The decoy epitope (169-180aa) of Procine circovirus type 2 (PCV2) capsid protein is associated with porcine circovirusassociated diseases (PCVAD). Co-infection of pigs with PCV2 and porcine reproductive and respiratory syndrome virus (PRRSV) causes postweaning multisystemic wasting syndrome (PMWS). In the present study, PCV virus-like particles (VLPs) were constructed by replacing the decoy epitope of PCV2 capsid with PRRSV GP3 epitope (61-72aa), PRRSV GP5 epitope (187-200aa) and PRRSV GP3 epitope conjugated with GP5 epitope. The three chimeric PCV2 VLPs were produced using the baculovirus expression system, tested by western blotting and detected the ability to induce protective antibody responses in mice. Three chimeric Capsid proteins induced strong humoral and cellular immune responses in mice, and may provied an effective vaccine strategy for protection against PCV2 and PRRS
