Modified live vaccine has been used in United States since 1994, and other countries including Vietnam for Porcine Reproductive and Respiratory Syndrome (PRRS) control.

From 2010 Vietnam Animal Health Department has confirmed the highly pathogenic Porcine Reproductive and Respiratory Syndrome (HPPRRS) strain and its variants as frequent findings in pig farms causing PRRS outbreaks similar to that occuring in China. There are several reports on successful PRRSV controlling by using Ingelvac® PRRS MLV vaccine (Boehringer Ingelheim).

The aim of this study was to evaluate the field safety and efficacy of Ingelvac® PRRS MLV in improving and maintaining reproductive performance during a 3 years period on a pig farm in Vietnam.
