TBvac-1, TBvac-2, TBvac-10
Candidate Overview
TBvac-1, TBvac-2, and TBvac-10 use a recombinant tri-segmented Pichinde virus (PICV) vector (rP18tri) to express M. tuberculosis antigens. TBvac-1 and TBvac-2 encode Ag85B, EsxA/ESAT-6, and EsxH/TB10.4, with antigen locations swapped between S1 and S2 segments. TBvac-10 encodes Ag85B, EsxH/TB10.4, RpfA, and Rv1733c. Vaccine stocks are produced in BHK-21 cells from plaque purified virus.
