/*
 * Library: IMMZ.IND.01
 * Immunization coverage for BCG (Estimated Denominator) 
 * Compares the doses of BCG vaccine administered with the estimated number of live births as a percentage.
 * 
 * Numerator: Number of administrations of BCG during the reporting period 
 * Numerator Computation: COUNT immunization events WHERE administered product is a BCG vaccine (IMMZ.A1.DE1) during reporting period
 * Denominator: Estimated number of live births.
 * Denominator Computation: PARAMETER number of live births
 * 
 * Disaggregation:
 *   - Geographic Region
 *   - Administrative Gender (or Biological Sex)
