Purpose To evaluate the response and safety of an inactivated vaccine (Sinovac Life Sciences Co., Ltd., Beijing, China) for coronavirus disease 2019 (COVID-19) in liver transplant (LTx) recipients from China. Patients and Methods Thirty-five recipients post LTx from the First Affiliated Hospital of Zhejiang University School of Medicine who received inactivated vaccine from June to October 2021 were screened. Information regarding vaccine side effects and clinical data were collected. Results Thirty-five LTx recipients were enrolled, with a mean age of 46 years, and most patients were male (30, 85.71%). All the participants had a negative history of COVID-19 infection. Predictors for negative response in the recipients were interleukin-2 receptor (IL-2R) induction during LTx, shorter time post LTx and application of a derivative from mycophenolate acid (MPA). No serious adverse events were observed during the progress of vaccination or after the vaccination. Conclusion LTx recipients have a substantially partial immunological response to the inactivated vaccine for COVID-19. IL-2R induction during LTx, a shorter time post LTx and the application of a derivative from MPA seem to be predictors for a negative serological immunoglobulin G (IgG) antibody response in recipients. The findings require booster vaccination in these LTx recipients.
