Effect of influenza A virus sow vaccination on infection in pigs at weaning: A prospective longitudinal study

Dr. Chamba Pardo and colleagues from the University of Minnesota share results of the implementation of sow vaccination to control influenza infections in pigs at weaning through a special issue article published in Transboundary and Emerging Diseases.

Highlights

  • Sow vaccination against IAV was effective at reducing the number of infected groups of pigs at weaning, and the number of positive nasal swab pools within a group.
  • Both prefarrow or whole herd vaccination protocols, and use of commercial or autogenous inactivated vaccines, yielded significant and similar reduction of IAV infections in pigs at weaning.
  • Sow vaccination can help control IAV infections in pigs at weaning and, thus, minimize transmission to growing pigs and other farms.
