We examined the safety and immunogenicity of a human leukocyte antigen-based HIV envelope polyvalent synthetic peptide vaccine, C4-V3, alone and in combination with subcutaneous IL-12 in nine HIV-infected patients. Lymphocyte proliferative responses increased threefold or more to all four peptides at two consecutive post-immunization timepoints for four individuals. Three responders had received IL-12, suggesting a possible adjuvant effect of IL-12. Transient mild injection site reactions (7/9) and systemic symptoms (3/9) occurred.
