Additional Information: It was reported that reporter's wife started developing short term memory problems so she was losing short term memory. The patient's memory loss began about 6-7 months ago at least and the caller noticed it and they started realizing she did not remember the things they spoke about 10 minutes later; her long term memory was fine. The short term memory loss was ongoing and persisting and had not gotten any worse but had not improved and they were sitting there talking yesterday and went to the bank the day before and the patient had a safety deposit box and she could remember the number for the box but that was not short term memory. Caller stated the patient and himself both saw the HCP. The HCP, who they addressed that with a few months ago, the HCP said she had heard something to that effect from other people and she experienced that also and the HCP was in their age group and had short term memory loss also; Caller had no names of the product the HCP and the other people were administered and no patient information or lots, expiry dates for the product they received. The patient had the booster shot and they both got it together and he had his card; and on his card it looks like the same shot for Pfizer FJ4984 on 01May but his lot number may be different than hers. The caller states he himself had an appointment with a neurologist the other day and his wife the patient was with him as he went for something else and they mentioned the wife's short term memory loss to the neurologist and the neurologist said he had not heard anything about memory loss because of the shots but there wasn't a lot of study done on that and nothing he could say one way or the other whether it did or did not cause the memory loss. The patient's memory loss was after the booster was administered to her and she was fine up until the booster and the primary care physician told her not to take anymore Pfizer coronavirus shots or other coronavirus shots. The booster dose was administered to the patient in the afternoon to her left arm because she did not want a reaction to happen in her right arm as she was right handed. The strange part about it was that the patient remembers a lot of stuff and they were watching Jeopardy and she can answer a lot of the questions and it was just short term that the issue. They addressed that with their primary care physician several months ago but it was a general visit and the patient goes every 6 months and they brought it up to the doctor. Prior Vaccinations (within 4 weeks): They both had the flu shot; They did get the flu shot but it had been a while and had been getting it every time it's available and got the two flu shots and a few months ago they got the pneumonia shot; no further details provided. The patient's father lived to be in his 80s and her mother died young.
