Some of these epitope-specific CD8 T cells emerge in the weeks and months following infection and rapidly select for sequence variants, whereas other CD8 T cell responses develop during the chronic infection phase and rarely select for sequence variants. In this study, we tested the hypothesis that acute-phase CD8 T cell responses that do not rapidly select for escape variants are unable to control viral replication\n            <jats:italic>in vivo<\/jats:italic>\n            as well as those that do rapidly select for escape variants. We created a derivative of live attenuated SIV (SIVmac239\u0394nef) in which we ablated five epitopes that elicit early CD8 T cell responses and rapidly accumulate sequence variants in SIVmac239-infected Mauritian cynomolgus macaques (MCMs) that are homozygous for the M3 major histocompatibility complex (MHC) haplotype. This live attenuated SIV variant was called m3KO\u0394nef. Viremia was significantly higher in M3 homozygous MCMs infected with m3KO\u0394nef than in either MHC-mismatched MCMs infected with m3KO\u0394nef or MCMs infected with SIVmac239\u0394nef. Three CD8 T cell responses, including two that do not rapidly select for escape variants, predominated during early m3KO\u0394nef infection in the M3 homozygous MCMs, but these animals were unable to control viral replication. These results provide evidence that acute-phase CD8 T cell responses that have the potential to rapidly select for escape variants in the early phase of infection are needed to establish viral control\n            <jats:italic>in vivo<\/jats:italic>\n            .\n
