MULTIVALENT ANTIHELMINTHIC VACCINE

摘要

A multivalent anthelmintic vaccine targets both hookworm and schistosomiasis. The vaccine includes, at a minimum, a recombinant third-stage larval hookworm antigen, a recombinant adult stage hookworm antigen, and a recombinant schistosome antigen. Preferably, the hookworm antigens are Necator americanus antigens, although antigens from other hookworm species (e.g. Ancylostoma duodenale) may also be employed. The schistosome antigen is preferably a Schistosoma mansoni or a Schistosoma haematobium antigen although antigens from other schistosome species (e.g. Schistosoma japonicum) may also be employed. In some cases full or partial sequences of shistosome antigens may be fused with full or partial sequences of hookworm {Necator americanus) to produce recombinant chimeric antigens.
