摘要： Disclosed is a vaccine for non-human animals, which vaccine enables effective immune induction in non-human animals such as livestock or poultry. The vaccine for non-human animals of the present invention comprises liposomes each comprising an antigen molecule(s) bound to the surface thereof, the antigen molecule(s) being derived from a pathogen infectious to the non-human animals. The non-human animals are, for example, livestock or poultry. One most preferred example of the vaccine according to the present invention is an infectious bronchitis virus (IBV) vaccine, which is effective against various isolated IBV strains, and which is expected to be sufficiently applicable even to cases where a mutant strain appeared. Another preferred example of the vaccine according to the present invention is a PRRSV vaccine, which was confirmed to have an effect that reduces fever, lung lesion development, and the like caused by the infection. The present invention enables development of liposome vaccines effective for prevention of infections caused by various non-human animal pathogens including PRRSV as well as IBV.
