Clinical Information:  Patient went to get lab work on 13Apr2022 and all her levels were perfect and her thyroid was okay. Cholesterol was a tad off and sugar was a tad off, but not a lot. Took the booster dose and by Jun2022 she was feeling bad, shaking, thought Patient had Parkinson. It was going to be her bday in Jul, and she was feeling like crud. Couldn't walk, had to have a friend help her. Made an appointment with her doctor and she ran a bunch of tests in Jul2022 and found her thyroid was way off. Her TSH wasn't even reading it was so low. Didn't understand what was causing that. Three months ago, her levels were fine. Took all these tests and has been seeing endocrinoglist for about a month and endocrinoglist diagnosed her with graves disease. Cant figure out how she got it because everything was good in April. Takes methimazole now and is feeling better. TSH is still off the charts at 0.005 and some of her levels are coming around a little bit now, but still the TSH wasn't even at 1. Calling because she was nervous to take the Covid booster shot with the medication she is one now. Wanted to make sure there weren't going to be any side effects or reactions because of the methimazole she is on. She has no idea that thyroid issues could be a side effect of the vaccine. She has had a total of 4 vaccines now. Doctor was floored. Thought she had Parkinson. She was going to be 66 and other than car accidents, has been pretty healthy up until this happened. Height: Caller was 5ft 2inches. She's shrunk, but she doesn't know what from. Because, with graves disease her heart is racing very fast and her heart rate was 142-143 when she went to the doctor. The methimazole has bought the heart rate down though. It effects her bones and calcium and everything and her liver. Keeping a close eye on that. She was shocked to hear that she has shrunk. Before she knows it, they'll have to scrape her little body off the ground. She is the same height now that person was. Weight: She has lost 20-30 lbs. She is losing her hair and going crazy. Didn't realize that little butter-fly organ could mess up her whole life. In Jun2022, she started to feel really bad. Doesn't know exactly the date. Called to make an appointment to see (name), the nurse practitioner. Thought she was starting with Parkinson's be-cause her body was shaking, she was having panic attacks, everything worried her, her hair was affected, she would get very hot. It just throws her whole body off tilt. Nurse practitioner looked at her levels and saw it was the thyroid. Prior to this, she had had a little granular thyroid because she had got-ten her thyroid checked because her throat was hurting. Everything was okay with her thyroid then and her levels were great. Never would've thought that it could've been the vaccine. Now, she is leery to get the booster shot tomorrow. Doesn't think its safe for her to take the next booster dose.She wasn't even putting the whole thing together with the vaccine and the Grave's disease.Just takes a Vitamin D supplement. Prior to this, she didn't take medications at all.Just has a reaction to sulfa and Bactrim medications.She was calling because she wanted to know if the composition of the vaccine would interact with the medication she is taking. She doesn't know if the methimazole and the ingredients in the bivalent booster is made out of would react somehow. She didn't know that the thyroid could have been a side effect of the vaccine. The agent said that it could be a side effect of the booster shot. Did have granular thyroid, but her levels have always been fine. Is that something Pfizer has been getting reports about with the thyroid symptoms and the Covid-19 vaccine.Prior Vaccinations (within 4 weeks) If applicable, list any other vaccinations within four weeks prior to the first administration date of the suspect vaccine(s): None. She is not a firm believer in vaccines and didn't even want to get her flu shot, but she did get the flu shot at the beginning of this month.AE require visit to: Emergency room: the nurse practitioner wanted to send her to the Emergency room because her heart rate was so high at 142-145.

That was way after she got her vaccines, it´s been a while. She took her last vaccine on 27May2022.
