Immunity to diphtheria and tetanus in a young population on a dialysis regimen or with a renal transplant.

In 54 transplant recipients diphtheria and tetanus immunity after primary vaccination was significantly lower than in 57 control subject and 35 patients on a dialysis regimen. After a booster, tetanus antibodies developed in the transplant recipients and dialysis patients but no diphtheria antibodies developed in two transplant recipients. No adverse reactions, including acute graft rejection episodes, occurred.
