PRRS modified live vaccine plays an important role in controlling Porcine Reproductive and Respiratory disease. Serology is a readily available monitoring tool to assess PRRS exposure dynamics in herds under a PRRS stabilization program. This paper describes SP value variation over 5 years in a farrow to finish farm applying Ingelvac® PRRS MLV (Boehringer Ingelheim, St. Joseph, MO, USA) as a primary tool to achieve stabilization.
