Brief Summary
This is a prospective, single-site, randomized, then open-label study designed to develop a detailed transcriptional and epigenetic profile of the immune response to pneumococcal vaccination with conjugated and non-conjugated polysaccharide vaccines in the senescent immune system of older adults. In this study, 40 healthy adults ages 60 and older that have never received pneumococcal vaccination, will be randomized in a 1:1 ratio to receive Prevnar-13 (Pfizer), a conjugated 13-valent vaccine or Pneumovax 23 (Merck), a non-conjugated 23-valent vaccine. Following randomized assignment of vaccine, the study will be open-label. Six (6) study visits will occur over about 70 days, with an optional 7th visit for participants to receive a second vaccination with the other pneumococcal vaccine one to two years after randomization. Participants will provide blood samples for transcriptional, epigenetic and biological analyses pre- and post-vaccination.

Outcome Measures
Primary Outcomes (2)
Pneumococcal-specific Antibody Responses
To vaccinate healthy older participants with pneumococcal vaccines, collect longitudinal blood samples and assess pneumococcal-specific antibody responses. The unit of measurement used is log2 titer defined as a measure to quantify the overall strength of responses using the sum of all serotype responses. Data shown below is from longitudinal study timepoints (pre and post) first pneumococcal vaccine. At study endpoint, Visit 7, a second pneumococcal vaccine was administered and no further sample collection visits were conducted as proposed in the study design.
70 days
Pneumococcal-specific Antibody Responses - Fold Change Post First Vaccination
Fold change between the baseline and post first vaccination titers was calculated for each pneumococcal vaccine cohort. Data shown below is from longitudinal study timepoints (pre and post) first pneumococcal vaccine. At study endpoint, Visit 7, a second pneumococcal vaccine was administered and no further sample collection visits were conducted as proposed in the study design.
70 days
Secondary Outcomes (2)
Number of Genes Upregulated Following Vaccination With PCV13 or PPSV23
10 days post first vaccination
Alterations to APCs, Tfh Cells or B Cells in Response to PCV13 and PPSV23
baseline and 10 days post first vaccination
Study Arms (2)
Prevnar 13
ACTIVE COMPARATORPrevnar 13 (Pneumococcal 13valent Conj Vaccine Diphtheria CRM197 Protein) will be administered at the single 0.5 ml dose, by intramuscular injection with routine clinical care.
Pneumovax 23
ACTIVE COMPARATORPneumovax 23 (Pneumococcal Vaccine Polyvalent) will be administered at the single 0.5ml dose, by intramuscular injection with routine clinical care.
Interventions
One to two years after receiving the randomly-assigned vaccination, participants may opt to receive administration of a second pneumococcal vaccine with Pneumovax 23
One to two years after receiving the randomly-assigned vaccination, participants may opt to receive administration of a second pneumococcal vaccine with Prevnar-13

- Access Criteria
- GEO open access Raw IPD controlled-access dbGaP per accession number above.
Participants will provide or decline consent within the ICF for sharing of their randomly recoded (new code that is different than the study code) genomic data in public and/or controlled access scientific databases. The study database will include a field for whether consent for genomic data sharing was provided or declined by the participant and if consent provided was for public and/or limited access databases. This information will be included in the dataset so that it can be provided to dbGAP (NIH database of Genotypes and Phenotypes) at the conclusion of the study to ensure that the wishes of the participant regarding use of their data and samples are respected. Raw IPD data is available through dbGAP (phs002361) due to patient privacy concerns. Genomic summary results and gene expression data are shared on GEO; accession numbers GSE247276 (Bulk) and GSE247277 (scRANSeq).
