On an unknown date, the patient experienced BLINDNESS UNILATERAL (I am also blind in my left eye now) (seriousness criteria hospitalization and medically significant), BLOOD POTASSIUM DECREASED (My body will no longer hold potassium \potassium decreased) (seriousness criterion hospitalization) and WHITE BLOOD CELL COUNT INCREASED (my white blood cell count keeps going through the roof\white blood count counts increased) (seriousness criterion hospitalization). At the time of the report, BLINDNESS UNILATERAL (I am also blind in my left eye now), BLOOD POTASSIUM DECREASED (My body will no longer hold potassium \potassium decreased) and WHITE BLOOD CELL COUNT INCREASED (my white blood cell count keeps going through the roof\white blood count counts increased) outcome was unknown.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On an unknown date, Blood potassium: decreased. On an unknown date, White blood cell count: increased.     The action taken with mRNA-1273 BIVALENT .222 (MODERNA COVID-19 VACCINE, BIVALENT (ORIGINAL AND OMICRON BA.4/BA.5)) (Unknown) was unknown.       No concomitant medications were reported. No treatment medications were reported.  It was reported that patient took vaccine and IV and had nothing but medical issues ever since and was even put in the hospital because of it.  Company Comment: This is a spontaneous case concerning a patient of unknown age and gender with no reported medical history, who was hospitalized due to the unexpected, serious (medically significant) event of Blindness unilateral and the unexpected, serious (hospitalization) events of Blood potassium decreased and White blood cell count increased, on unknown date after receiving a dose of mRNA-1273.222 vaccine. Exact date of vaccination, clinical course, relevant diagnostic tests and treatment details were not provided in the case. The outcome of the events were unknown at the time of the report. The benefit-risk relationship of mRNA-1273 is not affected by this report.; Sender's Comments: This is a spontaneous case concerning a patient of unknown age and gender with no reported medical history, who was hospitalized due to the unexpected, serious (medically significant) event of Blindness unilateral and the unexpected, serious (hospitalization) events of Blood potassium decreased and White blood cell count increased, on unknown date after receiving a dose of mRNA-1273.222 vaccine.
