A 68-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Batch/lot number: EL9265), via an unspecified route of administration from 29Jan2021 14:45 (2:45 PM) at single dose on right arm (as she was left handed) for COVID-19 immunization.  Medical history included COVID (recovered) on an unspecified date. There were no concomitant medications. No additional vaccines administered on same date of Pfizer suspect. Patient previously got her flu and shingles shot at the end of "October". Patient took the vaccine last Friday (29Jan2021) at the age of 68 years old (reported as "68 and a half"). She does not know if that makes a "different" but her right arm felt like it was going to fall off it hurt so bad, on a scale of 1-10 it was about a 20. It was really tender she put a heating pad on it, she has been sleeping on the heating pad and it was mild now. It was only about a 3 now and it has come down, but it hurt like the dickens. Also she has ran a temperature and that finally broke but the highest was 102.4. Patient has slept around the clock and she has not been out of bed but like 30 minutes out of the last 24 hours (hrs) just to go the potty or drink something. Patient stated "almost gave up holding it was so long". She has been so weak she has not been out of bed hardly. Patient said that she has eaten since, "lets see Saturday night, Sunday, Monday". Patient has not eaten since Saturday night (30Jan2021) or gotten out of bed. She has not eaten anything. Patient has had COVID and recovered so she did not want to catch that again. She confirmed that she had COVID prior to received the vaccine. She called her primary care and she has a viral phone call tomorrow or visual phone call, whatever its called, she was trying to get over this mess, she feels warm, she was not registering a temperature right now but she had a cold sweat or something right now (01Feb2021). Patient has a call with him tomorrow so he will know about this incase Pfizer calls. Patient stated that she knows with a normal vaccine she might have an ache or something but this one hurt bad, maybe they pushed it in too hard or something she does not know. When asked for vaccination facility type, the patient answered that they had a vaccine clinic they had set up there in a conference room, they had an elaborate set up, go through certain places and there were several steps. Vaccine was not administered at facility (reported as "No hospital"). Patient further reported that her arm on 29Jan2021 (Friday evening) was tender. Patient lives by herself, she came home and does not know if she event ate. All she knows was she was real tired that Friday evening, it was tender and it got worse. Events did not require emergency room and physician room visit, reported as "Not to date but tomorrow she does not know if he will have her come in unless she spikes another fever or if he will do anything she may just ride it out". When asked for adverse events prior vaccinations, the patient answered "no none that she can remember. Sometimes she will have a sore arm that is why she gets it in the right arm because she is left handed thinkin her dominant hand will not have any problems but this one hurt really bad. Have they had many calls where this is really effecting arms really bad?". Patient also reported that her sister had the shot the same day and her arm was a little sore but that was all, she does not have NDC lot expiration for her sisters dose of the vaccine. She went to a different facility in a different location. Outcome of "her right arm felt like it was going to fall off it hurt so bad" was recovering, while for other events was unknown.
