Brief description of study

The primary hypotheses are that the vaccine regimens will be safe and well tolerated and the prime-boost vaccine regimens that include Ad4-Env145NFL and Trimer 4571 as heterologous boosts will contribute to the development of B-cell and antibody (Ab) responses directed to the cross-conserved CD4 binding site (CD4bs) and gp120/gp41 fusion peptide interface or other regions with the potential to elicit heterologous neutralization.
