The events "disoriented for a couple days after the vaccine/cognitive skill loss/continues to be disoriented and its been 13 days since the vaccine", "she can't remember something that he told her an hour ago", "memory loss" and "dizziness" were evaluated at the physician office visit. Additional information: The 68 year old male reporter called on behalf of his 78 year old wife (patient) and was concerned about extended side effects that occurred after their first dose of the Pfizer vaccine on 10Mar2021 at 10AM. He stated that they stayed at the vaccine place 20 minutes after their dose and did not have any immediate reactions. He and the patient both felt weird sensations hours later, but his have since subsided. His wife, the patient, has developed memory loss, severe dizziness, and she can't remember what he told her even half an hour ago. He made an appointment for her to see her doctor that day. His question is if she should still take her second shot, and if that would still be okay if they delay it for up to 30 days. They had pretty bad reactions to it; no fever but both were disoriented for a couple of days after the vaccine. The patient continues to be disoriented and it's been 13 days since the vaccine. Her condition has worsened over the weekend. She is experiencing light-headedness, severe dizziness, as well as she can't remember something that he told her an hour ago. He called his cardiologist who he has a very good relationship with, and the cardiologist's nurse called him back and told him she had had a reaction, but it was more of a flu like reaction. This has continued for a couple weeks and he is very concerned about his wife's reaction. She has severe dizziness as well as real cognitive skill loss. In the sense that he made her an appointment with her general practitioner 30 mins prior, and she did not remember that he had told her that. The reporter asked if these symptoms were being reported; he's only heard of flu like symptoms. He's 69 and his wife is 78 and they have no internet and no smart phones. He's been on hold for an hour and 10 minutes. He's upset that he waited. If he didn't have a phone charger available, he would have had to hang up. His deepest concern is they were both scheduled for the second shot in less than 10 days and the point is that most people have no reaction to the first shot and a heavy reaction with the second shot. If the first shot did this to his wife, he was worried at what the second shot is going to do.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
