COVID-19 vaccination elicits good humoral response in chronic liver disease patients, while liver transplant recipients show lower response.
Background/Aims: Data of coronavirus disease 2019 (COVID-19) vaccine immunogenicity among chronic liver disease (CLD) and liver transplant (LT) patients are conflicting. We performed meta-analysis to examine vaccine immunogenicity regarding etiology, cirrhosis status, vaccine platform and type of antibody. Methods: We collected data via three databases from inception to February 16, 2022, and reported pooled seroconversion rate, T cell response and safety data after two vaccine doses. Results: Twenty-eight (CLD only: 5; LT only: 18; both: 2; LT with third dose: 3) observational studies of 3,945 patients were included. For CLD patients, seroconversion rate ranged between 84% (95% confidence interval [CI], 76-90%) and 91% (95% CI, 83-95%), based predominantly on neutralizing antibody and anti-spike antibody, respectively. Seroconversion rate was 81% (95% CI, 76-86%) in chronic hepatitis B, 96% (95% CI, 93-97%) in non-alcoholic fatty liver disease, 85% (95% CI, 75-91%) in cirrhosis and 85% (95% CI, 78-90%) in non-cirrhosis, 86% (95% CI, 78-92%) for inactivated vaccine and 89% (95% CI, 71-96%) for mRNA vaccine. The pooled seroconversion rate of anti-spike antibody was 66% (95% CI, 5575%) after two doses of mRNA vaccines and 88% (95% CI, 58-98%) after third dose among LT recipients. T cell response rate was 65% (95% CI, 30-89%). Prevalence of adverse events was 27% (95% CI, 18-38%) and 63% (95% CI, 39-82%) among CLD and LT groups, respectively. Conclusions: CLD patients had good humoral response to COVID-19 vaccine, while LT recipients had lower response.
