Popis: Swine Influenza Virus (SIV) a type A Orthomyxovirus is responsible for Swine Influenza, an acute infectious disease responsible for severe economic losses for pig producers. Three antigenically distinct subtypes H1N1, H3N2 and H1N2 can be found in the pig. The aim of this study was to evaluate the efficacy of a third vaccination administered at 6 months of age. Italian pigs are in fact slaughtered at 9 months of age at a weight >150 kg, and classic vaccination schemes do not induce a high immunity level till throughout the growing period.
