Summary and Implications

Vaccination of swine with an alphavirus-derived replicon particle vaccine stimulates a non-specific immune response. This effect was seen when animals were challenged with PRRSV at 24 hours post-vaccination. Animals that received vaccine had reduced viremia as measured by quantitative RT-PCR when compared to placebo. These results highlight the potential of replicon particle vaccines to induce robust immune responses in swine.
