PRRS is one of the most costly diseases in German swine production. To prevent losses due to PRRSV mass vaccination of the whole herd with a US-strain based modified life vaccine (Ingelvac PRRS MLV, Boehringer Ingelheim) has become a standard intervention in Germany.
This paper describes the stabilisation of a 6000 sow herd by mass vaccination and the value of statistical analysis of serological and production parameters to help making decisions and monitor the success of intervention strategies.
