Table 1.

Vaccination coverage indicators analysed.

Indicator* Definition Remarks
  • 1.

    Coverage before the SIA

 Proportion of children aged 9–59 months at the time of the SIA who had a history of receipt of MCV before the SIA (according to vaccination card or parental recall) Measures the combined effect of RI and previous SIAs on MCV coverage in the current SIA target population
  • 2.

    SIA coverage among MCV zero-dose children

 Proportion of children aged 9–59 months at the time of the SIA with NO history of receipt of MCV before the SIA who received a dose of MCV during the SIA (by card, finger-mark or parental recall) Measures the effectiveness of the SIA in terms of reaching children most in need of MCV
  • 3.

    SIA coverage among children vaccinated

previously		 Proportion of children aged 9–59 months at the time of the SIA with a history of receipt of MCV before the SIA who received a dose of MCV during the SIA (by card, finger-mark or parental recall) Measures the effectiveness of the SIA in terms of reaching children who have already received at least one dose of MCV
  • 4.

    Overall SIA coverage

 Proportion of children aged 9–59 months at the time of the SIA who received a dose of MCV during the SIA (by card, finger-mark or parental recall) Measures the effectiveness of the SIA in reaching all children in the target population
  • 5.

    Coverage before and during the SIA

 Proportion of children aged 9–59 months who had a history of MCV vaccination before the SIA AND who received a dose during the SIA Measures coverage with at least 2 lifetime doses**of MCV by the end of the SIA
Comparison of this indicator with indicator 2 shows how well the SIA reaches the hard-to-reach compared to children already vaccinated
  • 6.

    Coverage before and/or during the SIA

 Proportion of children aged 9–59 months who had a history of MCV vaccination before the SIA AND/OR who received a dose during the SIA Measures coverage with at least one lifetime dose of MCV** by the end of the SIA
