The patient underwent the following laboratory tests and procedures: blood test: showing elevated information; magnetic resonance imaging: unknown results. Patient stated that, patient started having problems with inflammation that had gotten worse and it started like a week or so after, had the second shot. So, patient was wondering if there was any report that had been reported about inflammation and last week patient was told patient had, probably they were going to be doing a biopsy, but they thought there was inflammation on the brain (Further clarification unknown)." Patient stated that, it was probably about 2 weeks, maybe a week after second shot, patient had some symptoms. Patient stated that when patient had the second shot, the day of it, patient's brain just did not want to function at all, and patient just went and rested. About a week, week, and a half, like two weeks later, patient had started noticing vision disturbances and they had stayed. Patient stated that in March patient had these vision disturbances from quite a long time that, since second shot and then it had been progressing. They sent patient for an MRI (Further clarification unknown) and on Friday, they came back and said that the blood test was showing elevated information (Further clarification unknown hence event captured as per verbatim) and because of the eye symptoms, they thought maybe the brain had inflammation (Further clarification unknown)." For the second shot after this happened, that one was LOT# EL9266 and it was given on 27Feb21 (Later clarified as 27Feb). Then patient went to the doctor probably about two weeks later."
