Unistrain PRRS Lyophilisate & Solvent for Suspension for Injection for Pigs

Unistrain PRRS is a vaccination that has an Intramuscular (IM) and an Intradermal (ID) version. It is indicated for use in pigs as follows:

Breeding females: For active immunisation of breeding females from farms affected with European PRRS virus to reduce reproductive disorders, incidence and duration of viraemia, transplacental virus transmission, virus tissue load and clinical signs in the offspring associated with infection with strains of PRRS virus.

Under laboratory conditions, vaccination of females reduced the negative impact of PRRS virus infection on piglet performance (mortality and weight gain) within the first 28 days of life.

Onset of immunity: 30 days after vaccination.
Duration of immunity: 16 weeks after vaccination.

Pigs from 4 weeks of age: For active immunisation of pigs from farms affected with European PRRS virus to reduce clinical signs associated with a PRRS virus infection, the incidence and duration of viraemia and the duration of virus shedding by infected animals. Under experimental conditions, it was demonstrated that vaccination reduces the virus tissue load in the lungs. Under field conditions, where a PRRSV infection occurred during the fattening period, a reduction in mortality and in the negative effects of infection on daily weight gain was demonstrated.

Onset of immunity: 28 days after vaccination.
Duration of immunity: 24 weeks after vaccination.
