/*
* Library: IMMZ.IND.02
* Immunization coverage for DTP containing vaccines (Estimated Denominator)
* Compares the administered doses of a DTP containing vaccine with the estimated number of surviving infants as a percentage.
*
* Numerator: Number of administrations of vaccinations containing a Diphtheria, Tetanus, and Pertussis component during the reporting period
* Numerator Computation: COUNT immunization events WHERE administered product is a DTP vaccine (IMMZ.A1.DE24) during reporting period
* Denominator: Estimated number of surviving infants.
* Denominator Computation: PARAMETER surviving number of infants
*
* Disaggregation:
* - Dose Sequence (1, 2, 3)
* - Age Group (< 1 year or >1 year)
* - Geographic Region
* - Administrative Gender (or Biological Sex)
