Inclusion Criteria

- HIV negative.

- Acceptable methods of contraception.
Minimum age
18 Years
Maximum age
55 Years
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
Exclusion Criteria

- Identifiable risk behavior for HIV infection, including: sexual partners of HIV
positive people, sexual intercourse with a partner of unknown HIV status if that
partner is reported to be at higher risk for HIV infection, gay men reporting any
unprotected anal intercourse with partners of unknown status in the 12 months
preceding study entry, individuals diagnosed with a sexually transmissible infection
(STI) in the 12 months preceding entry that may have been acquired through anal or
vaginal intercourse, individuals reporting sharing of injecting equipment in the last
12 months.

- HIV candidate vaccines in a previous HIV vaccine trial.

- Live attenuated vaccines within 60 days prior to entering the study. Whole killed,
toxoid, or sub-unit vaccines (e.g., influenza, pneumococcal, tetanus, and hepatitis B)
are not exclusionary within 4 weeks prior to the scheduled experimental HIV vaccines.

- Hypersensitivity to egg products or a known history of anaphylaxis or any other
serious adverse reactions to vaccination.

- History of serious allergic reaction requiring hospitalization or emergency medical
care (e.g., Stevens-Johnson syndrome, bronchospasm, or hypotension) to any substance.

- Significant illness requiring immunomodulatory or cytotoxic therapy.

- History of cancer unless there is evidence of surgical excision followed by a
sufficient observation period to give a reasonable assurance of cure.

- Blood products or immunoglobulins within 6 months prior to entering the study.

- Experimental or investigational agents within 30 days prior to entering the study.

- Recreational and/or therapeutic drug use that might compromise the study participant's
safety.

- Medical or psychiatric condition or occupational responsibilities that preclude
compliance with the protocol.

- Pregnant or lactating women.

This study will examine the safety and immune response to a two-part HIV vaccine. Healthy
volunteers who are at low risk of HIV infection will receive either active vaccine or a
placebo.
