A 57-years-old female patient received second dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection; Batch/Lot number, UPC number, expiry date was reported as unknown) via an unspecified route of administration on an unknown date in Jun2021 (at the age of 57-years-old) in left arm as a single dose for covid-19 immunization. Medical history (including any illness at time of vaccination) included that she was taking antibiotics because she had cancer before, but not less than two weeks before the events. The report was not a customer engagement program. Additional vaccines administered on same date of the Pfizer suspect was reported as none. Family medical history relevant to adverse events were not reported. Concomitant medication included antibiotics. The patient's historical vaccine included first dose of BNT162B2 (COVID Pfizer vaccine, NDC number, Lot number, UPC number, expiry date was reported as unknown) on 12May2021 in left arm for covid-19 immunization. The patient stated that she had called back because she cannot fill out the form due to the loss of use of her right hand. She states she can't type; she can't do anything. Caller stated that she was vaccinated on 12May2021 for the first shot. She stated when the original event happened on the 14May2021 she went to ER on 15May2021 she believes then she had a virtual visit and then went to her pcp. Her doctor wasn't reporting anything, and neither was the ER, and they are the ones who should be. She was pretty sure she almost died. Stated that she had a lot of college educated people all around her trying to help her; they were all at the NCAA gymnastics championships. At first, she just had flulike symptoms, so she thought that she would be fine to go. Caller stated she is 5 foot 1 something and she is probably shrinking. She had sleep apnea and probably congestive heart failure even though it has not been diagnosed they put her on a potassium pill and a water pill. Caller stated that guy wasn't really good and doesn't know much. She'd like to see a new doctor. She would rather leave the doctors information out. She had a friend who is a RN, and caller told her about what happened, and her friend said that was scary but never said anything about blood clots; and said she should probably go to a vascular doctor, but she would need a referral for that and doesn't have one. Her right hand was hurting after the first dose of the vaccine, but her doctor told her that he didn't know what happened during the event she had after the first dose and she was told to just get the 2nd dose. Stated that she was really worried to get the 2nd dose because it was a huge event that happened. She has friends who are lawyers and doctors, and they were all at the NCAA gymnastics championships with her, and it was a huge event that occurred. Afterwards, her right hand was sore, even after her left arm stopped hurting and the event kind of stopped. She doesn't know the exact date that she lost the use of her right hand, but it was the week before last. She kept thinking that it would get better, and she had been putting Voltaren rub on it and everything else, but it was not getting better. The event happened on 14May2021 and it was a 5-hour event, like a clotting attack or something, with a little bit of pause for maybe an hour, and then it started again. After the event stopped, on her right hand where her middle finger connects to her hand, and in the centre of her palm was hurting. All her toes and fingers were going to the sky during that whole attack. Her hand was still sore, and it was still bothering her, but it wasn't on the level that it was. Stated that getting the 2nd dose was like the nail in the coffin for her hand. She didn't have a big clotting event after receiving the 2nd dose; in fact, she didn't even have any flu-symptoms after receiving the 2nd dose; but her hand got way worse. During the whole attack thing, one pupil got huge, and the other pupil stayed normal. Before that it was just her left arm that was hurting, she had flu-symptoms, headache, a bit nauseous, tiredness. She received her injection in her left arm, and it was really sore. During the whole event, it got hot, she had severe pain and pressure in her left arm, and just under her left breast, she sweat so much that it was like she had just gotten out of the shower. She also had severe abdominal pain and cramping; headache and nausea, and she started throwing up during the middle of this whole initial event. She did get blurry vision and her cheeks turned all red. Stated that in her left arm, it felt like things were snaking. She got the 2nd dose of the vaccine; it just crippled her arm. She received the 2nd dose about 3 weeks after the 1st dose but did not provide the date. She does not have her vaccine card and was not entirely sure a full report was done the last time she called. She was scheduled for CAT scan on her hand because since getting the second dose she can't use her hand; she thought there may be blood clots stuck in it. Her fingers on her right hand were discoloured, like bruised, and her palm was bruised; that had been there since the 2nd dose. Her thumb doesn't seem to be to be affected, she can move it; but the rest of her fingers are stuck, she can't straighten them out, they are just stuck in like a claw position. She used to be able to type 65 words a minute blindfolded, and now she can't even hunt and peck because of her hand. She also has trouble going to the bathroom because she can't use her right hand and she is right-handed. The patient underwent lab tests and procedures which included blood test before starting with antibiotic with results unknown. The events required visit to emergency room and physician office.   No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
