A Clinical Trial to Evaluate the Safety and Immunogenicity of Glycan-trimmed HIV-1 Nanoparticle Vaccine (UVAX-1107), Followed by Homologous or Wild-type HIV-1 Nanoparticle Vaccine (UVAX-1197) Boost, Each Adjuvanted With 3M-052-AF + Alum in Adult Participants Without HIV

This is a phase 1, first-in-human (FIH) trial for the combination of UVAX-1107 and UVAX-1197, both adjuvanted with 3M-052-AF + Aluminum Hydroxide Suspension (Alum). This means it is the first time this combination of study products is being tested in people. The purpose of this study is to see if the study products are safe, if people are able to take them without becoming too uncomfortable, and how a person\'s immune system responds to them (a person\'s immune system protects them from infections and disease). Twenty-five volunteers without HIV and in overall good health will be enrolled and be in this study for a little over 1 year (56 weeks) of clinic visits (about 12 visits), with a follow-up contact 1 year after the final injection to check on their health. Study procedures will include blood draws, injections, and the collection of white blood cells and cells from their lymph nodes.
