Vaccine Information |
- Vaccine Name: rFPV-AI-H5A-IL6
- Target Pathogen: Influenza virus
- Target Disease: Influenza (flu)
- Vaccine Ontology ID: VO_0004743
- Type: Recombinant vector vaccine
- Status: Research
- Host Species for Licensed Use: Baboon
- Vector:
- Preparation: Recombinant fowlpox virus (rFPV-AIH5AIL6) coexpressing the haemagglutinin (HA) gene of the H5N1 subtype of the avian influenza virus (AIV) and chicken interleukin 6 gene (Qian et al., 2012).
- Immunization Route: Intramuscular injection (i.m.)

Host Response |
Ducks Response
- Vaccination Protocol: The ducks were immunized subcutaneously with rFPV-SYHA, rFPV-AIH5AIL6, rFPV-IL6 and wt-FPV, respectively, at a titre of 105 PFU in a 0.2-ml inoculum (Qian et al., 2012).
- Vaccine Immune Response Type: VO_0003057
- Challenge Protocol: Each duck was challenged with 0.2 ml of 105.75 EID50 of H5 AIV A/mallard/Huadong/SY/2005 by nose/eye drop (Qian et al., 2012).
- Efficacy: These animal studies demonstrated that rFPV-AIH5AIL6 induced a higher anti-AIV HI antibody response, an enhanced lymphocyte proliferation response, an elevated immune protection, and a reduction in virus shedding compared to a recombinant fowlpox virus expressing the HA gene alone (rFPV-SYHA) (Qian et al., 2012).
