The pharmacist reached for the wrong syringe, and she got 2 Pfizer booster shots. The patient has been getting Pfizer shots throughout. She is better now. The patient is shrinking, is about 5 foot 1. The reporter did not see her about the side effects. The patient had side effects the next day, they kicked in on Saturday. The patient got the 2nd dose booster Pfizer Covid 19 vaccine about noon. Pharmacist didn't give her any details about the 2nd dose she got, once he did it he had this horrible look on his face and said he thought he gave her another Pfizer Covid 19 booster in her other arm.  The mistake happened and he gave her the booster in one arm and instead of the flu shot in the other she got another booster. That night, 14Oct2022 she had a headache that was really extreme, and it scared her.  The next day, 15Oct2022 she had a fever, was achy all over and nauseous. Her temperature is normally 97.1, lower than it should be and she was 99. something. These lasted a full day and when she woke the next morning, 16Oct2022 they were gone. She knew it was side effects because when sick your symptoms gradually feel better and this just appeared and disappeared, it didn't fade. She woke up and they were gone with no remaining effects. Concomitant medications: does take medications for 2 minor autoimmune things. States the symptoms were clearly from the booster shot and declines to provide details regarding medications. She is overall healthy. She was seen by withheld because she was getting nervous about the fever and travelling on Monday. They took her temperature and did a general examination. Time the Vaccination Was Given: around noon. Anatomical Location of Administration of Pfizer vaccine considered as suspect got a dose in both arms. The patient didn't want any more shots and decided to wait to see what happened. He tried to mitigate their discomfort by saying not to worry because it was Pfizer dose is a more diluted dose of Moderna and to think of it as if she had gotten Moderna booster. That she shouldn't expect any bad effect as it is like the equivalent to Moderna's booster vaccine. Headache started same night 14Oct2022 and fever, was achy all over and nauseous started on 15Oct2022. The patient did not receive other vaccines within four weeks prior to COVID vaccine.
