Our goal is to validate and improve modified live-virus (MLV) PRRSV vaccine candidates that express replication-competent interferons (IFNs).
The objective will be met using the following approaches: 1) Examine the kinetics of the incorporated IFN expression in vivo, and its effect in potentiation of antiviral immunity. 2) Implement a reverse-genetic platform to efficiently rescue and attenuate field isolates as vaccine backbones for improving vaccine efficacy and safety. 3) Optimize adjuvant regulation for better growth performance of vaccinated piglets.
