Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Volunteers are randomized to one of seven groups to receive immunizations with either ALVAC-HIV vCP300 or ALVAC-RG vCP65 (control), plus simultaneous or sequential boosting with rgp120/HIV-1SF2 or placebo. Immunizations are given at 0, 1, 6, and 9 months or 0, 1, 3, and 6 months. Volunteers are followed for at least 24 months.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* 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.
Exclusion Criteria
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:
Excluded:
* Live attenuated vaccines within 60 days prior to study entry. NOTE: Medically indicated killed or subunit vaccines (e.g., influenza, pneumococcal) do not exclude if administered at least 2 weeks from HIV immunizations.
* Experimental agents within 30 days prior to study entry.
* Prior HIV vaccines.
* Prior rabies immunization.
Prior Treatment:
Excluded:
* Blood products or immunoglobulin within 6 months prior to study entry. Identifiable high-risk behavior for HIV infection, such as
* injection drug use within past 12 months.
* higher or intermediate risk sexual behavior.
