Our results suggest that some CD8 T cells induced by vaccination are more efficient than others at responding to a viral challenge. These findings have implications for future AIDS virus vaccine studies, which should consider the “fitness” of vaccine-induced T cells in order to generate robust responses in the face of virus exposure.
