On 11 February 2020, the International Committee for the Classification of Viruses named the disease caused by SAＲS-CoV-2 infection in humans as the new coronavirus pneumonia (coronavirus disease 2019, COVID-19). Due to the characteristics of liver microcirculation disturbance and immune function disorder in patients with chronic liver diseases (such as immune liver disease, chronic hepatitis C, liver cirrhosis, liver cancer, etc.), those patients has a higher risk of infection than the general population during the epidemic period. More attention should be paid to personal protection and disease prevention. Vaccination of COVID-19 vaccine can effectively prevent COVID-19 virus infection and delay or prevent patients from developing into critical illness and reduce mortality. To evaluate the safety and effectiveness of COVID-19 vaccine in those patients with chronic liver diseases, and to guide the COVID-19 vaccination more scientifically, reasonably and effectively, this study was carried out.
