Additional information: The patient who received her first dose on 06Jan2022. The patient developed rash on both elbows and on one arm. The patient experienced hives on her elbows going up her arm. The caller confirmed her daughter was given a vaccine record card but the card was with her daughter who was at work. The caller stated her daughter was at work and telling her the hives started on her elbow and was starting to move up her arm. When probed to determine the outcome, the caller stated she was texted her daughter about it now. Unable to confirm if the hives were improving, persisting or worsening. At the vaccine facility, the caller signed the paper saying okay it was fine for them to give her daughter the vaccine although she probably didn't have to do that, the facility wanted the caller to sign it. The caller was hoping and praying the hives were nothing serious where it has to be an ER visit. If so, the patient's father is really going to flip his lid. The caller knows if it starts getting worse it's going to require an ER visit and it's not going to be a good day. The patient not received any other vaccines within four weeks prior to the first administration. The caller stated that her daughter would swell everywhere but her throat and tongue. It was initially thought her daughter was allergic to every antibiotic but it only happened before her daughter developed a virus. Her daughter outgrew it. The caller clarified further it was determined it didn't have anything to do with antibiotics. Her daughter was not allergic to anything now- no food, no dyes. It was initially thought her daughter was allergic to everything but air including dyes, antibiotics, but then it was determined her daughter couldn't be allergic to antibiotics. It was finally realized that her daughter would break out right before she started getting sick. It was like her daughter's body was telling her that she was getting ready to be sick. She states her daughter would develop bumps raised above her skin, like great big welts and her daughter would swell everywhere except her throat and tongue.
