Abstract
Protective immunity against avian influenza virus was elicited in chickens by single-dose in ovo vaccination with a non-replicating human adenovirus vector encoding an H5N9 avian influenza virus hemagglutinin. Vaccinated chickens were protected against both H5N1 (89% hemagglutinin homology; 68% protection) and H5N2 (94% hemagglutinin homology; 100% protection) highly pathogenic avian influenza virus challenges. This vaccine can be mass-administered using available robotic in ovo injectors which provide a major advantage over current vaccination regimens. In addition, this class of adenovirus-vectored vaccines can be produced rapidly with improved safety since they do not contain any replication-competent adenoviruses. Furthermore, this mode of vaccination is compatible with epidemiological surveys of natural avian influenza virus infections.Entities:
