POLB 003 – Melioidosis Vaccine Candidate

Through an extensive characterisation of the protein structures present on the bacteria’s surface, the team at University College Dublin identified a homologue of the common OmpW bacterial antigen specific to this strain, called BpOmpW. Preclinical studies using this antigen showed significant survival benefit when challenged with the bacteria. Similarly, so-called correlates of protection, which provide an indication of the protection status of a subject, were much improved including increased IFN-γ production and an enhanced T-Cell response profile, both of which have a proven role in protection against Melioidosis.
