Brief summary:
The goal of the research proposed in the current application is to first define how much antibody aging renal transplant and dialysis recipients make after they are vaccinated with the pneumonia vaccine and how this compares to similar aged persons with good renal function and healthy young adults. The investigators will study differences in the kind of B cells and markers on the B cells that are known to be important in the response to the pneumonia vaccine in aging renal transplant and aging dialysis recipients compared to similarly aged and young healthy controls. Finally, the investigators will study how safe the pneumonia vaccine is in aging renal transplants. The answers to these questions will help in designing a better vaccine for older people with a renal transplant or on dialysis.

Detailed description:
Objectives / Specific Aims

Individuals \>65 years of age, are the most rapidly growing population amongst those with end stage renal disease (ESRD) and account for more than 18% of renal transplant (RT) recipients.

The incidence of pneumococcal disease is significantly higher in both elderly and those with RT and the combination of these factors is likely additive, if not synergistic, for invasive pneumococcal disease (IPD). It is recommended that both elderly\>65 and RT recipients be vaccinated with a regimen that includes both the 13-valent pneumococcal conjugate vaccine (PCV13) and the 23-valent pneumococcal polysaccharide vaccine (PPV23). However, small immunogenicity studies performed in the transplant populations have not shown superiority of a PCV containing regimen. Moreover, the addition of PCV to the pneumococcal vaccine regimen does not improve protective immunity in this population. Studies to date fail to elucidate the possible foundation of the disappointing immune responses to the PCV regimens.

Specific Aim 1. The investigators will define immune responses by measuring serum antibody and functional antibody responses to PPS 14, 19A and 23F following PCV13 vaccination in RT recipients 65-75 years of age and compare these to: RT recipients 35-45 years of age and persons with DM/HTN but normal function 65-75 years of age to dissect out the age and RT components respectively. Healthy persons 35-45 and 65-75 years of age will be studied as age appropriate reference.

Specific Aim 2. The investigators will measure and characterize the antigen-specific B cell subset response following immunization with PCV13 in the RT recipients 65-75 years of age and compare them to each of the groups described in Specific Aim 1 using flow cytometry and fluorescently labeled PPS and monoclonal antibodies. These measures will be correlated with post-immunization functional antibody activity, a surrogate of protection.

Specific Aim 3. The investigators will measure TNFR expression by B cells following immunization with PCV13 in 65-75 year old RT and compare them to each of the groups described in Specific Aim 1. Gene expression, with focus on the B cell activating factor (BAFF) system, will be measured in PPS-specific and non-PPS specific B cells using single cell genomics and flow cytometry. These measures will be correlated with post-immunization functional antibody activity, a surrogate of protection.

The central hypothesis is that the aging RT population responds poorly to PCV13 vaccination reflecting the combined effects of aging and RT. The investigators postulate that both the number of memory B cells and expression of tumor necrosis factor (TNF) superfamily receptors, which play crucial roles in the response to pneumococcal polysaccharides (PPS), are deficient in the elderly RT population and contribute to poor pneumococcal vaccine responses.

The investigators have developed fluorescently labeled PPS allowing us to study the nature and surface receptors of PPS-specific B cells. The preliminary data demonstrate that RT recipients 1. Respond poorly to pneumococcal immunization as measured by antibody titer and functional antibody activity. 2. RT recipients and healthy elderly have lower absolute number of both IgM and switched memory B cells. 3. The number of PPS-specific IgM and switched memory B cells are significantly lower in RT recipients and 4. TACI and BAFF-R, members of the TNF superfamily receptors, expression is significantly lower in the PPS-specific memory B cells in the RT population versus healthy controls. The overall objective of this proposal is to characterize the immune response and explore possible mechanisms of poor vaccine responsiveness following immunization with PCV in the rapidly growing group of elderly with RT. As the RT population is a heterogeneous group the investigators will study only those in whom the underlying cause of renal failure is diabetes mellitus type 2 (DM2) and/or hypertension (HTN).

Intervention to be studied The intervention to be studied is the immune response to immunization with PCV13 or Prevnar13. This FDA approved vaccine is given as part of the standard of care in Groups 1-4. The experimental part of the protocol in these groups will be blood draws at days 0, 7, 30 and years 1 and 2 in these groups.

In Group 5 two interventions will occur: 1. Immunization with the FDA approved PPV23 or Pneumovax 23 and 2. PCV13 a FDA approved vaccine. In addition, blood samples will be obtained at days 0, 7, 30 year 1 and year2.

Both PPV23 and PCV13 are FDA approved vaccines for use in humans. PCV13 is recommended for all individuals enrolled in Groups 1-4. It is not recommended as routine part of care in Group 5 enrolled individuals however it has never shown to be harmful in this group of individuals.

Study Endpoints The primary endpoint of this study is: quantify the antibody titers in mg/mL and opsonophagocytic antibody titer calculated as serum dilution, number of polysaccharide specific B cells, and absolute number of cells/mL induced by vaccination with PCV13.

Secondary endpoint of the study is to describe differences in gene expression of 56 genes to be determined by single cell PCR and comparing these between groups.

