Vector identification for vectored vaccine

Research Question

Using a replicating organism to express the protective antigens for the various parasite species, thereby generating a stronger longer-lasting immune response

Research Gaps and Challenges

  • Detrimental immune response against the vector.
  • Vector delivering appropriate antigens in optimal configuration to trigger protective immune response.

Solution Routes

  • Explore a range of possible vectors – large viruses (Herpes viruses, endogenous retroviruses), protozoa (Trypanosoma Theileria, Eimeria), bacteria (replication deficient, such as aroA mutants

Dependencies

  • Identity of relevant protective antigens.
  • Understanding the protective mechanism for the respective parasite species.
  • Understanding dynamics of polyvalent protective immune responses to avoid unintended consequences
