Wild boar can be immunized against African Swine Fever by a new vaccine delivered to the animals in their food, says new research. Published in Frontiers in Veterinary Science, it is the first report of a promising inoculation against this deadly disease, which is a worldwide threat to the swine industry. The study also provides evidence that this immunity can be passed on via contact with immunized individuals, but further studies are needed to examine exactly how this occurs, as well as the safety of repeated administration.
