Seriological evaluation of two different schemes of mass herd vaccination using modified live vaccine (MLV) in a PRRSV control program

The results of this study show the efficacy of mass herd vaccination to stabilize the sow herd and to production of naïve weaned pigs, allowing a better assessment of control tools of PRRSV in growing pigs.

Porcine reproductive and respiratory syndrome virus (PRRSV) produces reproductive and respiratory disease in sows and pigs, Herd mass vaccination has demonstrated to be an effective tool to stabilize the sow herd; therefore improving reproductive efficiency and allowing the production of naïve pigs at weaning.

The objective of this study was to monitoring the serological response on two different schemes of mass herd vaccination with Modified Live Vaccine (Ingelvac® PRRS MLV).
