Erica Andersen-Nissen of Hutchinson Center Research Institute of South Africa and Gerhard Walzl of Stellenbosch University, both in South Africa, will perform bronchoalveolar lavage in volunteers receiving the BCG or MTBVAC vaccine intradermally in the HVTN 605 clinical trial to delineate vaccine-induced lung immune responses and identify correlates of protection. Lavage will be performed pre- and post-vaccination, and cells isolated from the lavage fluid will be analyzed for protein expression and by transcriptional profiling. They will compare the lung immune response they detect with the blood immune response identified in the large datasets available as part of the trial. Correlations between them could identify human blood biomarkers of lung T-cell responses that protect against TB. Such biomarkers will inform ongoing and future studies of immune correlates of efficacious TB vaccines.
