METHODS OF REDUCING VIRUCIDAL ACTIVITY IN PCV-2 COMPOSITIONS AND PCV-2 COMPOSITIONS WITH AN IMPROVED IMMUNOGENICITY

摘要

The present invention provides methods of reducing the vircidal activity of a composition comprising a PCV-2 antigen as well as antigenic preparations and immunogenic compositions comprising a PCV-2 antigen, wherein the virucidal activity has been reduced. In addition, the present invention also relates to a method of increasing the immunogenicity of an immunogenic composition comprising a PCV-2 antigen as well as immunogenic composition with an increased immunogenicity.
