A selection of previously identified protective Mycobacterium tuberculosis DNA vaccines were re-formulated as proteins and administered with a Th1-inducing adjuvant to help stimulate the relevant immune responses necessary for protection. One candidate (Rv1806-1807) induced protection in the guinea pig aerosol infection model 30 days post-challenge on the basis of reducing the bacterial burden of M. tuberculosis in the lungs (Vipond et al., 2006).