The primary safety endpoint of the study is measured as minimal versus moderate local side effect. Minimal side effect measured as no impairment in activity. Moderate local side effect is a side effect affecting use of the extremity for less than 24 hours.

Inclusion and Exclusion Criteria/ Study Population: as described in inclusion/exclusion section

Study Design / Methods The overall objective of this proposal is to characterize the immune response and explore possible mechanisms of poor vaccine responsiveness following immunization with PCV in the rapidly growing group of elderly with RT. As the RT population is a heterogeneous group the investigators will study only those in whom the underlying cause of renal failure is diabetes mellitus type 2 (DM2) and/or hypertension (HTN). There will be 5 study groups as outlined above.

results obtained in various groups will be compared.

Timing of blood samples Peripheral blood samples 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. BAFF concentration will be measured at day

The vaccine(s) administered to the participants are FDA approved vaccinations and vaccination protocols. The standard and recommended dose of vaccine will be administered either by a qualified nurse or physician and both vaccines are considered low risk. In groups 1-4 PCV13 will be administered per standard of care and is not part of the experimental protocol. In group 5, both PPV23 and PCV 13 are not routine part of care and are part of the experimental protocol. These vaccines have however been extensively studied in this and other populations and are considered low risk and 70-80% protective against pneumococcal disease.

The risk associated with blood draws is minimal.

Objectives / Specific Aims 
 
Normal aging is characterized by changes in the immune system that result in increased susceptibility to 
infections, poor response to new vaccine antigens, loss of protection offered by previous vaccinations and 
decreased immune surveillance [1, 2]. Despite the chronic inflammation associated with 
immunosenescence, the aging population is living longer. Consequently, individuals >65 years of age, are 
the most rapidly growing population amongst those with end stage renal disease (ESRD) and account for 
more than 18% of renal transplant (RT) recipients [3]. 
The incidence of pneumococcal disease is significantly higher in both elderly [4] and those with RT [5 ] 
and the combination of these factors is likely additive, if not synergistic, for invasive pneumococcal disease 
(IPD). It is recommended that both elderly>65 and RT recipients be vaccinated with a regimen that includes 
both the 13-valent pneumococcal conjugate vaccine (PCV13) and the 23-valent pneumococcal 
polysaccharide vaccine (PPV23). However, small immunogenicity studies performed in the transplant 
populations have not shown superiority of a PCV containing regimen [6, 7]. Moreover, the addition of PCV 
to the pneumococcal vaccine regimen does not improve protective immunity in this population. Studies to 
date fail to elucidate the possible foundation of the disappointing immune responses to the PCV regimens, 
data essential for the development of a rational and effective next generation pneumococcal vaccine.  
Specific Aim 1. 
We will define immune responses by measuring serum antibody and functional antibody responses to 
PPS 14, 19A and 23F following PCV13 vaccination in RT recipients 65-75 years of age and compare these 
to: RT recipients 35-45 years of age and persons with DM/HTN but normal function 65-75 years of age to 
dissect out the age and RT components respectively. Healthy persons 35-45 and 65-75 years of age will be 
studied as age appropriate reference.  
Specific Aim 2. 
We will measure and characterize the antigen-specific B cell subset response following immunization with 
PCV13 in the RT recipients 65-75 years of age and compare them to each of the groups described in Specific 
Aim 1 using flow cytometry and fluorescently labeled PPS and monoclonal antibodies. These measures 
will be correlated with post-immunization functional antibody activity, a surrogate of protection. 
Specific Aim 3. 
We will measure TNFR expression by B cells following immunization with PCV13 in 65-75 year old RT 
and compare them to each of the groups described in Specific Aim 1. Gene expression, with focus on the B 
cell activating factor (BAFF) system, will be measured in PPS-specific and non-PPS specific B cells using 
single cell genomics and flow cytometry. These measures will be correlated with post-immunization 
functional antibody activity, a surrogate of protection. 
Our central hypothesis is that the aging RT population responds poorly to PCV13 vaccination reflecting the 
combined effects of aging and RT.   We postulate that both the number of memory B cells and expression 
of tumor necrosis factor (TNF) superfamily receptors, which play crucial roles in the response to 
pneumococcal polysaccharides (PPS), are deficient in the elderly RT population and contribute to poor 
pneumococcal vaccine responses. 
We have developed fluorescently labeled PPS allowing us to study the nature and surface receptors of PPS-
specific B cells.  Our preliminary data demonstrate that RT recipients 1. Respond poorly to pneumococcal 
immunization as measured by antibody titer and functional antibody activity. 2. RT recipients and healthy 
elderly have lower absolute number of both IgM and switched memory B cells. 3. The number of PPS-
specific IgM and switched memory B cells are significantly lower in RT recipients and 4. TACI and BAFF-
R, members of the TNF superfamily receptors, expression is significantly lower in the PPS-specific memory 
B cells in the RT population versus healthy controls. The overall objective of this proposal is to characterize 
the immune response and explore possible mechanisms of poor vaccine responsiveness following 
immunization with PCV in the rapidly growing group of elderly with RT. As the RT population is a

mellitus type 2 (DM2) and/or hypertension (HTN).

