Generation of ORFV recombinants, which express different foreign genes (antigens), could be demonstrated to protect against lethal challenge infection with Herpesvirus (Herpes Suid 1), Borna disease Virus, Pestivirus (CSFV), Influenza virus (HPAIV H5N1), Rabies virus or Calicivirus (RHDV) not only in animal models, but also in natural hosts. Notably, ORFV recombinant replication is not needed to mediate protective immunity.

Innovative strategies for selection and generation of new, also multivalent ORFV recombinants are under development. Moreover, important unravelled questions remain to be solved concerning the unique immunostimulating properties of ORFV to activate innate and long-lasting adaptive (balanced Th1 and Th2 type response) immunity.
