The porcine reproductive and respiratory syndrome virus (PRRSV) continues to be a threat, exerting significant economic effects on the swine industry worldwide. However, none of the current commercially available vaccines can completely prevent respiratory infection, trans-placental transmission, pig-to-pig transmission of the virus, or maintain immune protection in sows. This study provides information on PRRSV and a review of available options for PRRS control strategies based on its pathogenic characteristics, immune properties, and biological characteristics.
