Severe non-cholestatic hepatitis; She never developed hepatic dysfunction; This spontaneous case was reported by a physician and describes the occurrence of HEPATITIS (Severe non-cholestatic hepatitis) and HEPATIC FUNCTION ABNORMAL (She never developed hepatic dysfunction) in a female patient of an unknown age who received mRNA-1273 (Moderna COVID-19 Vaccine) for COVID-19 vaccination.     No Medical History information was reported.    On an unknown date, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. On an unknown date, the patient experienced HEPATITIS (Severe non-cholestatic hepatitis) (seriousness criterion medically significant) and HEPATIC FUNCTION ABNORMAL (She never developed hepatic dysfunction) (seriousness criterion medically significant).

For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter considered HEPATITIS (Severe non-cholestatic hepatitis) to be related. No further causality assessment was provided for HEPATIC FUNCTION ABNORMAL (She never developed hepatic dysfunction).    I have a patient who developed severe non-cholestatic hepatitis, diagnosed about 2 weeks after dose one of her Moderna Vaccine. Lab testing has otherwise been normal with no clear cause. She was on a large volume of supplements and herbs. I believe that was the culprit or possibly an undiagnosed transient viral infection. However the patient is slightly overdue to dose #2 and is worried. Her liver enzymes are improving and she never developed hepatic dysfunction. I could find no data in the literature about case reports of vaccine induced hepatitis. I have asked her to delay dose #2 for another week. Please let me know if you have any guidance for me. She was on a large volume of supplements and herbs. However, the patient was slightly overdue to dose 2 and was worried. She never developed hepatic dysfunction. Doctor had asked her to delay dose 2 for another week.  No concomitant medications were reported. No treatment information was provided.