Background 
 
Streptococcus pneumoniae is the most common bacteria isolated from the elderly with community acquired 
pneumonia [8].  The elderly are at high risk of pneumococcal infection, have an increased incidence of 
blood stream infection and a higher mortality rate compared to younger adults [4]. It is projected that 
between 2000 and 2040, the number of Americans ≥65 years of age will more than double.  The rapid 
growth of the aging population has resulted in a significant increase in elderly individuals with end-stage 
renal disease (ESRD). In 2014, there were >300,000 older adults with ESRD, a seven-fold increase 
compared to the 1990’s [3]. In addition, individuals with ESRD are living longer, disproportionally 
increasing the number of elderly with ESRD [9].  Moreover, older (>65 yrs) individuals now account for 
18.4% of the 17,000 renal transplants performed in the US annually [3, 10] and are by far the fastest growing 
population requiring renal replacement therapy, i.e. dialysis or renal transplantation [11]. Although the renal 
transplant (RT) population is susceptible to a host of infections, S. pneumoniae is the most common 
bacterial respiratory pathogen and the incidence of invasive pneumococcal disease (IPD) is estimated to be 
12.8 fold higher than in the general population [5]. Moreover, aging individuals with RT have two distinct 
risk factors for pneumococcal disease, namely age and RT accounting for the high incidence of disease in 
this population. 
Accordingly, pneumococcal vaccination is recommended for all adults≥65 years of age and all RT 
recipients [12, 13]. In 2012 the vaccination recommendations by the Advisory Committee on Immunization 
Practices (ACIP) for these immune compromised adults, were changed to include vaccination with the 13-
valent pneumococcal conjugate vaccine (PCV13) [12]. Although highly successful in infants, 
immunogenicity studies have overall failed to demonstrate superiority of PCV based regimens in older 
adults [14]. Similarly, a prime-boost regimen based on sequential immunization with PCV7 and the 23-
valent pneumococcal polysaccharide vaccine, Pneumovax® (PPV23), has not demonstrated improved 
responses in RT and liver transplant populations [6, 7]. The RT population ≥65 years of age is rapidly 
growing and represents a unique subpopulation with combined immunodeficiencies related to aging [15] 
and immunosuppressive drugs related to transplant.  Both aging and RT result in a marked increased risk 
of pneumococcal disease with decreased immune response to pneumococcal vaccination. The immune 
response to vaccination with PCV is poorly characterized in the aging and transplant populations, and may 
not be more effective than PPV23 alone, implying the need for alternate vaccine/adjuvant strategies. 
Moreover, studies characterizing and comparing antigen-specific B cell responses in well-defined RT 
populations are lacking. 
We have developed directly labeled fluorescent PPS to enumerate and characterize PPS-specific B cells. 
This allowed the analysis of antigen-specific B cell responses to pneumococcal vaccination. The results of 
these studies demonstrated that the immune response to PPV in young adults consists predominantly of 
IgM memory B cells [16].  In contrast, in the elderly who are deficient in memory B cells, particularly IgM 
memory B cells [17], the predominant B cell phenotype in response to PPS consists of switched memory B 
cells (IgG/A+IgM-CD27+)[18]. HIV+ individuals, are also deficient in CD27+IgM+ B cells yet the 
predominant response consists of PPS-specific CD27+IgM+ B cells [19-22], albeit at significantly reduced 
numbers. Thus, the cause of poor pneumococcal vaccine responses varies according to study population.  
Several investigators and our preliminary data show that like the elderly and HIV-positive, absolute number 
and percentage of memory B cells are significantly lower in stable RT recipients, at 6 months to 5 years 
post-RT, compared to healthy subjects [23, 24]. Moreover, low number and percentage of IgM memory B 
cells correlate with poor antibody responses to PPV23.  
This may however not be the only cause for poor vaccine responses.  The ability to isolate antigen-specific 
B cells allows us to explore other deficits and/or changes in surface markers and gene expression potentially 
implicated in poor vaccine responses.  It has been well described that members of the TNFR family and 


