Description: Adapted from WO2014/195881
Bordetella pertussis causes whooping cough, a highly contagious disease involving the respiratory tract, which is especially serious for infants and young children. Despite widespread immunization, in recent years the number of pertussis incidences has increased. The limited efficacy of currently used pertussis vaccines results from the fact that their components do not induce a complete immune response. Unlike tetanus and diphtheria diseases where all symptoms are caused exclusively by toxins, pertussis pathogenesis involves multiple virulence factors. Besides the secretory proteins of B. pertussis (e.g. pertussis toxin), surface molecules such as adhesins and endotoxin are involved in pathogenesis of pertussis. Therefore the pertussis vaccine needs to provide a functional immunity in the form of the toxin neutralization, blocking of bacterial adherence, opsonization, complement activation and bacterial killing. There is a need for a pertussis vaccine containing immunogenic, but completely inactivated components of B. pertussis.

This is a glycoconjugate of the complete dodecasaccharide derived from Bordetella pertussis LOS conjugated to a pertussis toxin which provides a vaccine component that is both immunogenic and non-toxic. It is a candidate for use in the pertussis vaccine composition as it constitutes a nontoxic and immunogenic combination of the two components of B. pertussis and thus generates optimal anti-pertussis response.
