* Immunization coverage for pneumococcal conjugate vaccine, 3rd dose
* The percentage in the target population who have received a 3rd dose of pneumococcal conjugate vaccine during the reporting period
*
* Numerator: Number of pneumococcal vaccine doses (3rd dose) administered through routine services during the reporting period
* Numerator Computation: COUNT of immunization events WHERE "Vaccine type" = "Pneumococcal vaccines" for the 3rd dose in the primary series AND "Date and time of vaccination" is during the reporting period
* Denominator: Number in target group
* Denominator Computation: As defined by the Member States

* Disaggregation
* - Administrative area
* - Sex
* - Age in years
* - Age group (depending on schedule)

* Annotations: The calculation for this indicator is in line with the administrative calculation provided on the WHO Immunization data portal.
* As per WHO Immunization data portal, recommended denominator used in the administrative coverage calculation is surviving infants for doses recommended in the first year of life. Then, the single age cohort population estimates for the targeted cohort.
