- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: PREVENTION
- Time Perspective: None
- Masking: None
- Phase: PHASE2
- Number of Arms: 6.0

Eligibility Criteria:
Inclusion Criteria:~1. Male or female adults 55 through 74 years of age at the time of enrollment who are able to provide informed consent. 2. For the pneumococcal vaccine-naïve group (Group I), no pneumococcal vaccine received prior to enrollment, as documented by participant report and review of available vaccine records. For the previously vaccinated group (Group II), documented vaccination with exactly one dose of PPSV23 administered \>/=3 and \</=7 years prior to enrollment and no other lifetime doses of PPSV23. (History of receipt or non-receipt of a pneumococcal vaccine may be presumptively ascertained by participant report but must be confirmed by review of primary source information, including but not limited to medical records, primary care or other provider report, and health department records. Medical records should be reviewed and/or primary care or other providers queried to identify pneumococcal vaccinations administered for a period of not less than 10 years prior to enrollment.) 3. Determined by medical history, targeted physical examination (if indicated), and clinical judgment to be eligible for the study. Subjects with preexisting stable disease, defined as disease not requiring significant change in therapy (A change in dose or therapy within a category (e.g., change from one nonsteroidal anti-inflammatory drug to another) is allowed. A change to a new therapy category (e.g. surgery or addition of a new pharmacological class) is only allowed if it is not caused by worsening disease.) or hospitalization for worsening disease 12 weeks prior to enrollment, are eligible. 4. Agree not to receive a live virus vaccine (for example, zoster vaccine) before the Day 28 (Visit 03) blood specimen collection and not to receive an inactivated vaccine (for example, inactivated influenza vaccine) within 14 days after enrollment. 5. The subject is able to understand and comply with the planned study procedures including being available for all study visits. 6. The subject has provided informed consent prior to any study procedures.~Exclusion Criteria:~1. Receipt of any PCV or investigational pneumococcal vaccine prior to enrollment. 2. Receipt of any inactivated vaccine within 14 days prior to enrollment or receipt of any live vaccine within 30 days prior to enrollment. 3. Receipt of an allergy desensitization injection within 14 days prior to enrollment or planned receipt of an allergy desensitization injection within 7 days following enrollment. 4. Receipt of a diphtheria toxoid containing vaccine (for example, tetanus and diphtheria toxoid \[Td\] or tetanus and diphtheria toxoid and acellular pertussis \[TdaP\] vaccine) within six months prior to enrollment. 5. Known or suspected immunodeficiency, receipt of cancer chemotherapy or radiation therapy within the preceding 36 months, or receiving treatment with immunosuppressive therapy, including systemic corticosteroids, e.g., for cancer, HIV or autoimmune disease. If any systemic (oral, parenteral) corticosteroids have been administered for treatment of acute illness within 30 days of vaccination, and any long term use (\>2 weeks) in the 30 through 59 days before vaccination should be excluded. (Topical, intranasal, and inhaled corticosteroids are allowed.) 6. Serious chronic disorders including active or metastatic malignancy, hematologic malignancy, severe chronic obstructive pulmonary disease or clinically significant congestive heart failure, requirement for supplemental oxygen, end stage renal disease with or without dialysis, clinically unstable cardiac disease, or any other disorder that in the opinion of the investigator precludes the subject's participation. 7. Known HIV, hepatitis B or hepatitis C infection. 8. Residence in a nursing home or other skilled nursing facility or requirement for skilled nursing care. An ambulatory subject who does not require skilled nursing care and is a resident of a retirement home or community is eligible for the trial. 9. Inability to provide informed consent or complete study activities, for example, due to dementia or other impairment. 10. Poor or missing eyesight, requiring third party support to read. 11. Receipt of any blood products, including immunoglobulin, within three months prior to enrollment. 12. Heart rate less than 40 bpm or greater than 120 bpm as measured at the enrollment visit and prior to vaccination. 13. Systolic blood pressure less than 90 mm Hg or greater than 170 mm Hg as measured at the enrollment visit and prior to vaccination. 14. Diastolic blood pressure greater than 110 mm Hg as measured at the enrollment visit and prior to vaccination. 15. For Group I, unable to receive a vaccination in the deltoid muscle of the right arm and unable to receive a vaccination in the deltoid muscle of the left arm because of insufficient muscle mass, need to avoid injections due to prior lymph node dissection or radiation, or other factor. For Group II, unable to receive a vaccination in the deltoid muscle of one or both arms because of insufficient muscle mass, need to avoid injections due to prior lymph node dissection or radiation, or other factor. 16. Currently on anticoagulant therapy (for example, warfarin, heparin \[IV or SQ\], or dabigatran) or a history of bleeding diathesis that would contraindicate intramuscular injection. (Aspirin, clopidogrel, dipyridamole, and nonsteroidal anti-inflammatory agents are allowed). 17. Known clinically significant allergic reaction to prior pneumococcal vaccination (for Group II participants) or to a component of PCV13 vaccine (PCV13 is latex free). 18. Current known abuse of alcohol or drug addiction that in the opinion of the Investigator may interfere with the subject's ability to comply with trial procedures. 19. Rec eipt of any other investigational vaccine or agent within one month before enrollment or intent to receive any other investigational vaccine or agent prior to the conclusion of the study. 20. Any medical condition that would, in the opinion of the investigator, place the participant at an unacceptable risk of an adverse event or interfere with the evaluation of the study objectives.
