Experimental strategies for the development of an immunocontraceptive vaccine for the European red fox, Vulpes vulpes.
The development of an immunocontraceptive vaccine to control fox populations in Australia would confer considerable advantages in controlling the long-term impact of this predator on native and endangered species. Studies are currently under way to identify sperm antigens that might be used in such a vaccine, and some of these studies are described. It is proposed that such a vaccine would be delivered orally in a bait, thereby stimulating a mucosal immune response to the foreign antigen(s). Such a vaccine requires a detailed understanding of reproductive-tract mucosal immunity in foxes, and selection of the most effective form of antigen delivery. Those under consideration include viral or bacterial vectors and microencapsulated antigens.
