摘要

The invention provides the use of an antigen which is a mucosally immunogenically active substance comprising the 50kD C fragment of tetanus toxin, an immunogenic fragment thereof, or a derivative thereof formed by amino acid deletion, substitution or insertion for the manufacture of a vaccine composition for administration to a mucosal surface to induce an immune response in the mucosal surface against tetanus infection. The vaccine composition preferably contains the P.69 outer membrane protein of B.pertussis, and B.pertussis filamentous haemaglutinin. The invention also provides vaccine compositions per se and a method of treating tetanus and optionally whooping cough using the vaccine compositions.
