Brief Summary
To evaluate, in HIV-negative volunteers, the safety and immunogenicity of ALVAC-HIV MN120TMGNP (vCP300) followed by or combined with boosting using rgp120/HIV-1SF2. To compare ALVAC-HIV vCP300 with ALVAC-RG rabies glycoprotein (vCP65) as a control. To evaluate an accelerated immunization schedule at 0, 1, 3, and 6 months versus 0, 1, 6, and 9 months. The combination of a live recombinant primer followed by a subunit boost has the potential to induce not only cytotoxic T lymphocytes but also neutralizing antibody.

Eligibility Criteria
You may qualify if:
- Volunteers must have:
- Normal history and physical exam.
- ELISA and Western blot negative for HIV.
- CD4 count \>= 400 cells/mm3.
- Normal urine dipstick with esterase and nitrite.
- Lower risk sexual behavior.
You may not qualify if:
- Co-existing Condition:
- Subjects with the following symptoms or conditions are excluded:
- Positive hepatitis B surface antigen.
- Medical or psychiatric condition (such as recent suicidal ideation or present psychosis) that precludes compliance.
- Active syphilis. NOTE: Subjects with serology documented to be a false positive or due to a remote (\> 6 months) treated infection are eligible.
- Active tuberculosis. NOTE: Subjects with a positive PPD and a normal chest x-ray showing no evidence of TB and not requiring isoniazid therapy are eligible.
- Allergy to egg products or neomycin.
- Subjects with the following prior conditions are excluded:
- History of immunodeficiency, chronic illness, autoimmune disease, or use of immunosuppressive medications.
- History of anaphylaxis or other serious adverse reactions to vaccines.
- Prior immunization against rabies.
- History of serious allergic reaction to any substance, requiring hospitalization or emergent medical care (e.g., Stevens-Johnson syndrome, bronchospasm, or hypotension).
- Prior psychiatric condition (such as history of suicide attempts or past psychosis) that precludes compliance.
- History of cancer unless there has been surgical excision that is considered to have achieved cure.
- Prior Medication:
