Description
Rhesus macaques (RMs) inoculated with live-attenuated Rev-Independent Nef simian immunodeficiency virus (Rev-Ind NefSIV) as adults or neonates controlled viremia to undetectable levels and showed no signs of immunodeficiency over 6-8 years of follow-up. We tested the capacity of this live-attenuated virus to protect RMs against pathogenic, heterologous SIVsmE660 challenges
