Project description:The RV144 clinical trial evaluated the efficacy of a vaccine regimen that included ALVAC-HIV prime and AIDSVAX boost in preventing HIV-1 acquisition. The vaccine reduced the risk of HIV-1 acquisition by 31.2%; however the mechanisms that led to the protection induced by this vaccine remain poorly understood. Our objectives were to identify transcriptional correlates and mechanisms that could explain the reduced acquisition conferred by the vaccine. We assessed the transcriptomic profile of HIV Env stimulated peripheral blood mononuclear cells collected from 223 participants two weeks after vaccination and from 40 placebo recipients.
