text_1: Lice attenuated SIV vaccines induce a stronger antigen-specific T cell response in lymph node cells.
text_2: Here we show that the degree of LAV-mediated protection against intravenous wild-type SIVmac239 challenge strongly correlates with the magnitude and function of SIV-specific, effector-differentiated T cells in the lymph node but not with the responses of such T cells in the blood or with other cellular, humoral and innate immune parameters.
