Porcine reproductive and respiratory syndrome virus (PRRSV) causes respiratory disease in nursery and grow-finisher pigs and reproductive failure in sows and boars. PRRSV-infected pigs usually suffer from poor growth performance and are highly susceptible to co- or secondary bacterial and other viral infections.
PRRSV was first isolated in Korea in 1994 and all PRRSV isolates corresponded to the Type II until 2000, Type I PRRSV has recently emerged in Korea.
In this study we evaluate the efficacy of Ingelvac® PRRS MLV (Type II PRRSV based vaccine) piglet vaccination in a Korean swine farm infected with Type I PRRSV.
