Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Influenza infection in solid organ transplant recipients is associated with increased morbidity and mortality compared to non-transplanted controls, due in part to the effects of immunosuppression which is necessary to prevent rejection of the transplanted organ. However, transplant patients are less likely to produce antibodies when vaccinated and when they do, the peak and duration of antibody responses are reduced compared to healthy controls. There are considerable differences in the magnitude of these responses, reflecting variability in individual responses to the influenza vaccine and to the immunosuppression regimen. The investigators hypothesize that chimeric kidney transplant recipients off of immunosuppression will have post vaccine immune responses that are comparable to age and gender matched healthy controls.
