GPT and Hepatitis: Patients with liver injury after mRNA vaccines had higher transaminase levels (ALT 26.2x ULN vs. 14.0x ULN, p = 0.003; AST 25.1x ULN vs. 11.2x ULN, p = 0.008) and higher impairment of coagulation (INR 1.3 vs. 1.1, p = 0.012) than those who developed hepatitis after vector vaccines.
