Determination of the virulence of a mutant PCV2 (PCV2d) recently identified in cases of apparent vaccine failure and the ability of commercial PCV2a vaccines to protect against PCV2d
July 4, 2014By Tanja Opriessnig
PCV2d (formerly known as mutant or mPCV2) emerged in the U.S. in 2012 and important questions on virulence of this novel strain and vaccine protection by currently used vaccines needed to be...
