摘要
Various vaccines against severe acute respiratory syndrome coronavirus 2 have been developed in response to the coronavirus disease 2019(COVID-19)global pandemic,several of which are highly effective in preventing COVID-19 in the general population.Patients with chronic liver diseases(CLDs),particularly those with liver cirrhosis,are considered to be at a high risk for severe COVID-19 and death.Given the increased rates of disease severity and mortality in patients with liver disease,there is an urgent need to understand the efficacy of vaccination in this population.However,the data regarding efficacy and safety of COVID-19 vaccination in patients with CLDs is limited.Indeed,several organ-specific or systemic immune-mediated side effects following COVID-19 vaccination,including liver injury similar to autoimmune hepatitis,have been recently reported.Although the number of cases of vaccine-related liver injury is increasing,its frequency,clinical course,and mechanism remain unclear.Here,we review the current findings on COVID-19 vaccination and liver disease,focusing on:(1)The impact of COVID-19 in patients with CLD;(2)The efficacy,safety,and risk-benefit profiles of COVID-19 vaccines in patients with CLD;and(3)Liver injury following COVID-19 vaccination.
