Vaccine Detail
BoHV-4-A-IgK-VP2gD |
Vaccine Information |
- Vaccine Name: BoHV-4-A-IgK-VP2gD
- Target Pathogen: Bluetongue virus
- Target Disease: Bluetongue disesase
- Vaccine Ontology ID: VO_0004686
- Type: Recombinant vector vaccine
- Status: Research
- Host Species for Licensed Use: Cattle
- Vector: BoHV-4 vaccine vector
- Preparation: BoHV-4-based vector cloned as a bacterial artificial chromosome (BAC) was engineered to express the bluetongue virus (BTV) immune-dominant glycoprotein VP2 provided of a heterologous signal peptide to its amino terminal and a trans-membrane domain to its carboxyl terminal (IgK-VP2gDtm), to allow VP2 expression targeting to the cell membrane fraction (Franceschi et al., 2011).

Host Response |
Mouse Response
- Host Strain: α/β interferon receptor knockout (IFNAR(-/-)) mice
- Vaccination Protocol: IFNAR(-/-) mice intraperitoneally inoculated twice with BoHV-4-A-IgK-VP2gDtm at different time points.
- Vaccine Immune Response Type: VO_0000287
- Immune Response: Mice eveloped serum neutralizing antibodies against BTV .
- Side Effects: A pre-challenge experiment was performed to test BoHV-4 safety on adult α/β interferon receptor knockout (IFNAR(-/-)) mice, a newly generated bluetongue laboratory animal model. BoHV-4 infected IFNAR(-/-) mice did not show clinical signs even following the inoculation of BoHV-4 intra-cerebrally, although many areas of the brain got transduced (Franceschi et al., 2011).
- Challenge Protocol: a lethal dose of BTV-8 as used for challenge (Franceschi et al., 2011).
- Efficacy: Vaccinated mice showed a strongly reduced viremia and a longer survival time after challenge (Franceschi et al., 2011).
