Vaccination with UNISTRAIN® PRRS significantly reduced the viral load in sera, the number of viraemic piglets and the length of the viraemia after a heterologous PRRS challenge with a pathogenic UK strain. Moreover, vaccination with UNISTRAIN® PRRS significantly reduced the amount of virus excreted, the number of piglets excreting virus and also the duration of viral excretion in saliva after challenge. Therefore, UNISTRAIN® PRRS is a useful tool to reduce the transmission of PRRS virus within and between pig populations.

The aim of this study was to demonstrate that vaccination of piglets with UNISTRAIN® PRRS better controls viraemia and reduces virus shedding after a heterologous PRRSV challenge.
