I felt like dizziness; I was getting a little feverish; I felt like my balance was off and my equilibrium was off; I was in the bedroom and for a brief, like moment, I felt like wheezing, like the room was spinning.; I was dehydrated; I felt like wheezing like the room was spinning and I kind of felt like; 3 cases have it and it was only a minute each, it was enough to scared the shit out of me.; This is a spontaneous report from a contactable consumer (patient). A 50-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Formulation: Solution for injection, Lot number: EW1087, Expiration date: Unknown), via an unspecified route of administration on 06Jun2021 (50-year-old at vaccination) as a Dose 1, single for COVID-19 immunization. The patient's medical history included Covid infection more than a year ago in March and moderate high blood pressure, that's not treated right now, that's all. The patient's concomitant medications were reported as none. The patient stated that she had COVID a year ago, last March and she received one Pfizer vaccine in 06Jun2021 and she said that she didn't had any side effect except, she was getting a little feverish but she felt like dizziness, like she came out of the bathroom. She was in the bedroom and for a brief, like, moment, she felt like wheezing like the room was spinning and she kind of felt like, Oh, My God. Let her hang on side of bed, right, so she doesn't know. She was schedule to get her second vaccine tomorrow. She really would like to get it, but she had COVID already, she does have antibodies. She does have T-cells and memory cells and then she had the vaccine first one, it acts like a booster if she had already and that's still going to give her protection against the delta variant right. It's not going to give her the 90 or 80 percent protection but, why had COVID immunity, you know and then she had the shot she meant she should have at least 80 percent right. Because previously, if she got dizzy, she had read report online. If people getting the Pfizer vaccine, they are becoming very dizzy for like after the second shot, they have the dizziness in the first shot and then the dizziness kind of went away after few days, off and on and that felt like her, she had it like, a day or two off and on but only like, 3 cases have it and it was only a minute each it was enough to scare her. She was not going to lie and because she never loosed her balance. She doesn't drink, like she was not an alcoholic. She was not on any of the medication. However, she does have moderate blood pressure, that's untreated so, she may be dehydrated. It was a very hot day, but she was just like so scared of getting the shot tomorrow it's feeling the same way but worse."  She stated that, she noticed dizziness like she knew an adverse reaction was dizziness in her thing, it's considered an adverse reaction, dizziness so she wanted to make sure that she doesn't get it again and then safety unit would guarantee her that, she won't get it even worse because it would be life changer. She stated that she doesn't think she would die or hospitalized after having a vaccine and had Covid, it would be a fight but, it would not be a fight felt like, it was before". She stated that she felt like she just got off the boat, she felt little like wheezing, it didn't happen, when she was at target, it didn't happen for few hours after, when she got home and she just felt like, she sat down and got up too quick and the room kind of spin a little but then it stopped it wasn't constant. It was more like, she got off the boat and felt like, this was not right, couldn't got her balance, she felt like her balance was off and her equilibrium was off. She stated that she doesn't felt doctor or anything. She did feel one moment, she did feel very strong, what the hell did to her body, she felt like, she was not herself and that time just exactly she doesn't want to feel tomorrow. She stated that it's fully improved but, it had for like 3 days like once or twice a day at random time and just totally random like she didn't even know what she was doing, and it just came like she just got off the boat. She stated that, it was just may be dehydration or hot that day, she doesn't know, and she was not really excited to take that chance again and feel the way. She did before especially feel worse. She stated does safety unit sheet work said adverse reactions and dizziness was one of them. She said if it was there, they said not to take second shot if she had dizziness. She was informed and requested to contact Pfizer medical information department. The outcome of the events was recovered on an unknown date in Jun2021.
