NCT03685682

Brief Summary

The investigators plan to study the immunogenicity of the vaccine in VZV-seronegative solid organ transplant recipients. VZV-seronegative patients will be enrolled after organ transplantation. The investigators hypothesize that the recombinant subunit Herpes zoster vaccine is able to induce cellular immunogenicity after transplantation in VZV-seronegative patients.
