  1. aZERO, the child didn’t receive any vaccine by 12 months old; FULL, the child is under 24 months old and is fully immunized for their age; COMPLETE, the child is above 24 months and completed the routine paediatric immunization schedule
  2. bConcentration index based on households ranked by socioeconomic status (as defined in the DHS) only
  3. cFor mathematical reasons, when the prevalence/coverage outcome is low (in this case, 2.2%), the Wagstaff and Erreyger indices may produce conflicting results in terms of order of magnitude: the Wagstaff index reported a value of 0.425 (significant inequity) whereas the Erreyger corrected index was 0.022 (very equitable distribution). Both indices are positive: privileged people benefit most