 
Page 4 of 18 
 
certain Toll like receptors (TLR) play a crucial role in the immune response to pneumococcal vaccination 
[25, 26 ]. As shown in preliminary data, we have found decreased TACI and BAFFR expression in PPS-
specific B cells derived from RT recipients. Although the number of RT recipients studied is very small, it 
was a consistent finding and merits further study. Adjuvants that specifically upregulate TACI expression, 
such as CpG-ODN, could therefore effectively increase immune responsiveness to pneumococcal vaccines. 
This strategy has shown to increase immune and memory responses to the conjugate pneumococcal vaccine 
in HIV-positive persons [27 ]. Our central hypothesis is that the elderly RT population responds poorly to 
PCV13 reflecting combined effects of aging and RT that result in abnormalities in both number of memory 
B cells and TNF superfamily expression, which play crucial roles in the response to polysaccharide 
antigens. We will test this hypothesis by measuring PPS-specific antibody and opsonophagocytic antibody 
responses, PPS-specific B cell phenotypes and surface and gene expression of the TNFR with known role 
in response to pneumococcal vaccination and correlate these individually with antibody and functional 
antibody responses. This has important clinical implications as deficient TNFR expression can be 
modulated by the addition of adjuvants such as CpG-ODN. 
Preliminary Data 
Over the past 16 years, the PI’s laboratory has studied the immune response to pneumococcal vaccination. 
All of these studies have been performed in humans. Initially these studies were focused on the elderly 
population.  We defined immune response, functional antibody activity and antibody (V) gene usage in this 
population.  We have developed unique directly labeled fluorescent pneumococcal polysaccharides (PPS).  
This has allowed us to focus on the antigen-specific B cell response.  The PPS-specific immune response, 
including antibody response, functional activity and B cell phenotype analysis have been performed by us 
following pneumococcal polysaccharide vaccination (PPV23) and/or pneumococcal conjugate vaccine 
(PCV13), in young and elderly (>65 yrs) healthy persons as well as young (<50) and aging (50-65 yrs) 
HIV+ persons.  These studies were published in Journal of Immunology, Journal of Infectious Diseases, 
Vaccine, PlosOne and the Journal of AIDS and Clinical Research . These studies have formed the basis for 
comparative analysis of the immune response following PCV13/PPV23 in elderly and HIV+ individuals.  
The results of these studies demonstrated unique B cell deficiencies in HIV and elderly.  We are in a unique 
position to perform an in-depth analysis of the immune response to PCV13 in the aging renal transplant 
population, defining surrogates of efficacy and safety. Despite the recent change in vaccine 
recommendation, based on expert opinion, studies demonstrating superiority and safety of PCV has not 
been performed in an adequate manner in the past. In addition, we will explore the mechanism of poor 
responses, laying a foundation for development of more effective vaccines for this population of elderly. 
 
3.0 
Intervention to be studied (if applicable) 
The intervention to be studied is the immune response to immunization with PCV13 or Prevnar®13. 
This FDA approved vaccine is given as part of the standard of care in Groups 1-4. The experimental 
part of the protocol in these groups will be blood draws at days 0, 7, 30 and years 1 and 2 in these 
groups. 
In Group 5 two interventions will occur: 1. Immunization with the FDA approved PPV23 or 
Pneumovax® 23 and 2. PCV13 a FDA approved vaccine. In addition, blood samples will be 
obtained at days 0, 7, 30 year 1 and year2. 
 
Both PPV23 and PCV13 are FDA approved vaccines for use in humans. PCV13 is recommended 
for all individuals enrolled in Groups 1-4. It is not recommended as routine part of care in Group 5 
enrolled individuals however it has never shown to be harmful in this group of individuals.

The primary endpoint of this study is: quantify the antibody titers in mg/mL and opsonophagocytic 
antibody titer calculated as serum dilution, number of polysaccharide specific B cells, and absolute 
number of cells/mL induced by vaccination with PCV13. 
Secondary endpoint of the study is to describe differences in gene expression of 56 genes to be 
determined by single cell PCR and comparing these between groups. 
The primary safety endpoint of the study is measured as minimal versus moderate local side effect. 
Minimal side effect measured as no impairment in activity. Moderate local side effect is a side effect 
affecting use of the extremity for less than 24 hours.

Inclusion and Exclusion Criteria/ Study Population 
 
Age ranges were chosen based on previous published and unpublished studies performed in our laboratory 
indicating that a significant decrease in pneumococcal vaccine response starts to appear at age 65 and that 
prior to age 50 the response is similar to individuals 20-30 age of years, i.e. optimal range. We chose the 
35-45 age group specifically, and not 20-30, as renal transplants recipients with cause of renal failure is 
type II diabetes or hypertension are well represented in the MUSC transplant population. 
 
Individuals will be screened for eligibility depending on the group they are recruited for: 
Group 1 Older RT group (Age 65-75)  
Group 2 Younger RT group (Age 35-45) 
The elderly (65-75 years) and young (35-45 years) renal transplant recipient groups 1 and 2 seen at the 
MUSC and VA transplant clinics whose end-stage renal disease was caused by hypertension (HTN) and/or 
DM II who are at least 1 year post-transplant and due for their PCV 13 vaccination will be asked to 
participate in the study.  Those that do not wish to participate in the study will receive the clinical standard 
of care. 
 
Group 3 Individuals with DM II and/or HTN age 65-75. 
Individuals with the diagnosis DM II and/or HTN due for routine visits at the general internal medicine or 
endocrinology clinic at the Ralph H Johnson VA Medical Center will be screened for normal (Glomerular 
filtration rate≥60) versus abnormal (GFR<60) who are due for their standard of care PCV13 vaccine will 
be asked to participate. 
 
Group 4: 65-75 years old without DM2 or renal impairment who are due for their standard of care 
vaccination with PCV13. 
 
Group 5: Healthy persons 35-45 years of age without DM or renal impairment willing to participate in a 
study to receive PPV23, if they have not received this previously or/and PCV13, at least 1 year after PPV23 
vaccination. 
 
