One dose of UNISTRAIN® PRRS in gestating sows clinically protects against heterologous PRRS infection
After evidences for vaccine-induced protective immunity against non-homologous challenge (1, 2), in this study the heterologous efficacy of UNISTRAIN® PRRS was assessed but in naïve gestating sow model. Reproductive performance was the main parameter to claim the efficacy.
