1.Aging RT
Renal transplant recipients between 65-75 years of age, on stable immunosuppression. who previously (\>1 year prior) received the 23 valent pneumococcal polysaccharide vaccine (pneumovax23). Cause or renal failure was either DMII or HTN. Peripheral blood sample: Peripheral blood samples (30-60 mL) will be collected at day 0 (pre-immune), day 7, and day 30 (4 weeks post-PPV23) for groups 1-4 and at days 366, 373 and 396 for group 5. In addition, day 5, and 10 blood samples will be obtained from a limited (n=10) number of elderly RT participants to determine the optimal time point for circulation of PPS-specific B cells. Yearly blood samples will be obtained thereafter for serum antibody and OPA analyses to test longevity of antibody and OPA responses. Samples obtained from days 0, 30 and yearly samples will be used for antibody titers and opsonophagocytic assays. Samples from day 0 (day of vaccination with PCV13) and day 7 will be used for flow cytometric analysis.
2.Young RT
Renal transplant recipients between 35-45 years of age, on stable immunosuppression. who previously (\>1 year prior) received the 23 valent pneumococcal polysaccharide vaccine (pneumovax23). Cause or renal failure was either DMII or HTN. Peripheral blood sample: Peripheral blood samples (30-60 mL) will be collected at day 0 (pre-immune), day 7, and day 30 (4 weeks post-PPV23) for groups 1-4 and at days 366, 373 and 396 for group 5.

3.Healthy Elderly
Healthy persons between the ages 65-75 who previously (\>1 year prior) received the 23 valent pneumococcal polysaccharide vaccine (pneumovax23) Peripheral blood sample: Peripheral blood samples (30-60 mL) will be collected at day 0 (pre-immune), day 7, and day 30 (4 weeks post-PPV23) for groups 1-4 and at days 366, 373 and 396 for group 5.

4.Elderly DMII or HTN and Normal Renal Function
Persons between the ages 65-75 with DMII or hypertension but normal renal function who previously (\>1 year prior) received the 23 valent pneumococcal polysaccharide vaccine (pneumovax23) Peripheral blood sample: Peripheral blood samples (30-60 mL) will be collected at day 0 (pre-immune), day 7, and day 30 (4 weeks post-PPV23) for groups 1-4 and at days 366, 373 and 396 for group 5.

5.Healthy Young
Healthy persons between the ages 35-45 who previously (\>1 year prior) received the 23 valent pneumococcal polysaccharide vaccine (pneumovax23) or are willing to receive PPV23 and 1 year later Prevnar 13. 23 valent pneumococcal polysaccharide vaccine: FDA approved pneumococcal polysaccharide vaccine containing capsular polysaccharide of 23 different pneumococcal serotypes.

Measure
1.Aging RT
n=9 Participants
Renal transplant recipients between 65-75 years of age, on stable immunosuppression. who previously (\>1 year prior) received the 23 valent pneumococcal polysaccharide vaccine (pneumovax23). Cause or renal failure was either DMII or HTN. Peripheral blood sample: Peripheral blood samples (30-60 mL) were collected at day 0 (pre-immune), day 7, and day 30 (4 weeks post-PPV23) Samples obtained from days 0 and 30 were used for antibody titers and opsonophagocytic assays. Samples from day 7 were used for flow cytometric analysis.
2.Young RT
n=10 Participants
Renal transplant recipients between 35-45 years of age, on stable immunosuppression. who previously (\>1 year prior) received the 23 valent pneumococcal polysaccharide vaccine (pneumovax23). Cause or renal failure was either DMII or HTN. Peripheral blood sample: Peripheral blood samples (30-60 mL) were collected at day 0 (pre-immune), day 7, and day 30 (4 weeks post-PPV23) Samples obtained from days 0 and 30 were used for antibody titers and opsonophagocytic assays. Samples from day 7 were used for flow cytometric analysis.
3.Healthy Elderly
n=12 Participants
Healthy persons between the ages 65-75 who previously (\>1 year prior) received the 23 valent pneumococcal polysaccharide vaccine (pneumovax23) Peripheral blood sample: Peripheral blood samples (30-60 mL) were collected at day 0 (pre-immune), day 7, and day 30 (4 weeks post-PPV23) Samples obtained from days 0 and 30 were used for antibody titers and opsonophagocytic assays. Samples from day 7 were used for flow cytometric analysis.
4.Elderly DMII or HTN and Normal Renal Function
n=9 Participants
Persons between the ages 65-75 with DMII or hypertension but normal renal function who previously (\>1 year prior) received the 23 valent pneumococcal polysaccharide vaccine (pneumovax23) Peripheral blood sample: Peripheral blood samples (30-60 mL) were collected at day 0 (pre-immune), day 7, and day 30 (4 weeks post-PPV23) Samples obtained from days 0 and 30 were used for antibody titers and opsonophagocytic assays. Samples from day 7 were used for flow cytometric analysis.
5.Healthy Young
n=8 Participants
Healthy persons between the ages 35-45 who previously (\>1 year prior) received the 23 valent pneumococcal polysaccharide vaccine (pneumovax23) 13 valent conjugated pneumococcal vaccine: FDA approved pneumococcal polysaccharide vaccine containing capsular polysaccharide of 13 different pneumococcal serotypes conjugated to CRM197 was used for immunization at day 0. Only group 5 received this as an intervention. In all other groups Prevnar 13 will be given as standard of care. Peripheral blood sample: Peripheral blood samples (30-60 mL) were collected at day 0 (pre-immune), day 7, and day 30 (4 weeks post-PPV23) Samples obtained from days 0 and 30 were used for antibody titers and opsonophagocytic assays. Samples from day 7 were used for flow cytometric analysis.