Inclusion/Exclusion criteria 
 
Inclusion criteria are group specific. HBV, HCV and HIV testing are not necessary in the RT groups as all 
RT recipients are tested prior to transplant. 
Exclusion criteria are either applicable to all groups or group specific. Therefore we have listed the 
exclusion criteria applicable to ALL groups first. Group specific criteria are listed under each group 
 
Exclusion Criteria common to all groups

Diversity: we will attempt to mimic the local renal transplant recipient population consisting of a 
disproportionately high number of males (>60%) of African-American decent, ±50%. This gender and race 
pattern of distribution is consistent with the patient population of the Ralph H. Johnson VA Medical Center 
outpatient clinics, where we will be recruiting most of our control populations (Groups 3-5). We therefore 
anticipate a diverse population as a result of eligibility at the recruitment sites. 
Children will NOT be included in this study as this study is uniquely aimed at defining the immune 
response to PCV13 in ADULTS. The immune response to PCV13 is age-dependent and therefore 
completely different in children, as is the recommended vaccine frequency.

Recruitment Methods 
 Potential study participants will be recruited from Ralph H. Johnson Veterans Affair Medical 
Center and Medical University of South Carolina during the appointment with their treating 
physician. Flyers will be posted in the waiting room areas of the clinics and attending 
physicians and clinic nurses will be asked to keep this study in mind and mention availability 
of these studies to their patients when ordering PCV13 for them. 
 Potential study subjects will be explained the purpose of the study and how their information 
was obtained (from a treating physician or a chart review); further the eligibility criteria will 
be explained and what involves in participating in the study: procedures, estimated time of 
commitment, any reasonably foreseeable risks, benefits, and compensation. In a similar 
manner, healthy volunteers will be recruited through flyer advertisement on MUSC campus 
as well as in VA. 
 Potential study subjects will be identified by reviewing medical records and by physician’s 
recommendations. 
 Flyers will be used to recruit study subjects as well as broadcast emails for MUSC and VA 
employees and volunteers.

Consent Process 
Informed Consent will be obtained in a private room from all participants at either: 
1. The MUSC Renal Transplant clinic is located on the 9th floor of the Rutledge Tower 
Or 2.The nephrology clinic at the Ralph H. Johnson VA Medical Center  
Or 3. the P.I.’s laboratory at the Strom Thurmond Building Room 411  
 
Consent will be sought of competent adults who express interest in the study. The purpose of the study, 
the study details regarding gathering health information and obtaining blood samples, the potential benefit 
and risks involved, including risk of blood draw and vaccination, will be explained in detail and in layman 
terms, as well as the non-standard of care explained to the potential subject (i.e. blood draws for groups 1-
4, vaccination protocol and blood draws for group 5).  The subject will be encouraged to ask questions and 
they will be asked to answer questions regarding essential parts of the study to ensure proper understanding 
of the study requirements.  We will explicitly explain that the study is completely voluntary, and they can 
withdraw from the study at any time.  Additionally we will explain that participation is independent of the 
medical care the subject receives at the Ralph H Johnson VA medical center or MUSC. 
Consent will be obtained as described above in the presence of the P.I. or study coordinator. The potential 
volunteer will be given written information, and opportunity for questions will be provided. Volunteers will 
be questioned concerning the study to assure complete understanding. 
The consent will only be obtained from the participant him or herself and not from a surrogate. 
There will be no waiting period between consent and beginning of the study 
The study and consent form will be reviewed in depth and after each separate section the participant will 
be asked to summarize the section in his or her own words to ensure understanding. 
 
Vulnerable populations, i.e. employees at the P.I.'s institution will be recruited, however they will ONLY 
be recruited if they have 
1. no personal relationship with the PI 
2 are not directly employees of the PI or a division where they could be vulnerable to coercion or undue 
influence.

Study Design / Methods 
The overall objective of this proposal is to characterize the immune response and explore possible 
mechanisms of poor vaccine responsiveness following immunization with PCV in the rapidly growing 
group of elderly with RT. As the RT population is a heterogeneous group we will study only those in whom 
the underlying cause of renal failure is diabetes mellitus type 2 (DM2) and/or hypertension (HTN). There 
will be 5 study groups as outlined above.  
Volunteers from all 5 study groups will be recruited as above. All individuals from study groups 1-4 who 
meet the study criteria will receive Prevnar13® on day 0. Group 5 volunteers will be recruited during the 
first year of the study and those who have not previously received PPV23 will receive PPV23 on day 0 and 
PCV13 on day 366. Blood samples will be obtained as outlined below and results obtained in various groups 
will be compared. 
 
Timing of blood samples 
Peripheral blood samples 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 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. The day 7 time point for 
isolation of antigen-specific B cells was specifically chosen as we have extensively studied temporal 
dynamics of antigen-specific B cell in peripheral blood samples (unpublished studies) and have found that 
the highest number of antigen-specific B cells are present in the peripheral circulation at day 6 and 7 with 
rapid (70+%) decline at day 8 in healthy young, elderly including those with DM2 and HTN, and HIV-
positive. At day 30, a minimal number of PPS-specific B cells were present. Others have described similar 
findings [28, 29]. 
However, it is possible that day 7 may not be the optimal time point for the isolation of antigen-specific B 
cells in the RT populations. Therefore, we will obtain blood samples on days 5, 7, and 10 from the first 10 
participants in the aging RT group to redefine optimal time point for antigen-specific B cell isolation in this 
population. The first 10 participants in Group 1 will be recruited from both MUSC and the VAMC. The 
optimal time point will be applied to all subsequent RT participants. 
BAFF concentration will be measured at day 0. 
 
