She reported that whenever they got it, her daughter and her both got it, she wound up having a big red rash that was a pretty good size, it hurt really bad, she got a knot, and she got a fever of 101.6 with it. Her Daughter's arm was bruised for weeks after and it looked yellow, and it got kind of itchy. If they had to get it again, they wouldn't, they were not happy with it. Both of their jobs are in the public all of the time, so they decided to get the vaccine. She was glad that she didn't get the flu shot with it at the same time. Caller stated that with a Flu shot, she just had stiffness and soreness and then it's done but this she had never experienced anything like it in her life after a vaccine. NDC, Lot, Expiration: She doesn't recall any of the dates nor the dates she got it. She couldn't tell the dates, but this happened over a couple of months ago when someone said that she should say something. Caller got it at [withheld]. Her rash recovered with lasting effects because every once in a while, it felt dry and itchy still. She was aware of where she got the shot. She also missed a day of work because of it. Caller stated that they have gotten all of the vaccines and the boosters, and they just went ahead and got this Booster because they both work at public places and Covid was still around, and she had a teenage grandson that goes to school so they are exposed to Covid. The caller declined to complete a Full Report for her daughter. The caller stated her daughter was doing alright. She reported her daughter had bruising and it stayed yellow. She doesn't know if her daughter has still gotten rid of it. She doesn't know if it was because of the way it was given or what. They have never experienced anything like this. It was such a negative experience. The caller stated that she doesn't know what components it had in it but another coworker has an allergy to sulfur and her daughter was allergic to latex and they have to be careful of what they get. She doesn't have any of those issues, so she was surprised she had such a bad experience. She was worse than her daughter. They got the shots on a Friday, and she was supposed to work on Saturday night, and she couldn't go. She felt awful and had a fever and her daughter was able to go to work on Sunday.
