Table 4 Invasive Neisseria meningitidis from Québec, Canada in 2009-2013: predicted vaccine coverage based on at least one antigen showing an exact match to the 4CMenB vaccine components or with Novartis variant 1 factor H binding protein (fHbp)/Neisseria adhesin A (NadA) peptides belonging to variants 1 to 3

  1. a4CMenB vaccine components include: factor H binding protein (fHbp) peptide 1; Neisseria Heparin Binding Antigen (NHBA) peptide 2; Neisseria adhesion A (NadA)-2/3 peptide 8; and outer membrane protein porin A (PorA) P1.4
  2. bNovartis variant 1 peptides were indicated by their peptide number possibly covered by the vaccine; whereas variants 2/3 peptides were labelled as No to indicate no match or not covered by the 4CMenB vaccine
  3. cNadA variant 1-3 peptides were indicated by their peptide number; whereas No was used to indicate absence of the nadA gene
  4. dNot assigned to any known clonal complex according to the current Neisseria MLST website (http://pubmlst.org/neisseria/)
