Official title
A Randomized, Double Blind Phase 1b Trial to Examine the Influence of Antigenic Competition on the Immunogenicity of HIV-1 Gag/Pol: A Comparison of rAd5 Gag/Pol Env A/B/C to rAd5 Gag/Pol
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
HIV vaccines are designed to create an immune response to certain components of the HIV virus called peptides. Previous research indicates that one peptide, called Gag, may be particularly important for stimulating an immune response to HIV. Many vaccines being studied combine multiple peptides, but including other peptides may weaken the body's response to Gag. This study will test whether a vaccine that targets Gag and another peptide called Env is better than a vaccine without Env at causing an immune response to Gag.
