Mouse Response

• Vaccine Immune Response Type: VO_0003057
• Immune Response: The DRF-412 vaccine vector was as effective as live RSV in inducing neutralization antibody, systemic Ab (IgG, IgG1, IgG2a, and IgG2b) responses, and mucosal antibody responses (Ig A). Mice inoculated with vector DRF-412 induced a higher mixed Th1/Th2 cytokine immune response than DRF-412-P (Wu et al., 2009).
• Efficacy: Mice immunized with DRF-412 and DRF-412-P have a higher average Ct value compared with PBS and phCMV I group (P < 0.001), which means that they have less viral mRNA in the lung indicating better protection, but there was no statistically significant difference between DRF-412 and DRF-412-P. This vaccine induced partial protection against RSV in mice (Wu et al., 2009).
