Brief Summary
To evaluate the safety and immunogenicity of an accelerated schedule of recombinant canarypox vaccine ALVAC-HIV MN120TMG (vCP205) versus control followed by boost with rgp120/HIV-1 SF2 vaccine in HIV-negative volunteers. Frequent injections of ALVAC-HIV vCP205 may result in more rapid induction of cytotoxic T-lymphocytes. This trial will evaluate whether an accelerated vaccination schedule can produce immunological responses comparable to those obtained in other trials of ALVAC-HIV vCP205.

Eligibility Criteria
You may qualify if:
- Volunteers must have:
- Normal history and physical exam.
- Negative ELISA and Western blot 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:
- Volunteers 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.
- Occupational responsibilities that preclude 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.
- Occupational exposure to birds.
- Volunteers 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.