 
All groups: All recruited subjects will agree to be tested for HIV by rapid HIV test, HBsAg and HCV if 
their status is not available in their health records. In addition they will agree to have CBC and Complete 
metabolic profile (CMP) and hemoglobin A 1c (HbA1c) should a recent (<6 months old) result not be 
available. 
 
Groups 1-4 
 
All individuals in groups 1-4 agree to  
1. Receive PCV13 (Prevnar®13): this is STANDARD of care in all group 3 recruited and enrolled 
subjects 
2. Experimental part of the protocol they will agree to: 
In the first 10 vaccine recipients in groups 1 : donate blood specimens: at 7 different times of up 
to 60 mL per visit: day 0, day of vaccination: at day 5, day 7, day 10 and at day 30 and yearly 


 
Page 10 of 18 
 
thereafter up to 2 years. Samples drawn at days 5, 7 and 10 are used to determine the optimal time 
point of isolation of PPS-specific B cells.  
Participants 11-40 in group 1 and all Group 2: will donate blood samples at 5 different time points 
of up to 60 mL per visit: day 0, day of vaccination: at optimal time point being either day 5 or 
day 7 or day 10 and at day 30 and yearly thereafter up to 2 years. 
The optimal time point of isolation of PPS-specific B cells post-vaccination in both young and 
elderly healthy and diabetic populations had been determined by us in previous studies, however 
this may vary in the transplant population. We will therefore test this in the first 10 RT subjects 
enrolled in both groups 1 and 2. The first 10 participants in Group 1 will be recruited from both 
MUSC and the VAMC. 
 
Groups 3 and 4: There will be 5 visits: blood draws of up to 60 mL per visit: day 0, day of 
vaccination: at day 7  and at day 30 and yearly thereafter up to 2 years. 
 
Group 5 
1. Receive PPV23 (Pneumovax®) on day 0 of enrollment if they have never received PPV23. This 
is to assure that all participants in the study have been immunized with PPV23 at least 1 year prior 
to receiving PCV13. 
2. Receive PCV13 (Prevnar®13) on day 366 
2. Experimental part of the protocol they will agree to: 
All vaccine recipients donate blood samples up to 60mL per visit: at 5 different times: day 366 
day 373, 396 and yearly thereafter up to 3 years, i.e. referred to years 1, 2 and 3. 
 
In group 5, healthy 35-45 year olds, PPV23 and PCV 13 may not be routine part of care (in those without 
any underlying disease or tobacco use) and vaccination with PCV13/PPV23 is not part of routine care in 
any of these individuals, however neither vaccination regimen is contra-indicated in these age groups 
and is NOT associated with a higher rate of adverse events exceeding vaccination in other age groups. 
In fact, significant benefit may be derived from either vaccine regimen.

The vaccine(s) administered to the participants are FDA approved vaccinations and vaccination protocols. 
The standard and recommended dose of vaccine will be administered either by a qualified nurse or 
physician and both vaccines are considered low risk. In groups 1-4 PCV13 will be administered per 
standard of care and is not part of the experimental protocol. In group 5, both PPV23 and PCV 13 are not 
routine part of care and are part of the experimental protocol. These vaccines have however been 
extensively studied in this and other populations and are considered low risk and 70-80% protective 
against pneumococcal disease [30]. 
The risk associated with blood draws is minimal.

Data Management  
Statistical Analysis Plan and Sample Size Justification for Aims 1 and 2  
The primary outcomes in Aim 1 are serum antibody levels and functional antibody response measured using 
the OPA response at baseline and 30 days post-PVC13 vaccine measured in the five groups defined in Table 
1.  The primary outcomes in Aim 2 are absolute number and proportion of B-cells phenotype specific to 
PPS14, 19A, and 23F at baseline and 7 days post-PVC13 vaccine measured in the same five groups. 
Comparisons between groups and within group between times for each aim will be evaluated using a linear 
mixed model (LMM) approach.  The models will include fixed 
effects for participant group (65-75 RT, 35-45 RT, 65-75 
DM/HTN, 65-75 healthy, and 35-45 healthy) and for time 
(day 0 or 30) and a random subject effect to account for 
repeated measures of antibody levels within participant.  Model 
assumptions will be checked graphically and transformations 
will be considered when necessary.  Comparisons for each 
outcome between groups and within group between times will 
be evaluated using a series of contrasts from the LMM.  We are 
presenting power calculations for a range of assumptions to 
demonstrate that we anticipate having sufficient power to detect 
observed differences for all comparisons even if we fail to meet 
the recruitment target.  For power calculations we estimated the 
effect sizes for sample sizes ranging between 10 to 40 
participants per group measured at 2 times at 80% and 90% 
power using a two-sided test assuming within subject correlation 
of 0.5 and Bonferroni adjusted and unadjusted significance 
Figure 7: Effect sizes for different 
sample sizes, power, and significance 


 
Page 14 of 18 
 
levels of p = 0.005 and 0.05 respectively.  We will also evaluate the correlation between serum antibody 
levels and B cell count with OPA response across all participant groups using an LMM approach where 
OPA response is the dependent variable and antibody level or B-cell count is the independent variable.  The 
model will include a random subject effect to account for repeated measures in the same subject.  We 
anticipate good correlation (between 0.6-0.99), thus the objective is to estimate the correlation and define 
the level of precision around that correlation.  A sample size of 200 subjects, 40 per group, provides >80% 
power to detect weak correlations of r = 0.20 and allows us to estimate a 95% confidence interval around 
the correlation to within ± 0.14.  
Statistical Analysis Plan and Sample Size Justification for Aim 3 
 Aim 3 will examine differences in expression of TNFR markers (TACI, BCMA, and BAFF-R) using single 
cell qPCR on a subset of 10 participants (5 responders and 5 non-responders) from each of the 5 groups 
described in Aims 1 and 2 evaluated at baseline and 7 days post-vaccination.  Single cell qPCR allows us 
to not only evaluate differences in expression between groups but also allows us to estimate the within 
subject and within group heterogeneity with great precision.  Each participant sample provides between 40-
96 viable cells that will be evaluated for gene expression at the single cell level.   Relative fold-change in 
expression between participants who are 65-75 RT, 35-45 RT, or 65-75 DM/HTN with respect to the 
relevant controls will be evaluated using a linear mixed model approach.  The model will include fixed 
effects for participant group, response status, and time and a random subject effect to account for repeated 
measurements resulting from individual cells from the same subject samples.  Comparisons of number of 
gene expression between groups and within group between times will be evaluated using a series of 
contrasts from the LMM.  For comparisons within group between responders and non-responders, a sample 
size of 5 responders and 5 non-responders with > 40 cell level measures at 2 time points provides 80% 
power to detect 2.7 fold-increase or a 0.60 fold-decrease in expression using a two-sided test assuming 
within subject correlation of 0.5 and a Bonferroni corrected significance level (up to 10 comparisons) of p= 
0.005.  For comparisons between groups, we will have 10 subjects per group allowing us to detect even 
smaller fold-changes in expression.  
 
All electronic data will be kept on the VA secure V drive or R drive and on MUSC secure Z drive that only 
team members will have access to.

Provisions to Monitor the Data to Ensure the Safety of Subjects (if applicable) 
All adverse events (AE) will be reported and monitored through the data safety monitoring plan. The AE’s 
will be characterized by: intensity/severity; expectedness; relatedness; frequency; outcome; treatment or 
action taken.  
Monitoring will be performed at each study visit by the study coordinator and/or P.I. and will occur at the 
Ralph H. Johnson VA Medical Center and MUSC and all AEs will be recorded on an event form with 
physician/nurses/coordinator notes attached. These will be reviewed by the safety monitoring committee 
The safety monitoring committee will include board certified Infectious Diseases specialists. Meetings will 
occur on a quarterly basis. Dr. Westerink, the P.I. will arrange for the meetings quarterly, make all materials 
available for review by the committee and be ultimately responsible for the meetings. 
The study endpoints will be reporting and assessing safety of the vaccination and blood draw procedures 
and to ensure that these procedures are well within the acceptable complication risk associated with 
vaccination and blood draws.  
All serious, unexpected, AND related adverse events will be reported to the MUSC IRB within 10 working 
days of learning of the event.   
 
14.0 Withdrawal of Subjects (if applicable) 
Subjects will only be withdrawn from the study for failure to appear at day 7 and day 30, the 2nd and 
3rd visit of the study, at which times crucial blood samples are to be obtained. This may occur 


