A 73-Year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Formulation: Solution for Injection, Batch/Lot number: Unknown), via intramuscular route of administration in the left arm, on 04Mar2021 10:45 (at age of 73 years old) as dose 2, single for COVID-19 immunisation. Medical history included cholesterol, thyroid, and multiple sclerosis. The patient's concomitant medication's included simvastatin for cholesterol. Historical vaccination included first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE) on an unknown date in Feb2021(also reported as: When probed for first dose date, consumer stated, "I don't know exactly, it was about 6 weeks before then, the patient think it was in February, No, maybe it was 4 weeks the patient think that was in February, January, February then we got in March for the second shot.) for COVID-19 immunisation. On 18Mar2021 (Reported as: 2 weeks later), the patient woke up with terrible vertigo and she thought it was vertigo anyways that was what she have throughout the day, She couldn't see anything really well and she was nauseous, dizzy everything. She spent the day in bed under the coverage so she won't see anything. it was little bit that night that was she kept down but kind of hard to keep it down, she felt little sick. On next day she woke up and she felt little bit better and she was not quite so nauseous and everything.In Mar 2021, she felt like get up and get around and she was still see like everything was wavy like under water and everything she looked up is like under water was moving, everything and she saw some double vision with effect in Mar 2021. It was reported that she had multiple sclerosis and does not had any problem for over 15 years, she thought that she should take that out from. So, she never expressed it be the muscle stroke was because she never once and all these year of she had it, there had not been excavation acted suddenly, So, she was not convinced that it was her multiple sclerosis but she let it walk for several days about a week later on Wednesday, it was like gone again. So that was fine and then she went to easter and then friday after easter it was started again, and it was really bad and so she was not quite as bad as first day in Mar2021. The patient's husband took her to the doctor, and the physician could see her eye was jumping her left to right, when she go to left and jump and she could see it was jumping back and forth in Mar2021, she still waited what it could be. So, the physician called the neurologist's office and they said to go to hospital, they thought she was having a stroke. Then the patient went to the hospital and underwent lots of unspecified tests, and magnetic resonance imaging CAT scan and the patient don't really know what she really had anyway. The patient's cholesterol was slightly high in Mar2021. They did find that there was lesion in my spine and neck and my brain from formal excavation of multiple sclerosis in Mar2021. The physician's checked the patient and confirmed that she doesn't have stroke and so the physician decided it was her MS, but the patient said it probably, she had her shot two weeks before first problem with this, Now he said, that might be something, now they didn't say anything to her but that was they going to look like still they have informed her to stay in hospital for 3 days and they give me Intravenous of cortisone so forth and let her out the hospital and sent her the several doctors including the physiotherapist and MS doctor and she spend lot of hours in the doctor's office. There was a conversation about the COVID stuff, the doctor did not say anything but anyway then had a follow-ups with the doctors with her General Practitioner doctor and said that she should call  and let you know, it was getting improved or was getting better. So she have a movement on her left side little bit, when she move to the left side and things are little bit wavy but anyway it's getting better but he said she thought it should be reported. The patient stated that other than eye sight no other medical conditions were observed after the second shot. Patient stated that her doctor's seems to think that you want follow up information from patient to had some kind of reaction and that's what she was doing to reporting to the Pfizer company that what she had and she was not sure if it was related at all to but she was suspicious because it happened soon after like she said she did not had. It was reported that it did bring some observation, but she did not the same way it usually. So, that's why she thought she should report all this. The patient did not had any other vaccination prior to covid vaccine. The lab test included computerised tomogram: unspecified and magnetic resonance imaging: unspecified. The outcome of the events vertigo, feeling abnormal and illness recovering, cerebrovascular accident, Nausea, visual impairment, dizziness, Diplopia, Feeling abnormal, eye disorder, vision blurred, blood cholesterol high, Central nervous system lesion was unknown.
