title: A chimpanzee-origin adenovirus vector expressing the rabies virus glycoprotein as an oral vaccine against inhalation infection with rabies virus.
abstract: Rabies has the highest fatality rate of all human viral infections and the virus could potentially be disseminated through aerosols. Currently licensed vaccines to rabies virus are highly effective but it is unknown if they would provide reliable protection to rabies virus transmitted through inhalation, which allows rapid access to the central nervous system upon entering olfactory nerve endings. Here we describe preclinical data with a novel vaccine to rabies virus based on a recombinant replication-defective chimpanzee-origin adenovirus vector expressing the glycoprotein of the Evelyn Rokitniki Abelseth strain of rabies virus. This vaccine, termed AdC68rab.gp, induces sustained central and mucosal antibody responses to rabies virus after oral application and provides complete protection against rabies virus acquired through inhalation even if given at a moderate dose.
