摘要：
The present invention relates to a recombinant genetically attenuated Bordetella strain expressing a hybrid protein comprising the N-terminal fragment of filamentous haemagglutinin (FHA) and a heterologous epitope or antigenic protein or protein fragment, different from FHA, wherein the gene coding for the native FHA protein is inactivated. The Bordetella strain is preferably a Bordetella pertussis strain, but may also be another Bordetella species, such as Bordetella bronchiseptica, Bordetella parapertussis or Bordetella avium. The invention further provides a life attenuated vaccine for the treatment of a mucosal or systemic infectious disease comprising a Bordetella strain as defined above intended to elicit a immune response against pathogens responsible for systemic or mucosal infections, including of the upper or lower respiratory tract. The present invention also relates to a method for prophylaxis of an infectious disease in a mammal, comprising administering to said mammal an effective amount of a vaccine comprising in a suitable vehicle a recombinant attenuated Bordetella strain expressing a fusion protein comprising the N-terminal fragment of filamentous haemagglutinin (FHA) and a heterologous epitome or antigenic protein or protein fragment, different from FHA, wherein the gene coding for the native FHA protein is inactivated.
