Trial Summary

What is the purpose of this trial?

The goal of this clinical trial is to test 16055 NFL delta Gly4 Env protein trimer and Trimer 4571 combined with 3M-052-AF + Alum adjuvant and Ad4-Env145NFL viral particles as heterologous prime-boost regimens in adult participants without HIV. The main question\[s\] it aims to answer are: * Are these vaccine regimens safe and well tolerated? * Are the prime-boost vaccine regimens that include Ad4-Env145NFL and Trimer 4571 as heterologous boosts going contribute to the development of B-cell and antibody responses? Participants will attend scheduled study visits to receive their vaccine and will record symptoms on a daily eDiary.
