The clonal burst size of CD4 T cells is predicted to be less than that of CD8 T cells. In this study, we demonstrate that massive numbers of Ag-specific CD4 T cells respond during vaccination of mice with live attenuated Salmonella, reaching a peak frequency of approximately 50% of CD4 T cells. Salmonella-specific T cells persisted at high frequency for several weeks and could be detected in the memory population for months after infection. Surprisingly, the expansion of endogenous Salmonella-specific CD4 T cells prevented the persistence of adoptively transferred Salmonella-specific T cells in vivo, demonstrating interclonal competition for access to the memory compartment.
