“Producers and veterinarians now can have even more confidence in using the vaccine.” PRRSGard is a 1.0 millilitre, single-dose recombinant chimeric vaccine for Porcine Reproductive and Respiratory Syndrome (PRRSV). It features:

  • An attenuated, lineage 1 PRRSV strain as a vaccine backbone
  • A virulent, contemporary lineage 1 PRRSV field isolate, MN 184
  • A non-encoding RNA sequence is inserted into the genome. This unique genetic marker allows diagnostic assay differentiation from “wild-type” virus strains.

Trials show that PRRSGard promotes broad cross-strain immunity, reduced lung lesions and viremia, a low vaccine virus shed and spread following a challenge. It has been shown to reduce performance loss from pneumonia associated with PRRSV in growing pigs.
