Subunit vaccines

Research Question

  1. Assess if subunit platform technologies can be used to develop safer and more efficacious vaccines than current LAVs.
  2. Identify and test candidate subunit vaccine antigens.

Research Gaps and Challenges

  1. Develop a thermotolerant subunit vaccine with DIVA properties.
  2. Subunit-based vaccines still at the experimental stage.
  3. Lack of in vitro assays to guide immunogenicity and efficacy testing.

Solution Routes

  1. Reverse vaccinology approaches to antigen identification are being tested.
  2. Identify antigens for a DIVA vaccine.
  3. Assess formulations, route and dose of immunization in small-scale immunogenicity studies.
  4. Assess ability to meet minimal and desired TPPs.
  5. Assess ability to scale-up and manufacture.

Dependencies

  1. Standardized cattle breed specific laboratory challenge models that reproduce CBPP caused by natural infection or are acceptable surrogates.
  2. Better understanding of immune correlates of protection.
  3. Assess ability to meet minimal and desired TPPs.
  4. Assess ability to scale-up and manufacture.

State Of the Art

  1. A combination of four proteins for an experimental vaccine has been identified. This does not preclude the need for identification of additional antigens.
