Clinical Study of SARS-CoV-2 Vaccine in Metabolism-related Fatty Liver Disease

The coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 causes high morbidity and mortality worldwide. SARS-CoV-2 vaccination is currently the most effective means of reducing morbidity, severe illness and mortality risk. Metabolic associated fatty liver disease (MAFLD) has a prevalence rate of 29.63% in China, which is the most common chronic liver disease in China. This study aimed to establish a metabolic associated fatty liver disease (MAFLD) cohort of sequential booster SARS-CoV-2 vaccination, and to identify the dynamic changes of immune response induced by sequential booster SARS-CoV-2 vaccination in MAFLD population. To investigate the effects of blood routine, liver function biochemistry and coagulation function at 28 days, 57 days and 180 days after inoculation of SARS-CoV-2 vaccination. Safety and adverse events were assessed using an electronic questionnaire at days 1, 3, 5, and 7 after enrollment. Serum and peripheral blood PBMC were collected at baseline and 28, 57, and 180 days after vaccination. Blood routine, liver function biochemistry, coagulation function, antibodies, peripheral blood cell subtypes and serum, and PBMC proteomics were tested to evaluate the antibody and immune response induced by SARS-CoV-2 vaccination.
