Alterations of plasma metabolomes and their correlations with immunogenicity in maintenance hemodialysis patients receiving different COVID‐19 vaccine regimens

Maintenance hemodialysis (MHD) patients exhibit compromised immune responses, leading to lower immunogenicity to the COVID-19 vaccine than the general population. The metabolomic factors influencing COVID-19 vaccine response in MHD patients remain elusive. A cross-sectional study was conducted with 30 MHD patients, divided into three vaccine regimen groups (N= 10 per group): homologous CoronaVac
