TL;DR:
It is found that arrest of viral replication after challenge significantly correlates with a vaccine-induced response to IL-15 that includes modulation of T cell, inflammation, TLR signaling, and cell death programming, suggesting that RhCMV/SIV efficacy is not based on chance, but rather, results from a coordinated and sustained vaccine-mediated induction of innate and adaptive immune pathways.
