The BI approach to PRRS control

The core aims of an effective PRRS control strategy should be to prevent infection, maximise immunity, and minimise exposure to the virus.

PRRS control is much more than just vaccination alone. It requires a comprehensive understanding of the disease and the production system under threat, the use of multiple management tools, and a systematic approach to management, in order to achieve long-term success.


Prevent introduction of new virus through optimisation of biosecurity and pig flow management.


Establish a solid immunity in the whole herd population through vaccination of both sows and piglets with a vaccine which is effective across a wide range of PRRSV strains.


Reduce circulation of resident virus using a PRRS control programme tailored to the needs of the farm.
