Immunological information
ATCvet code: QI09AD03.
The vaccine contains a modified live PRRS virus (genotype 1, subtype-1). It stimulates active immunity against PRRS virus. Vaccine efficacy has been demonstrated in laboratory vaccination and challenge studies using a genotype 1 subtype-1 strain.
Additional clinical studies demonstrated that intramuscular vaccination of seronegative 1-day-old piglets conferred protection against another subtype-1 strain (AUT15-33), a subtype-2 strain (BOR57) and a subtype-3 strain (Lena) of PRRS virus genotype 1.
