Development of a vectored Brucella vaccine
Vectored Vaccines
Research Question
- The development of an effective novel vaccine.
- A replicating organism expressing the correct combination of Ags is more likely to generate the required type of immune response but as it would have a restricted combination of Brucella antigens it is unlikely to give false positive test results in the standard skin test
Research Gaps and Challenges
- Generating a strong protective immune response
- Preventing the development of immune responses to the vector
Solution Routes
- Establishing the immune responses to Brucella antigens following vaccination with the vectored vaccine.
- Establishing the immune responses to the vector
- Challenge experiments involving animals vaccinated with candidate organisms.
Dependencies
- Identifying a combination of antigens for expression by a vector or a common single Ag to which immune responses are normally suppressed
- Identifying a suitable vector
