Host Response |
Macaque Response
- Host Strain: cynomologus macaque
- Vaccination Protocol: cynomologus macaques were primed with rBCG-SIVgag, and then boosted with rDIsSIVgag (Ami et al., 2005).
- Vaccine Immune Response Type: VO_0003057
- Challenge Protocol: Ten weeks after the second booster immunization, the macaques were challenged by intrarectal inoculation with 2 × 10^3 TCID50 or 50 50% monkey infectious doses (MID50) of SHIV KS661c, an SHIV-89.6 variant clone (Ami et al., 2005).
- Efficacy: For the prime-boost vaccination group, plasma viremia levels remained undetectable and CD4+ T-cell counts stayed above 500 cells/μl for the entire year of testing (Ami et al., 2005).
