PG - 5960-6 LID - 10.1016/j.vaccine.2010.07.002 [doi] AB - The efficacies of commercial porcine circovirus type 2 (PCV2) vaccines and a live PCV1-2a chimeric vaccine were compared in conventional, PCV2-positive piglets using a PCV2-porcine reproductive and respiratory syndrome virus (PRRSV)-porcine parvovirus (PPV) coinfection challenge model. Seventy-three, 2-week-old pigs were randomized into seven groups including five vaccinated and two control groups. Pigs in the vaccinated groups were vaccinated at 3 weeks (one dose) or at 3 and 6 weeks (two dose) of age. All vaccine regimens tested were effective in reducing naturally occurring PCV2 viremia at 16 weeks of age and after PCV2 challenge, demonstrating the capability of the products to induce a lasting protective immunity despite the presence of PCV2 viremia at the time of vaccination.
