Plasma TTV load at the time of vaccination (T0). Plasma TTV load at the time of vaccination (T0) is stratified according to group (A; medical personnel [MP], dialysis patients [DP] and kidney transplant recipients [KTR]), and (B) humoral vaccine response. Humoral vaccine response was defined as de novo detection of SARS-CoV-2 S1-IgA and/or -IgG (seroconversion) eight weeks after first vaccination (T1). For statistical analysis, TTV loads were log-transformed and means compared by ANOVA or unpaired t-test. Bars indicate mean. Dotted line indicates limit of detection.
