A replication-defective human adenovirus recombinant serves as a highly efficacious vaccine carrier

In this manuscript, an E1 and E3 deleted adenoviral recombinant expressing the rabies virus glycoprotein (G protein) under the control of the cytomegalovirus early promoter was tested for induction of a rabies virus-specific immune response in mice. The construct was found to induce neutralizing antibodies and cytolytic T cells to rabies virus. Mice vaccinated with the adenoviral construct either by the systemic route or by application into the airways were protected against a subsequent infection with a virulent strain of rabies virus. The efficacy of the replication-defective construct was far superior to that of a well-characterized vaccinia rabies glycoprotein recombinant. (C) 1996 Academic Press, Inc.
