Highly Pathogenic Porcine Reproductive and Respiratory Syndrom Virus (HP PRRS) emerged in China in 2006. It broke out again in May 2009 in Jiangsu, Anhui provinces and re-emerged for the third time in May 2010, HP PRRS swept over the major swine rearing areas in China within 4 months. Controlling HP PRRS and reducing its economic impact are priorities for the government and hog producers.
One challenge study already showed that Ingelvac® PRRS MLV was effective in reducing the clinical signs and lesions when challenged with an HP PRRS strain.
This case control report confirms the efficacy of Ingelvac® PRRS MLV against HP PRRS in a the field particularly in a 3500 sows pig farm in Northern China.
