Targeted lymph node immunization involves vaccine injection into the subcutaneous tissue near a lymph node. This strategy has proven effective in the simian immunodeficiency virus (SIV)/rhesus macaque model. The iliac and inguinal lymph nodes in the groin are the primary draining lymph nodes of the genitourinary and rectal tracts. This study will evaluate and compare the safety and immunogenicity of ALVAC-HIV (vCP205) when administered subcutaneously in the groin and intramuscularly in the deltoid region. ALVAC-HIV (vCP205) is a canarypox virus vector vaccine expressing portions of the gp120, Gag, and Pol genes.
