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).
