongoing.Concomitant medication included ibuprofen (ADVILGEL).In Jun2021, the patient experienced arrhythmias/ constant arrhythmia, would feel a little bit dizzy, couldn't quite catch a full breath/ not quite breathing deeply enough or getting enough oxygen, felt a heaviness in her chest, feels lightheaded, crabby, brain fog. On an unspecified date, patient experienced myocarditis, pericarditis, when she lays down to go to sleep and her heart starts going boom boom boom, not able to fall asleep very easily because her heart is beating like that, it energizes her and keeps her awake, the heart palpitations are worse when she lays down, chest pains, have a blister/boil on their leg.On 25Jun2021, patient had arm pain.On 26Jun2021, the patient felt kind of tired, just lethargic. The event arrhythmia lead to visit Physician Office. She had a surgery once on her foot where they had to cut her open and the expected time later, they went to take the stitches out and her skin hadn't even started to mend so they made a mistake. Caller stated this is a big shock to everybody even as she was saying that they need to make sure they look at her and not what they expect to happen to her, and they never listen to her until that happened one day and of course she's not in a proper place to have her skin opened up left open. Family history None, caller stated there's no heart arrhythmia issues in her family. Caller stated she didn't even know what it was until now. Caller stated literally until yesterday when she looked it up. Caller stated her doctor said it sounds like an arrhythmia so she looked it up and every single symptom was like check, check, all of them and what was really interesting to her was that this article specified as WEBMD, specified that its worse, the heart palpitations are worse when she lays down and it was very specific about where she feels the pressure and pain and it said in the middle of the chest, up where the heart is and right below it where the solar plexus is and she's thinking oh that makes sense, if it's her heart muscle that's swollen or the lining that's swollen and its sitting on her sternum then that makes sense, that area of the sternum has to do with her breast, her lungs too, taking an actual breath. Caller stated it doesn't feel like her lungs, it's her heart/chest area, that was interesting to her that its worse when she lays down and that's when she's trying to sleep, that' the nightmare of it. Caller stated she talked to her doctor and a couple of people and they suggested that she call Pfizer to ask these questions because Pfizer knows. Caller stated she knows it's a work in progress, but the doctors aren't on top of everything. Caller stated initially, the day after the vaccine, she felt arm pain, felt kind of tired and maybe not even sick just lethargic. Caller stated she wanted to nap a lot, which she did because she kind of didn't have a choice. Caller stated on 25Jun2021, caller stated her arm started hurting on that same day. Caller stated her being tired started the next day 26Jun2021 and is ongoing and persisting. Caller stated and she has more symptoms and now with the symptoms that have progressed to the arrhythmia. Caller stated along with tiredness, she would feel a little bit dizzy, there was one day she felt like she was going to faint, but she didn't. Caller stated she felt like she couldn't quite catch a full breath and then it was a week later. Caller stated it kept going, symptoms got worse, then she felt a heaviness in her chest, she felt like, she's still feeling it now, like she can't quite get enough breaths, her lungs don't bother her, just feels more like chest and solar plexus that area, just feels really heavy and so during the day she feels tired, like she's not quite breathing deeply enough or getting enough oxygen or something. Caller stated then at night when she lays down to go to sleep and she's tired, her heart starts going boom, boom and she goes what is that and that's been going on pretty much every night, what is it a couple of weeks now. Caller stated it happened last night, so she's not able to fall asleep very easily because her heart is beating like that, it energizes her and keeps her awake and that's where they are today. Caller stated it all started right after the vaccine. Call confirms all symptoms began in Jun2021. Caller stated for the vaccine, she has never had an arrhythmia in her life. Caller stated this is happening and so because she doesn't fit into the standard population that's getting these symptoms, she feels like her doctor just dismissed it because oh it must not be happening to her. Caller stated as she's talking, she feels lightheaded, dizzy, her chest is heavy, she's tired and she's a healthy person otherwise as far as exercise and diet and how she takes care of herself and so this is hard. Caller stated the only antidote she would add is that she does have a history since childhood to present of not being able to process medications very quickly and also, she has a very slow, her ability to heal things is very slow, but she heals, but she's kind of like the antidotal patient that people don't understand, they look at her and appear healthy. Caller stated so this is her, this is her life, and she was actually kind of nervous about getting the vaccine because she's like she wants to protect herself and it took her a really long time to decide if she should get it or not, she thought long and hard and she is the person in the 1 or 2%. Caller stated when everybody was trying to convince her to get the vaccine, they said most people don't have this, that and the other side effects and she is usually not in the most people category. Caller stated so now she's in a position where she is having a situation and she doesn't know what to do. Caller stated she doesn't know. Caller stated her common sense tells her first she needs to deal with what's happening and heal and then is it a good idea for her to get vaccine number two when she is still having these problems? Caller stated her common sense says no but she hasn't been able to get anything concrete, the nurse that just transferred her over didn't know she had to look it up. Caller stated she wants to talk to somebody that she can talk to. Caller stated she feels like she's falling through the cracks and that's not necessary. Caller stated she thought, alright, this is going to pass at some point then a week after that she started feeling more. Caller stated it's not a good loop, if the call handler doesn't know and Medical doesn't know then obviously nobody knows. Caller stated she has to figure out who then does she talk to? Caller stated pharmacists are going to go off what Pfizer knows, so it's all really stemming from what she doesn't know and that this is a work in progress and as Pfizer gets new information then Pfizer puts out new information. Caller stated her situation is registered with the CDC and with Pfizer as a side effect so yes this is a side effect then with that A) What's causing this side effect? B) Will she heal from this and will it work its way out? C) Is it safe for her to get another dose? D) What's the longest she can wait? Caller stated those are the kind of questions, relevant questions for her and she absolutely needs to get answers to them. Caller asking who does she talk to? Caller stated she needs to escalate, she's in a tier and nobody's able to answer. Caller stated they told her 6 weeks, but they didn't tell her if they could go beyond 6 weeks because she brought it up. Caller stated in country, they are actually recommending for Pfizer 12 weeks, isn't that odd? Caller stated their version of our head Dr. that they have a medical health whatever person figure head, and that lady is recommending 12 weeks and saying that there's all kinds of information saying that if Pfizer will actually have a better effect if people wait longer between doses whereas in country, we are getting them between 3 and 6 weeks and if people go longer, Pfizer is saying they can't guarantee that it's going to be effective. Caller stated its two contradictory pieces of information that doesn't make sense. Caller stated she doesn't want to hurt her heart anymore. Caller stated she doesn't want to hurt herself; she doesn't want to get Covid, the delta variant, but she's starting to feel frustrated and pissed off like she feels like she needs better information and she's not getting it from the source. Caller stated she also feels crabby, it's persisting. Patient stated I had a side effect after the first dose of the vaccine; she questioned If I should I get the second dose.
