Immunogenicity of an inactivated oil-emulsion canine distemper vaccine in African wild dogs

Abstract

The immunogenicity of an inactivated oil-emulsion vaccine against canine distemper virus was evaluated in nine captive African wild dogs (Lycaon pictus). Antibody levels were determined by, neutralization test in Vero cells. No significant local or systemic adverse reactions were observed in the animals. Virus neutralizing antibody levels >1:20 were detected, especially in animals that were vaccinated twice. The use of oil adjuvants is suggested as a good way to enhance the immune response to inactivated canine distemper vaccine. © Wildlife Disease Association 2004.
