Key points:
- The objective of this study was to quantify the effect of MLV vaccine on performance and measure wild-type virus shedding to sentinels and in aerosol.
- The duration and frequency of PRRSV RNA detection in air was significantly higher in non-vaccinated controls than in the group vaccinated with Ingelvac PRRS MLV.
- The observed performance benefits as well as shedding reduction in vaccinated pigs challenged with wild-type virus support the recommendation of MLV vaccination of growing pigs at risk of infection.
