she would faint; sick and she thought that she was going to die; hit her head and injured her head; could of fell and hit her head on the floor that is hard; dizzy; didn't feel good / horrible feeling; weak; diarrhea; feeling of vomiting; arm pain; feeling unwell; severe allergic reaction; This is a spontaneous report from a contactable consumer (patient).   A female patient of an unspecified age received bnt162b2 (PFIZER-BIONTECH COVID-19 MRNA VACCINE), dose 1 via an unspecified route of administration on an unspecified date (Batch/Lot number was not reported) as 1ST DOSE, SINGLE DOSE for covid-19 immunisation.  The patient's medical history and concomitant medications was not reported. Patient says that on Monday she went to go get the COVID vaccine and then Tuesday she called Pfizer and told them that she had a severe reaction and she told them all of her symptoms. But then on Wednesday, yesterday, she went to work and she was fine and then all of a sudden she was in the gallery, she is a security officer, and everything went dark and she was getting dizzy. It was a horrible feeling. She called her supervisor who came and the Patient said that she didn't feel good and she thought that she would faint. Her supervisor told her to sit down and put her head down so she did and that had calmed her down but she was still so weak. She said that she has got to go home and they asked her if she needed an ambulance and she said no and she walked to her car. She probably should of asked for someone to go with her for her to lean on but she guesses that she was so involved with what was going on that she didn't tell them that she needed that help. That is the reaction that she got yesterday so she called right away to her provider and told them what happened and she talked to the registered nurse there who said that the Patient didn't need to go to work today either because the side effects usually last 3 days. She also informed the Patient that if she is still feeling like this the next day, Friday, then she needs to go to the emergency hospital. The Patient mentioned that someone else called her yesterday but she doesn't remember the phone call because she was so out of it. So she went through all of that. After her COVID vaccine, she had diarrhea as soon as she got home 2 hours later. She has also had the feeling of vomiting the day before yesterday and she had arm pain, she was feeling unwell and she had that severe allergic reaction. She just wanted to let Pfizer know all of this because the COVID vaccine got her sick and she thought that she was going to die. She could of fell and hit her head on the floor that is hard and something could of happened but God took care of her and put an angel there and she had reacted so fast but she could of hit the floor. She wanted Pfizer to know that because she needs money and she shouldn't of even gotten the COVID vaccine. Now she has got to get the second one since she had the first and she is scared to get the second one thinking that the same thing may happen. Also, as she was reading about it and this vaccine doesn't even help you, you can still have the virus from what she is reading and this vaccine is also unapproved. She says that she think that she has already spoke to someone about this, but as she was reading it she saw that really it is saying that it is an unapproved vaccine. She has to go Monday and Tuesday to her doctor, a specialist, and tell them what she went though which was horrible. She did have a severe reaction to this because she got so sick and she could of hit her head and injured her head but God put an angel there. She said she felt like she was fainting and that is why she called her supervisor right away. She said that when she woke up she said she wasn't going to come in to work today because the registered nurse said to go home and relax because it can take 3 days for the side effects to go away. She has been okay for right now. She has had a lot of fluids to drink since the nurse told her to do that and she has chicken noodles because she feels so weak. She is just concerned about the second one, it scares her. Why are they giving this Pfizer COVID vaccine. Is that the only one in the world. She is just curious. Patient declined to complete a full follow up report and said that she just wanted to let Pfizer know what she went though and if she would of gotten hurt then who knows what, but thank God nothing happened and an angel was there protecting her. Right now she just feels so weak. The outcome of event weak was not recovered. The outcome of other events was unknown.  Information on the batch/Lot number has been requested.
