We will study how well the relatively new FDA approved pneumonia vaccine can protect older renal transplant recipients against pneumococcal illness. We will specifically study the group of renal transplants in whom the cause of renal failure was either diabetes mellitus II and/or hyoertension. We will compare the findings against those we find in younger renal transplant recipients, older healthy individuals and older persons with diabetes but normal kidney function. Healthy younger individuals will serve as controls for optimal vaccine response.
