There is continued interest in developing novel vaccine strategies that induce establish optimal CD8+ cytotoxic T lymphocyte (CTL) memory for pathogens like the influenza A viruses (IAVs), where the recall of IAV-specific T cell immunity is able to protect against serologically distinct IAV infection. While it is well established that CD4+ T cell help is required for optimal CTL responses and the establishment of memory, when and how CD4+ T cell help contributes to determining the ideal memory phenotype remains unclear. We assessed the quality of IAV-specific CD8+ T cell memory established in the presence or absence of a concurrent CD4+ T cell response. We demonstrate that CD4+ T cell help a..View full abstract
