A 58-years-old female patient received first dose of bnt162b2 (PFIZER-BIONTECH OVID-19 MRNA VACCINE, Solution for injection), via an unspecified route of administration on 18May2021 (Batch/Lot Number: EW0185; Expiration Date: Aug2021) as 1st dose, single dose for covid-19 immunization. Medical history included allergic to almost every antibiotic known to man (as well as her daughter and family), like erythromycin. Patient stated doxycycline and prednisone were the only two medications she had not had a reaction to. There were no concomitant medications. The patient had the shot on Tuesday (18May2021) and she didn't get second till, on Friday night it was almost she had lump in her throat, now she don't know if that a common thing if she should go back and get the second shot. Patient did not believe that she was the root of what was happened, but it was a reaction that was quite relate. Patient stated that her doctor told her that she should, but she said that she was afraid, that as it was happened with the first time it's going to happen worse again the second time. Patient stated that 3-4 days after her first vaccine she started having symptoms and main concern was that she felt like she had a big air bubble in her chest (at one point she said this started Thursday night and then later sounded like she said it began Friday night). On 21May201 (Friday), patient had the fatigue hit before work which caused her to start reading stuff about myocarditis and Friday around 3:30 something she didn't feel right and Friday night it started and it depended on the way she sat, it was really really bad, and she tried to calm down and relax and on the same day patient took Advil and Pepto-Bismol. On unspecified date of May2021 (about 5 days later) felt like their throat was closing, had a headache and didn't feel well after first dose as well. On unspecified date of May2021, patient functioned day to day but had a headache and upset stomach for a couple hours, fatigue for two weeks, a lot of phlegm in her throat and had to keep swallowing. Patient stated she still worked out every day and did cardio. Patient was supposed to get the second dose on Tuesday but she was also seeing her doctor that day, so she waited to see what she said. The doctor originally thought her D3 levels could have been very very low because she has been researching the vaccine and said that people with low D3 levels had reactions. But her doctor also said no one has died from the vaccine and she had read people had died so she knows that was a lie. The doctor does not suspect that her experience was myocarditis. Patient asked if these symptoms were normal and will the reaction after the second dose be worse. The patient went to her doctor, she had blood work done on 01Jun2021, she thought maybe it was due to may be something else was going on in her blood she said her blood work was perfect specimen of health and told her to go for the second shot. The patient was also tested for the COVID and antibodies and both were negative. Patient need to speak to a pharmacist or one was a doctor would be able to help her because it was really based on the reaction that patient had to the vaccine. The outcome of all the events were unknown.
