Core Tip

Core Tip: Chronic liver disease patients co-infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exhibited overexpression of angiotensin-converting enzyme 2 receptors and overwhelming cytokine storm. SARS-CoV-2 vaccines can prevent or alleviate severe infection, and cytokine storm. Recently, a question has been raised whether chronic liver disease patients should be vaccinated against coronavirus disease 2019 (COVID-19). The American Association for the Study of Liver Diseases and European Association for the Study of the Liver Expert Panel suggested that all adult patients with chronic liver disease and liver transplant recipients can receive the COVID-19 vaccines using the standard dose and schedule.
