Similar observations were made about the hyena dog, which was in 1989 threatened with extinction. Scientists vaccinated individual animals to protect them against rabies but more than a dozen packs then died within a year – of rabies. This happened even in areas where rabies had never been seen before. When researchers tried using a non-infectious form of the pathogen (to prevent the deaths of the remaining animals) all members of seven packs of dogs disappeared. And yet the rabies vaccine is now compulsory in many parts of the world. Is it not possible that it is the vaccine which is keeping this disease alive?"---- Dr Vernon Coleman MB
