| abstract |
A replication defective recombinant adenovirus is provided which contains a complete deletion of its E1 gene and at least a partial deletion of its E3 gene, said virus containing in the site of the E1 deletion a sequence comprising a non-adenovirus promoter directing the replication and expression of DNA encoding a heterologous protein from a disease-causing agent, which, when administered to a mammal in said recombinant virus, elicits a substantially complete protective immune response against the agent. Pharmaceutical and veterinary products containing the recombinant adenovirus are provided. |
