Beneficial impact of a PRRSV vaccination program combining a modified live vaccine and PROGRESSIS® on virus circulation and technical performance
PRRS is one of the most significant pig diseases in the modern swine industry. The addition of a killed vaccine (KV) vaccination at D90 of gestation in farm where sows are regularly vaccinated with a modified live vaccine (MLV) have been shown to contribute to the stabilization of the sows, leading to a better control of PRRS virus circulation in the pig flows, writes Luk Willems, DVM, Clinique Vétérinaire de L’Elorn, France.
