A 71-year-old female patient received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE; lot number: E18982), on 21Jan2021 (at the age of 71-year-old) at single dose for COVID-19 immunisation. The patient reported that based on her history of reactions to medications, the nurses giving injections "decided 0.2ml instead of 0.3ml", which is what they gave, so she got 0.2 that is two-third of the shot. The 2nd shot was for 8'oclock on 11Feb2021. She is very sensitive to shots, vaccines, and to all medications and injections and things like that. She has sensitives thanks to two concussions she had in her life. She never was before that she had two concussions. Second one had a crazy man hit her after that just noticed that just have reactions not adverse or dying but definitely take rest of everything. So she take less of a shot, like a dental shot or cortisone shot, which she had taken in the past. If she has dental shot she cannot take Novocain, had to take Carbocaine or Marcaine and they give her half. Also she had been taking cortisone shot for shoulder for rotator cuff injury. They also have to give her less. Or flu shot: she takes half one week and come back for the other half the next week. Just have reactions. She told to when arrive for medication and did have one anaphylactic reaction but that was to cat skin dye, was told to this two nurses who was administering the vaccine and said to them she was really afraid to take. It is just too much for her. She knows her body. She is sure have reaction but is really afraid and don't know what is the first one will do to her. They just did two nurses and she decided that she will be taking  0.2 instead of 0.3ml which is what they gave. She got 0.2 so that two third of the shot and waited the half an hour, a nurse watched her card and 7 other cards. She did not have the anaphylactic reaction.  She went home. Her arm hurt and started to get little tired. The events started the day that she got the shot. Like about 3 or 4 hours later. It is just few hours later she couldn't watch TV so went to laid down and an hour later she woke-up. She walked to her kitchen and blood drained from her head, she just knew she was going to pass out. Her stomach suddenly did not feel well. She tried to get back her bed but she was round up and as far as the bathroom. She got very nauseous, she laid down on bathroom floor. She thought she was sick but didn't round up having to use toilet of few times. Although while she was feeling she would faint. She was very hot and so hot. While lie down, she couldn't even pulling off her pajamas. So when she got cold so she was pulling a towel down and stop and she laid to for two hours, she finally got to her bed. It was a terrible experience. Next day she drank water and had potatoes prepared and went up eating back to later baked potatoes. Next day luckily she did not have repeat of the nausea. She didn't have that anymore of. She did have abdominal issue just not diarrhea or anything but just not feeling well, feeling gassy, so uneasy. This all lasted, that part lasted for 7 days. What concerned her was especially beside first day it was few days she got off again. She was just feel blood drain but not this first time she laid on floor. She couldn't sit on chair to watch TV for about 3 days. She mostly laid on bed but she would get very hot and then very cold during the day. She would get very fast heart beat not continue but really fast like heart was pounding her chest. She felt like someone has their hand inside her body squeezing her chest. She got afraid but didn't want to go hospital. She didn't think she was sick enough. She was concerned. So that was happened and this last was for about 7 days. Then the squeezing of chest part went away. She doesn't want to wind-up on the floor feeling that sick again, she felt so sick it felt like food poisoning. After that, it was just being very hot, then being cold, the fast heart rate, every muscle hurting. Those were the main things that continued for a week. And digestive disorders. It all lasted for about 13 days. She was concerned she had a very fast heart rate intermediately for many days, for about a week. And that's considered an adverse reaction and also she was getting waves of feeling like she would pass out, everything would drain from her head. She experienced stomach ache, feeling hot then cold. She wants to do precautions before taking the second dose on 11Feb2021. She did take may be 3 days later two Tylenol but didn't take anything (clarification requested). She didn't even take vitamins during that time. She was afraid to take anything so she did not. At the same time also there was pain in her body in every muscles, fingers, hands, calves, feet, back, neck, everything. Her stomach abdomen was just tight. She was concerned that last for few days. In last few days she started feel herself and now she is going again tomorrow. So that how she reacted. She doesn't know how much of this shot she told them she could tolerate because everybody is saying second shot will give you more reactions. All she can take this more than that because that was lot. She wants to be herself, don't want laying on floor, don't want to have 105 temperature or anything. The patient was asking if she should take another 0.2ml another two-third of the shot. She just asked them for half that is 0.15 would that be a big difference. She needed to know by 8 o'clock tomorrow. I might be in a queue to get it. She stated: 'So, that's my concern. I'm all alone, I'm a senior, I have no family. I lost my mother to covid. I know I need this vaccine, but I just, I cant get that sick and I'm so afraid I'll wind up with a 105 something, fainting away and no one knowing'. She was asking if reactions after the 2nd dose are worse than the 1st dose, if she didn't have anaphylaxis after 1st one, she shouldn't have it a 2nd time, right. She said, "1st half of flu shot, I get sick, then the 2nd half nothing". She also asked if she can take medications after the vaccine, like Tylenol, or irritable bowel syndrome (IBS) medication she takes as needed. The events resolved, but the patient reported it took her like 13 days before she felt better.
