2. Immunocompetent community dwelling subjects between the ages of ages of 25-40 and 60-89 years.

Exclusion Criteria:

2. Receipt of any of the following products:

   1. Blood products within 3 months prior to study entry or expected receipt at any time after study entry*.
   2. Any live virus vaccines within 4 weeks prior to study entry or expected receipt within 4 weeks after study entry*.
   3. Any inactivated vaccine within 2 weeks or expected receipt within 2 weeks after study entry*.

3. Presence of co-morbidities or immunosuppressive states such as:

   • Chronic medical problems including (but not limited to) insulin dependent diabetes, severe heart disease, severe lung disease, severe liver disease, cerebrospinal fluid leaks, severe kidney disease, autoimmune diseases, severe gastrointestinal diseases and grade 4 hypertension per CTCAE criteria** .
   • Alcohol, drug abuse or psychiatric conditions that in the opinion of the investigator would preclude compliance with the trial or interpretation of safety or endpoint data.
   • Impaired immune function or known chronic infections including, but not limited, to known HIV, hepatitis B or C; organ transplant; immunosuppression due to cancer; current and/or expected receipt of chemotherapy, radiation therapy, steroids*** (i.e., more than 20 mg of prednisone given daily or on alternative days for 2 weeks or more in the past 90 days , or high dose inhaled corticosteroids**** or any other immunosuppressive therapies (including anti-TNF therapy), functional or anatomic asplenia and congenital immunodeficiency.

4. Conditions that could affect the safety of the volunteers such as:

   o Severe reactions to prior vaccinations.

   o An allergy to any component of the study vaccines (phenol, aluminum, CRM197 protein, succinic acid, Polysorbate 80).

   • History of Guillain-Barré syndrome.
   • History of bleeding disorders.
5. Volunteers with any acute illness* including, but not limited to, - fever (> 100.4 F [> 38 C], regardless of the route) within 3 days prior to study entry.
6. Volunteers with social conditions or occupational conditions or any condition that in the opinion of the investigator might interfere with compliance with the study and vaccine evaluation.

7. Pregnant or breast feeding or women expected to conceive within 30 days after vaccination *****

   • An individual who initially is excluded from study participation based on one or more of the time-limited exclusion criteria (e.g., acute illness, receipt or expected receipt of live or inactivated vaccines ) may be reconsidered for enrollment once the condition has resolved as long as the subject continues to meet all other entry criteria.

     • Grade 4 hypertension per CTCAE criteria is defined as Life threatening consequences(e.g., malignant hypertension, transient or permanent neurologic deficit, hypertensive crisis) urgent intervention indicated. ***Subjects receiving > 20 mg/day of prednisone or its equivalent daily or on alternate days for more than 2 weeks may enter the study after therapy has been discontinued for more than 3 months.

       • High dose ICS is defined as: > 960 mcg/day of beclomethasone dipropionate or equivalent ***** Women of child-bearing potential (not surgically sterile via tubal ligation, bilateral oophorectomy or hysterectomy or who are not postmenopausal for ≥1 year) must agree to practice adequate contraception that may include, but is not limited to, abstinence, monogamous relationship with vasectomized partner, barrier methods such as condoms, diaphragms, spermicides, intrauterine devices, and licensed hormonal methods for 30 days before and 30 days after receiving PPV23 or PCV13.
