An 85-year-old female patient received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, batch/lot number: unknown, expiry date: 30Aug2021) (age at the time of vaccination was 85 years old) via an unspecified route of administration, administered in arm left on 04May2021 as DOSE 1, SINGLE for COVID-19 immunization. The patient's medical history included allergies, allergies to sulfur and iron and was allergic to many things and would like to know if any of those things are in the vaccine. Has had the pneumonia shot and the flu shot and has never gotten sick. Concomitant medications included Losartan for blood pressure, Levothyroxine (has been taking probably since in her late 50's) for thyroid and vitamin D. Caller mentioned that she used to take one of those pills for bones and now just takes D. She cannot get too much calcium. She can build up calcium since she loves dairy foods. She is otherwise doing real well and her pressure was good. Was blood tested last month was ok just needed a little vitamin D. No prior vaccinations (within 4 weeks), last vaccine in the fall was flu and pneumonia, September and October at the doctor's office. On 04May2021, arm was initially sore but since then it feels like it's affecting her whole side, form her left arm down to her legs and even her ankles. Also states it's in her stomach muscles. Caller was feeling dizzy in May2021. Caller would like to know if she can get the second dose of the vaccine. Caller was also allergic to many things and would like to know if any of those things are in the vaccine. She was 85 and this was her first time. She got hers two days ago and had a reaction and does not know if it was normal. She had it in her left arm. It seems like it affected her whole left side. She is a little dizzy. Her arm was really really sore. The next day her arm was not sore but the rest of her body was. It went down her arm, legs and down to the ankles, even in her stomach muscle a little. The patient was wondering if she should not get the second one. She wears her mask every where she goes. She was really concerned. She had a good check up on the 29Apr2021 of last month and everything was good. The patient had lots of vaccines but never experienced this anything like this one. Is not going to take the second one. This really scared her. Never had a reaction to any other vaccine in her whole life except for a little sore in the arm. It kind of scared her. When she was at the grocery store with her debit card, she almost forgot to push the entry button. The patient was allergic to lots of things, like sulfur and things. Is wondering if there is something in them. There really has not been any proven literature that it prevents the virus itself. Is there maybe something in the shot. Left arm pain: Got the shot in the morning about 10:30. Was talking to her granddaughter after 7, it was afterwards that her arm got really sore and she could hardly sleep on 04May2021. The next morning the arm pain was gone. The next day, her whole left side started hurting. It was her stomach muscles, legs, ankles and hands on the left side. It started the evening she got the shot. It went probably until the next day. When she got up the next day, it shot up her blood pressure a little bit on 05May2021. She takes 2 pills, a thyroid pill and a blood pressure pill and a vitamin. Wasn't told to stop nothing and took her regular meds. Today she seems like really tired on 06May2021. Her hand hurts and itches in the corner. Thinks she had a bad reaction. Every once in a while, she feels it in her hands and leg. On 05May2021, her hand was itching, in the thumb, above the thumb. Is also in the lower part of her spine. The itching started really late yesterday. She took a shower and then the soreness in her arm went completely away. It comes and goes but not like the first time. It is better now. Still feels itchy. Is very allergic to sulfur and iron. Could have been something she was allergic to. The itching comes and goes, especially in her hands and lower spine. She was a little confused in May2021. She almost forgot to press the button. The patient did not receive any treatment for the events extremity, pain, feeling dizzy, pruritus, little confused, fatigue and insomnia. Thought maybe if she should take the second one? Is afraid and lives alone. Her grand daughter is a nurse practitioner and has a button and a machine she can press. She is mainly concerned about how she felt. Does not think she is going to take the second one. No one even told her to get it. Otherwise, feels pretty good, can still drive and feels safe. This was a reaction in her opinion. Reaction has still not gone away. The outcome of the events pain in extremity, pain and hypertension was recovered in May2021. The outcome of the event feeling dizzy, pruritus, little confused was not recovered/not resolved. The outcome of the event fatigue, insomnia was unknown.   No follow-up attempts are needed. Information about lot/batch number cannot be obtained.
