Study Summary

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.

Primary Outcome

for a minimum of 14 days following receipt of intramuscular injections and intranasal administrations of study products.
