8. All sexually active males (unless anatomically sterile or in a monogamous relationship with a female partner who uses a documented non-barrier method of birth control) must be willing to use an effective method of contraception (such as consistent condom use) from the day of first vaccination until at least 4 months after the last vaccination ;
9. Willing to forgo donations of blood, or any other tissues during the study and, for those who test HIV-positive due to vaccine-induced antibodies, until the anti-HIV antibody titers become undetectable;
10. Women, who are not heterosexually active at screening, must agree to utilize an effective method of contraception if they become hetero-sexually active, as outlined above.

Exclusion Criteria:

Confirmed HIV-1 or HIV-2 infection; any clinically relevant abnormality on history or examination including history of immunodeficiency or autoimmune disease; use of systemic corticosteroids (the use of topical, nasal or inhaled steroids is permitted), immunosuppressive, anticancer, anti-tuberculosis or other medications considered significant by the investigator within the previous 6 months;
2. The following exceptions are permitted and will not exclude study participation: use of corticosteroid nasal spray for rhinitis, topical corticosteroids for an acute uncomplicated dermatitis; or a short course (duration of 10 days or less, or a single injection) of corticosteroid for a non-chronic condition (based on investigator clinical judgment) at least 2 weeks prior to enrollment in this study;
3. Any clinically significant acute or chronic medical condition that is considered progressive or in the opinion of the investigator makes the volunteer unsuitable for participation in the study;
4. Reported risky behavior for HIV infection within 12 months prior to vaccination
5. If female, pregnant or planning a pregnancy during the period of enrollment until 4 months after the last study vaccination; or lactating;
6. Bleeding disorder that was diagnosed by a physician (e.g., clotting factor deficiency, coagulopathy or platelet disorder that requires special precautions) (Note: A volunteer who states that he or she has easy bruising or bleeding, but does not have a formal diagnosis and has had IM vaccine administrations and blood draws without any adverse experience, is eligible);
7. Infectious disease: chronic hepatitis B infection (HbsAg-positive), current hepatitis C infection (HCV Ab positive and HCV RNA positive) treatment for chronic hepatitis C infection in the past year, or active syphilis (positive RPR confirmed by TPHA);
8. Receipt of live attenuated vaccine within the previous 30 days or planned receipt within 30 days after vaccination with Investigational Product; or receipt of other vaccine within the previous 14 days or planned receipt within 14 days after vaccination with Investigational Product. (Exception is live attenuated influenza vaccine within 14 days);
9. History of splenectomy;
10. Receipt of blood transfusion or blood-derived products within the previous 3 months;

11. Any of the following abnormal laboratory parameters listed below:

    Hematology

    • Hematocrit: \<35%
    • Absolute Neutrophil Count (ANC): ≤1,000/mm3
    • Absolute Lymphocyte Count (ALC): ≤650/mm3
    • Platelets: \<125,000 cells/mm3 Chemistry
    • Creatinine >1.1 x upper limit of normal (ULN)
    • ALT >1.25 x ULN
    • AST >1.25 x ULN Urinalysis
    • Clinically significant abnormal dipstick confirmed by microscopy:
    • Protein = 1+ or more
    • Blood = 2+ or more (not due to menses)
12. Participation in another clinical trial of an Investigational Product currently, within the previous 3 months or expected participation during this study (Concurrent participation in an observational trial not requiring any blood or tissue sample collection is not an exclusion);
13. Prior receipt of another investigational HIV vaccine candidate (Note: receipt of placebo in a previous HIV vaccine trial will not exclude a volunteer from participation if documentation is available and the Medical Monitor gives approval);
14. History of severe local or systemic reactogenicity to vaccines (e.g., anaphylaxis, respiratory difficulties, angioedema, injection site necrosis or ulceration);
15. Psychiatric condition that compromises safety of the volunteer and precludes compliance with the protocol. Specifically excluded are persons with psychoses within the past 3 years (prior to screening), ongoing risk for suicide, or history of suicide attempt or gesture within the past 3 years;
