Rabies continues to be a serious problem in both developed and developing nations due to the reservoir of rabies virus in wildlife vectors. The control and worldwide eradication of rabies depends on the development of safe, effective, and economical vaccines that might be used in preexposure vaccination programs for humans and animals. To this end an infectious human adenovirus type 5 recombinant virus that contains the rabies glycoprotein gene, and which may serve as the prototype for a new class of vaccines against rabies, was constructed and tested. This recombinant, when administered by either the parenteral or oronasal route, was highly effective in eliciting good levels of rabies-neutralizing antibodies in the sera of dogs and mice. Mice immunized by the recombinant virus were protected from lethal intracerebral challenge with rabies virus.
