A 86-year-old female patient received second dose of bnt162b2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Solution for injection, Batch/Lot Number: EL9266; Expiration Date: 31May2021), via an unspecified route of administration, administered in arm right on 18Feb2021 as 2nd dose, single dose for covid-19 immunisation. The patient medical history and concomitant medications were not reported. The patient previously received first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Solution for injection, Batch/Lot Number: EL9265, Expiry: 20May2021), dose injection to right arm, not too high up on the shoulder. The patient experienced calling to report pain, weakness to right arm, twisted her knee a little bit/folding chair came down and slammed down onto her knee, deep bruise, she hasn't gotten the vaccine for shingles, could only remember the itchy thing, problem with her knee on left side on an unspecified date, second dose hurt when it went in on 18Feb2021, arm had also sort of lost the strength in it too on an unspecified date in Mar2021, arm just reacted strangely, ache, hurt like a toothache just where the vaccine had been placed on an unspecified date in Mar2021. Patient reported that there is a dot where the second dose needle went in her arm. She do not have COVID so assumed she should get it so they could keep living. After the first dose she do not even feel anything, had no reaction to that. The second dose hurt when it went in, but she thought it would go away. So for about 3 weeks she was fine after that. Starting on unknown date in Mar2021, about 3 weeks after she was administered the second dose her arm just reacted strangely, ache, hurt like a toothache just where the vaccine had been placed. It continued that way. Her arm had also sort of lost the strength in it too which still was not returned totally. Events are ongoing, still every once in a while would come back like a toothache; people say it would go away. She asked the expected duration of events; and if potential third dose is or is not recommended relative to events. Patient thought she was about 5 feet and keeps getting shorter, used to be more than 5 feet tall. But she vacuums, moves things around, trying to do what she should do; but events are continuing and she just wondered how long it would continue yet before it went away. Doctor said they would get a third dose of the Pfizer Covid-19 Vaccine, and she do not know whether she should relative to these events. The reason she got the Pfizer Covid-19 Vaccine doses in the right arm is because 2 years ago when she got the flu shot patient had a reaction where site was very red; so she thought she was not going to get injection in the left arm again because she is left handed. She knows that not supposed to get other vaccines, so she has not gotten the vaccine for shingles. The harder she tries to remember the worse it is, then she remembered vaccine for shingles. The physician put cortisone in her shoulder because he said it was something else, that he really do not think it was from the shot. She thought well she has had no accident, no fall, no bang, nothing to produce this other than the shot. He looked at it and gave her some exercises to do, so she was going to continue with therapy at the clinic; she goes to see the lady next week. Before all this happened it was going on and on and on. She had a problem with her knee on left side which the doctor looked at during that appointment. After the Pfizer Covid-19 Vaccine was administered, about 6 weeks ago she was working out in the yard. She do not think it had anything to do with the vaccine. The patient underwent lab tests and procedures which included x-ray: unknown results on unspecified date. Therapeutic measures were taken as a result of calling to report pain, weakness to right arm, second dose hurt when it went in, arm had also sort of lost the strength in it too, twisted her knee a little bit/folding chair came down and slammed down onto her knee, deep bruise, arm just reacted strangely, ache, hurt like a toothache just where the vaccine had been placed, arm just reacted strangely, she hasn't gotten the vaccine for shingles, could only remember the itchy thing, problem with her knee on left side. The seriousness of the events was medically significant. The clinical outcome of arm had also sort of lost the strength in it too, deep bruise were recovering, of the arm just reacted strangely, ache, hurt like a toothache just where the vaccine had been placed were not recovered, of the calling to report pain, weakness to right arm, hurt when it, second dose hurt when it went in, twisted her knee a little bit/folding chair came down and slammed down onto her knee went in, she hasn't gotten the vaccine for shingles, could only remember the itchy thing and problem with her knee were unknown.
