Comparative analysis of T cell-mediated proliferative responses in macaques immunized with live attenuated SIV strains. Data from a total of 22 vaccinated animals are shown, including data from animals presented in Fig. 1. Horizontal bars show median values, boxes indicate 75% confidence intervals, and error bars show 95% confidence intervals. The solid horizontal lines indicate the lower limit for significant SIV-specific stimulation indices. p55-specific proliferative responses in SIVΔnef-immunized animals are significantly greater compared with responses in animals infected with more attenuated SIV strains (P < 0.002, ANOVA).
