Development of a cross protective/multivalent vectored PRRSV vaccine

Research Question

  • The development of an effective vaccine that gives broad cross-protection but doesn’t contribute to virus evolution

Research Gaps and Challenges

  • Generating a strong protective immune response with CTCs and VN Abs
  • Preventing the development of immune responses to the vector

Solution Routes

  • Monitoring the immune response following immunisation with the various candidates involving single/combination of antigens
  • Challenge experiments with the various vaccine candidates
  • Development of vaccine platforms Identify most appropriate route of administration (parenteral/oral/nasal)

Dependencies

  • Identifying a combination of antigens for expression by a vector or a common single Ag to which immune responses are normally suppressed
  • Identifying suitable vector
