    “…An analogous regimen using HIV-1 subtype C virus demonstrated potent humoral and cellular responses in a Phase 1/2a trial and triggered a Phase 2b/3 double-blinded trial to assess the safety and efficacy of this regimen in South Africa. METHODS: We enrolled and randomized 5,404 healthy, HIV-uninfected 18-35-year olds at 14 sites to vaccine (2,704 participants) or placebo (2,700 participants) between 26 October 2016 and 21 June 2019. …”

    “…Subsequently, we evaluated the performance of the 11-gene signature in two external validation data sets viz, an independent cohort at the Glenfield Hospital, University Hospitals of Leicester NHS Trust, Leicester, UK (GSE107994 data set), and the Catalysis treatment response cohort (GSE89403 data set) from South Africa. The 11-gene signature validated and distinguished PTB from healthy and asymptomatic M. tuberculosis infected household controls in the GSE107994 data set, with an AUC of 0.95 (95% CI: 0.91–0.98) and 0.94 (95% CI: 0.89–0.98). …”