 
Page 15 of 18 
 
voluntarily at the participant’s discretion or due to unforeseen circumstances. Should this occur, no 
further study visits will be requested and no further visit payments will be made.  
15.0 
Risks to Subjects 
Risks to subjects are minimal. This study involves immunization with an FDA approved vaccines which 
are standard of care for all study groups included with the exception of the young healthy group.  Small 
volume blood draws will be performed at various time points before and after vaccination as outlined above. 
The risks associated with blood draws is minimal and may result in minor hematomas at the blood draw 
site and/or bleeding. The blood samples, lymphocytes and cDNA will not be marked with donor identifiable 
data. The risk of breach of confidentiality is minimal, all staff associated with the project have completed 
appropriate training in human subject research regulations and policies (including the Health Information 
Portability and Accountability Act (HIPAA). 
We will obtain IRB approval at the VA/ MUSC in compliance with Federal Regulations, state and local 
laws and institutional policy governing human subject research. Following informed consent, all volunteers 
who choose to participate in this research will complete a questionnaire to evaluate their overall health and 
eligibility. The vaccination protocol and blood draw schedule will be explained in detail. The risks of blood 
draws and vaccination with the conjugated pneumococcal polysaccharide vaccine will be explained and the 
intent to isolate their lymphocytes for the use in flow cytometry and other molecular biology experiments 
for further study will be outlined as part of the informed consent process prior to any specimens being 
obtained. 
Possible side effects of blood draws (approximately 60 mL/visit) may be the risk of pain, small bruises and 
bleeding, or infection.  All blood draws will be done by experienced technicians or an experienced medical 
doctor under sterile conditions with proper measures to prevent risks and pain.  There are no long term risks 
associated with blood draws.  
Vaccination with the pneumococcal vaccine is linked with side effects that are usually considered minor 
side effects. In adults aged 18 years and older, the most commonly reported solicited adverse reactions 
(>5%) PCV13, or Prevnar were pain at the injection site (>50%), fatigue (>30%), headache (>20%), muscle 
pain (>20%), joint pain (>10%), decreased appetite (>10%), injection site redness (>10%), injection site 
swelling (>10%), limitation of arm movement (>10%), vomiting (>5%), fever (>5%), chills (>5%), and 
rash (>5%). The most common adverse reactions, reported in >10% of subjects vaccinated with PPV 23 or 
Pneumovax in clinical trials, were: injection-site pain/soreness/tenderness (60.0%), injection-site 
swelling/induration (20.3%), headache (17.6%), injection-site erythema (16.4%), asthenia and fatigue 
(13.2%), and myalgia (11.9%). Sometimes an allergic reaction can occur but this is very rare. The side 
effects are seldom more severe and may consist of fever, redness at the site of injection with lymph node 
swelling in the armpit which may last up to 3 days. This occurs rarely. It should be noted that pneumococcal 
vaccination (PCV13) is recommended for all RT recipients and all individuals >65 years of age where it is 
considered standard of care. All individuals in groups 1-4 will already have received PPV23 as part of their 
routine health care. Although both PPV23 and PCV13 vaccines are FDA approved , two vaccine regimen 
is not routine as standard of care in healthy HIV negative persons <65 although it is safe, so this vaccination 
is experimental in this use. Thus as healthy young control group, 35-45 years of age, an essential part in 
this study for comparator reasons, we will immunize with PPV23 a year before immunizing them with 
PCV13 so that all groups have received both PPV23 followed by PCV13. Again, a step absolutely necessary 
and safe, to generate interpretable data from this study. 
All paperwork containing donor identifiable data is held in a locked file cabinet in the office of the PI. Each 
donor is assigned a random number and all samples resulting from that donor (blood, serum, cDNA) are 
labeled with that number. No donor identifiable data is used to mark samples. All staff who have completed 
appropriate IRB and HIPAA training and are aware of the importance of maintaining donor confidentiality.

The risk of pneumococcal vaccination adverse side effects is minimal. In the rare event that an adverse 
reaction of greater magnitude then local reaction occurs, each volunteer is provided with a contact telephone 
number to reach research personnel who will see and potentially treat the adverse reaction as appropriate. 
The most common of these occasional adverse reactions consists of low grade fever, malaise and swollen 
lymph nodes, treatable with 2 days of prednisone. Adverse events associated with blood draws are rare and 
most commonly consist of prolonged bleeding treated with the application of local pressure. 
 
All adverse events will be monitored and recorded. Monitoring will take place at every visit by the study 
coordinator and the P.I.  
 
16.0 
Potential Benefits to Subjects or Others 
The benefits of participation in the study will consist of; 
1. Individual benefit: The protection offered by the vaccination protocol is thought to be beneficial 
to each participant although the degree of protection will vary from person to person. 
Pneumococcal vaccination is however recommended to all over 50 years of age and some studies 
show that the addition of PCV13 is beneficial and results in a better protection against 
pneumonia. The majority of the participants will receive PCV13 regardless of participation in 
the study as this is part of standard of care for individuals in groups 1-4. The vaccine costs in 
group 1-4 will be charged to the patient’s insurance as pneumococcal vaccination is standard of 
care. 
2. The ultimate goal of the study is to define the degree of protection against pneumococcal disease 
induced by the pneumococcal conjugate 13 valent vaccine in the aging RT population. Does the 
a The experimental data, i.e. antibody titers, opsonophagocytic titers,  B cell characteristics and 
single cell PCR results will be stored on laboratory computers and individual notebooks however 
this data will only be identified by numerical identifier. NO patient identifiers will be used on 
laboratory specimen or data at ANY time during the study. All experimental data will be 
confirmed by performing each experiment in duplicate.  All computers require ID specific log-
in. At no time is patient information associated with the data except at the time of analysis by 
the investigator if additional clinical information is needed. The results of the study will clarify 
and increase our understanding of both the aging and young RT recipients and particularly 
identify the potential cause of poor or deficient responses.  The results of these studies may 
benefit not only the 20% of the RT population over 65 years of age but also the younger RT 
recipients. 
 
The risks involved in this study are truly minimal and therefore based on the potential personal benefit to 
the enrolled volunteers and the overall knowledge gained, reasonable.
