摘要：
Vaccine compositions and methods are described for providing immunity to porcine circovirus type two (PCV2) genotypes including by administration of a recombinant PCV2 capsid polypeptide which comprises antigenic epitopes from the capsids of multiple PCV2 genotypes. In other embodiments a recombinant chimeric porcine circovirus is provides for use as a vaccine that combines the nonpathogenic backbone of porcine circovirus type 1 (PCV1) with the sequences encoding a PCV2 capsid polypeptide comprises antigenic epitopes from the capsids of multiple PCV2 genotypes.
