Summary

This study tested an experimental HIV vaccine called Trimer 4571 in 32 adults with HIV who were already on suppressive antiretroviral therapy (ART). The goal was to see if the vaccine is safe and can help the immune system produce broadly neutralizing antibodies against HIV. Participants received either a low dose, a high dose, or a placebo. The study is complete, and results will show whether the vaccine is safe and stimulates an immune response.
