Robust data support the use of MenACWY-TT in infants starting as early as 6 weeks of age. MenACWY-TT was safe and well tolerated in infants, was immunogenic after priming and booster, and demonstrated persistent immunogenicity. Lower persistence for serogroup A relative to other serogroups based on serum bactericidal assays (SBAs) using human complement appears to be a class effect of MenACWY conjugate vaccines. Correlates of protection other than SBA are being explored, including immunologic responses associated with different carrier proteins.
