A 15-years-old non pregnant female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE), dose 1 via an unspecified route of administration, administered in Arm Right on 15May2021 16:00 (Batch/Lot Number: EW0182) as single dose for COVID-19 immunisation.

Prior to vaccination, the patient was not diagnosed with COVID-19. Since the vaccination, the patient has not been tested for COVID-19. The patient previously received Amoxicillin, Azithromicin, Cefdinir, Gardasil(Pf) and had allergy. The patient had Nausea that does not go away with Gardasil. She also received HPV vaccine previously and experienced nausea and the dizziness for a month.

The patient had the COVID Pfizer Vaccine on 15May2021 and as soon as she had her first dose she started to feel nausea and dizziness and from there 5 days later she had, she felt a terrible headache, 'this heaviness' (not clarified), headache, dizziness, palpitation. The reporter took her to the emergency room, they did all the test and they didn't really see anything in the results. From there she cannot stop to have nausea and dizziness and clogged throat so the reporter had to give allergy medication to her every day. She did have, she never had an allergic reaction to any vaccine but the HPV vaccine (captured as unspecified vaccine in tab) what was similar to what she is experiencing now. She had nausea and the dizziness for a month that she couldn't stay in school and she has this nausea and dizziness and clogged throat she has to run for this allergy medication what normally she never needed. So, she doesn't want to take this second dose and the reporter was wondering if it is Pfizer because she was just like (Height), a (Weight) pounds if because the reporter understand the vaccine is one for everybody, isn't this strong for a kid with that height that weight, that you do not needed the second dose. The patient could not she said she will not because she goes to school and she feel the nausea and dizziness and so. The reporter would like to report it because it maybe Pfizer's that she was thinking that 1 dose would be enough for kids. When asked about the start of experiencing adverse events, the reported stated that "Well the nausea and dizziness, she was a little bit not sure about like headache right after like her we stayed there like half hours because the doctor said to stay there because she has her reaction to which but then we just the reporter felt the nausea and everything was so bright you know, the reporter had the same effect but her went away and the patient after we received she was, the whole day but not too bad, 5 days after then she but she was already with this nausea, dizziness and 5 days after she got the palpitation, bad headache, nausea, dizziness and then I took her to the emergency room." Reporter stated, "No they have improved, the only thing now left is every day she has this nausea, dizziness and then she said about dizziness and then nausea and then clogged throat and then the reporter gave her the 'allergic pill I gave that, to this allergy' (not clarified further) really she gave only 1 tablet a day."
