Correlation of the IFN-γ ELISPOT response with susceptibility to infection. (A) Correlation of the number of inoculations required for infection and IFN-γ ELISPOTs after stimulation of PBMCs with AT2-inactivated SIV on the day of the first challenge. (B) Numbers of inoculations required for infection in macaques with more or less than 200 IFN-γ-secreting cells/106 PBMCs after stimulation with AT2-inactivated SIV at the time of the first challenge.
