Method for reducing virus shedding, tissue colonization, and lymphoid depletion caused by or associated with PCV2 infection

Abstract

(PCV2) infection in a pig, the method comprising administering orally to the pig an immunogenic composition comprising non-replicating PCV2 antigen. In one example, an immunogenic composition is administered via the oral route to a pig, wherein the immunogenic composition comprises a recombinantly produced and purified PCV2 ORF2 protein. This allows to simply reduce virus shedding, colonization of lymphoid tissue, and / or lymphoid depletion caused by associated with a PCV2 infection in the pigs, while simultaneously reducing the propensity for adverse reactions, eliminating the risk of injection site reactions, avoiding pain, and putting less stress on the animals.
