Research Question

  • The identification of a suitable vector for the expression/delivery of protective ASFV antigens

Research Gaps and Challenges

  • Ensure the expression of the antigens to induce a protective immune response.
  • Identify the best vector among those that already went through the regulatory process.
  • Create stable genetically modified organisms expressing the desired ASFV antigens

Solution Routes

  • Generate genetically modified organisms (viruses or bacteria) expressing the protective antigens of different ASFV strains
  • Use recombinant vaccine strains containing individual ASFV gene/s as vectors
  • Use recombinant ASFV subunit vaccines using swinepox virus as vector
  • Incorporate molecular adjuvants (expressing CD40 ligand)

Dependencies

  • Identify the most appropriate antigens
  • Ensure sufficient expression level
  • Develop capacity to test the expression
  • Identify the most suitable delivery systems (e.g. oral for wild suids in Europe)
  • Identify vectors being suitable for one dose administration
