The immunogenic and protective properties of acellular pertussis vaccines, prepared on the basis of B. pertussis multicomponent protective complex and the preparation containing only pertussis toxin, were studied. The study revealed that multicomponent preparations containing pertussis toxin (PT), filamentous hemagglutinin, agglutinogens, pertactin and adenylate cyclase possessed more pronounced immunobiological and protective properties in comparison with the monovalent preparation of PT, which was indicative of the expediency of developing acellular pertussis vaccines on the basis of the polyvalent protective complex as minor protective antigens seemed to enhance the protective action of pertussis toxoid, the main protective antigen.
