Predicted vs observed effectiveness of outer membrane vesicle (OMV) vaccines against meningococcal serogroup B disease: Systematic review.

Human serum bactericidal antibody levels (hSBA) are commonly used as an immune correlate of protection after vaccination against meningococcal disease. We performed a systematic review of how well this marker correlates with protection induced by outer membrane vesicle (OMV) vaccines against meningococcal B (MenB) disease.
