Unlike previous studies characterizing virus-specific CD8+ T cell responses to HIV, Epstein-Barr virus, dengue virus, or adenovirus9,17,19,27, we did not detect any A2:LLWNGPMAV-specific T cells in either the blood or spleen over the course of infection, indicating that YFV-17D-specific cells are poorly primed in NRG-A2-HIS mice (Supplementary Figure 1d). The gene discussed is CD8A; the disease is infection.
