Abstract
Vaccine compositions which are protective against circovirus infections, including porcine circovirus and psittacine beak and feather disease virus, in animals, comprising a nucleic acid vector comprising a eukaryotic cis-acting transcription/translation regulatory sequence functionally linked to a nucleic acid encoding an animal circovirus polypeptide, wherein the nucleic acid lacks a viral origin of replication are disclosed. Nucleic acid vectors for the transient expression of one or more circovirus polypeptides in a eukaryotic cell comprising a nucleic acid vector comprising a eukaryotic cis-acting transcription/translation regulatory sequence functionally linked to the nucleic acids of the invention are described. Methods of preventing a circovirus-associated disease in an animal comprising administering to the animal a nucleic acid vector comprising a eukaryotic cis-acting transcription/translation regulatory sequence functionally linked to a nucleic acid encoding an animal circovirus polypeptide, wherein the nucleic acid lacks a viral origin of replication are also described. Methods of preventing a circovirus-associated disease in an animal comprising administering to the a…
