The patient medical history included entire colon removed except the last 30cm on an unspecified date, (additional information included in Jan2020 she all of a sudden started having stomach pains. It escalated with her gastrointestinal (GI) tract. Her stomach bloated up huge. It looked like someone had put a basketball in there. The GI doctors did not know what it was. Their son happened to know an international GI endoscopic professor who saw her. She had the entire colon removed except the last 30 cm. The surgery was in Sep2020), anxiety from an unknown date and unknown if ongoing, bladder disorder from an unknown date and unknown if ongoing, low thyroid from an unknown date and unknown if ongoing, Alzheimer from Apr2018 to an unknown date (the patient was diagnosed with Alzheimer in Apr2018) and panicking from Apr2018 to an unknown date (she had been cool, calm, and collective her whole life. In Apr2018 she started panicking. It was bizarre. She thought someone had murdered their neighbor and was after them. Their lives changed in a snap in Apr2018). It was reported that she had a hard time last year as she was diagnosed with Alzheimer's and then reporter (patient caregiver) was diagnosed with Lyme's disease in June2018. Concomitant medications included solifenacin at 10mg daily for bladder disorder from an unspecified start date and ongoing; levothyroxine at 0.05mg daily for thyroid disorder from an unspecified start date and ongoing; potassium chloride at 20mEq once a day (powder mix) for an unspecified indication from an unspecified start date and ongoing; and clonazepam at 0.5mg as needed for anxiety from an unspecified start date and ongoing.

The patient historical vaccine included BNT162B2 (lot number: EL3247) dose 1 upper left arm for COVID-19 immunisation. No additional vaccines administered on same date of vaccination. No vaccine administered within 4 weeks prior of COVID vaccination. On an unspecified date, the patient experienced gradual improvement in her cognitive skills, she fed herself three meals over the weekend and slight swelling around the shot site. The clinical course of the events included: the first dose was three weeks before, 18Jan2021 was the first dose and three days later was when he started noticing things. He would say about the twentieth or twenty first was when he started noticing things. It had been gradual. Little changes over different days. Nothing extreme. The other thing she did that was astounding to him was she walked up to him and asked are you ok then she said that just checking on you. That astounded him. He did not even have internet access where he lives. The husband had to do everything on the hot spot. Hopefully this was a positive side effect. The reporter had spoken to the patient family doctor about this. Her neurologist last time saw the patient he was concerned about the decline. She would just sit in the chair. That was five or six weeks ago. The reporter did send an email to see if any there were any other reports, but he had not heard back. They (patient and her husband) had first COVID vaccination and the second one was a week ago Monday. He noticed a few things she was doing, and it got his curiosity up. There had been a gradual improvement in her cognitive skills. She seemed to be more apparent of her surroundings. She seemed to be comprehending TV shows and was laughing and understanding. She was talking in longer sentences. She had said 4 to 6 words sentences and once a 9 words sentence. Prior to the vaccine if her husband asked her question she would grunt yes or no. Her sense of humour was increasing. She was beginning to putter around the house. She used to be a good housekeeper and husband tried to keep that up, but she was starting to do more with her hands. She was tearing up napkins into square pieces. She was not back to colouring like she used to. What really made him want to call was because she fed herself three meals over the weekend. She had not done that in the past year and a half. Every now and then she would pick up her spoon or fork three or four times during a meal but that was the extent before the vaccines. The outcome of the event slight swelling around the shot site was recovered and outcome of the other events was unknown.
