HERBAVAC™ is a plant-derived recombinant subunit vaccine brand of BioApplications Inc.

HERBAVAC™ CSF Green Marker contains
a fusion protein that combines the E2 antigen and CBD (cellulose-binding domain). It does not contain Erns antigen, which is present in field strains and live attenuated vaccines.
Therefore, pigs vaccinated with HERBAVAC™ CSF Green Marker can be easily distinguished from pigs infected with field strains or live vaccinated.
