spike on her blood pressure for the past 2 days reaching a maximum of 205/125; fever later on the evening and the whole next day reaching 100.1F; body aches; chills; wakes up in the evening with a cold sweat; face was flushing bright red and goes away after a while; This is a spontaneous report from a contactable consumer (patient). A 45-year-old female patient received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for Injection, Lot number: EW0182, Expiration date: Unknown), via an unspecified route on 02Jun2021 as a single dose for covid-19 immunization. Medical history included hypertension for which she has taken intracranial hypertension medication Diamox, 250mg, twice a day for over a year now to lower her blood pressure, tubal ligation in 2015 and since then she is on a low dose birth control because she was suffering from migraines in the past and was getting shots and then was taken off of that and put on hormonal continuous treatment. She now has no periods and doesn't suffer from migraines. Also, she has COVID back in Mar2021 and had a severe case. The patient concomitant medications were not reported. On 02Jun2021, patient experienced a fever later on the evening and the whole next day reaching 100.1F (03Jun2021), she complained about body aches and for the next 2 days up until today she experienced chills and wakes up in the evening with a cold sweat ("clothing are wet because of the sweat") and the chills are also experienced during daytime (ongoing), her face was flushing bright red and goes away after a while. She knows for a fact that this is not hormonal because she is on a low dose birth control pill since she had a tubal ligation in 2015. So, she knows it is not pre- menstrual. She has had a spike in her blood pressure within the last 2 days with the highest reached being 205/125 (ongoing). She said her main concern was with the hypertension and she figured that all of her other side effects were normal, but it made her nervous with her hypertension and how her blood pressure shot up so high because her medication keep her blood pressure normal and it has never gone above normal on this medication other than two days ago when she had the spike and it has been high since then. She has been trying to keep it down and her diastolic keeps going above 90 and her doctor wants her below that. She has been trying to get in touch with the neurologist who prescribed her that medication and he is usually very busy. She has been on her medication for intracranial hypertension for over a year now and confirmed that she wasn't started on it due to the side effects from the COVID vaccine. The patient underwent lab test and procedure which included body temperature reading of 100.1F on 03Jun2021 and blood pressure measurement of 205/125. Patient wanted to know if the adverse events that she experienced are included in the most commonly reported AEs after getting the Pfizer BioNTech Covid-19 Vaccine shot, how long the adverse events usually last after getting the first dose and if the side effects that she experienced after getting the first shot would be a contraindication in getting the 2nd dose of the vaccine. The clinical outcome of the event her blood pressure keeps going up down to today, she does not have a fever anymore, but she is still getting chills and she feels like she gets flushing in her cheeks throughout the nighttime but she is still going on with no fever. One night she may wake up with sweats and another night she wont, and outcome of body ache was unknown.
