MTBVAC
Candidate Overview
MTBVAC is an attenuated M. tuberculosis strain, by genetically engineering two independent unmarked stable deletion mutations in the virulence genes phoP and fadD26, based on clinical strain of the Euro-American lineage 4, the most widespread transmitted lineage between humans. MTBVAC includes RD1 absent in BCG, which contains 23% of the known human T-cell epitopes present in M. tuberculosis.
