RATIONALE: Vaccines made from peptides may help the body build an effective immune response. Incomplete Freund's adjuvant may stimulate the immune system in different ways and may help the vaccine work better. Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood. Giving vaccine therapy together with incomplete Freund's adjuvant and GM-CSF may be an effective treatment for patients with HIV.
