Mouse Response

• Host Strain: NIH
• Vaccination Protocol: Each mouse received 0.2 ml, containing 10 μg of rTbpA protein and Freund's complete adjuvant, by subcutaneous injection. All animals were immunized on days 1, 21, and 28 (West et al., 2001).
• Challenge Protocol: Mice were infected by intraperitoneal injection of N. meningitidis at several challenge doses (West et al., 2001).
• Efficacy: 100% protection was afforded by vaccination with rTbpA at the 2 × 10^7 CFU challenge dose andat the 2 × 10^8 CFU challenge dose, the rTbpA-vaccinated group had an 85% survival rate (West et al., 2001).
