Foxes developed serum neutralizing antibodies to rabies only after oral administration of an attenuated rabies vaccine, and not when a similar vaccine dose was introduced into the stomach. These results emphasize the need for a bait that assures delivery of a vaccine dose orally.
狐狸只有在口服减毒狂犬病疫苗后才会产生针对狂犬病的血清中和抗体，而当将相同剂量的疫苗引入胃部时则不会产生。这些结果强调了需要一种能确保口服疫苗剂量的诱饵。
