Kinetics of antibody responses and protection against rabies were investigated after injection of a single dose of rabies DNA vaccine and compared to those induced by one or two injections of cell culture-derived vaccine in dogs issued from the common local breed and reared in experimental conditions. Rabies DNA vaccine administered intradermally by a jet injector in the inner face of the ear was by far more efficient in inducing long lasting high titers of virus neutralizing antibodies compared to cell culture vaccine Rabisin® administered either subcutaneously or intramuscularly. Four years after vaccine administration of either DNA or cell culture-derived rabies vaccines, full protection against a rabies peripheral challenge was achieved. Vaccine trials targeting dogs living in field conditions in Tunisia further established that rabies DNA-based vaccination induced a stronger induction of virus neutralizing antibodies compared to Rabisin®. This report shows for the first time that DNA vaccination could be more efficient under experimental or field conditions in large size mammals than the best commercially available cell culture-derived vaccine. This improvement will hopefully allow a better rabies control in developing countries by using a more efficient vaccination with fewer doses and targeting all categories of dogs.
