Research Question

  • The development of a subunit vaccine where ASFV gene/s is cloned into DNA constructs that are used as immunogens, providing broad cross-protective immunity and is safe

Research Gaps and Challenges

  • Identify ASFV gene products that can induce a protective immune response to engineer subunit vaccines
  • Have it multivalent
  • Stimulate protective response involving both VN Abs and CTC

Solution Routes

  • Multimeric scaffold could be an important research target of priority

Dependencies

  • Identify protective antigens and the antigen combination to give widest protection against the various field isolates
  • Select the best adjuvants
  • Select the best production system
  • Select the best antigen presentation system, e.g. multimeric scaffold, VLPs etc
  • Identify a combination of antigens that would generate protective responses or a common single antigen to which immune responses are normally suppressed

State Of the Art

  • Up to now, all subunit candidates failed
