Ad5-105K
The Inhaled Tuberculosis Vaccine (Adenovirus Type 5 Vector) developed by CanSino Biologics Inc. is a non-replicating viral-vectored vaccine intended for administration via nebulized inhalation by mouth. It is designed to induce both local mucosal immunity in the respiratory tract and systemic immune responses against Mycobacterium tuberculosis (Mtb). The adenovirus type 5 (Ad5) backbone functions as…

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.

Tri:ChAd:TB is built on the chimpanzee adenovirus serotype 68 vector, expressing Ag85A, TB10.4, and RpfB. These antigens spanning distinct M.tb life-cycle stages. Ag85A wanes after acute infection, whereas TB10.4 remains highly expressed. RpfB is upregulated during dormancy and resuscitation. This vaccine is formulated for respiratory mucosal delivery.
Read MoreSeV986A
Our group utilizes an replication-defective Sendai virus (SeV) as TB vaccine vector, and constructed SeV85AB and SeV986A vaccine. SeV986A expressed a fusion of acute- and latency-stage Mtb antigens (4 antigens). In murine models, it serves as a potent BCG-booster, significantly reducing bacterial burden in both active and latent infection challenges.
