/*
 * Library: IMMZ.IND.03 Logic
 * Immunization coverage for pentavalent vaccine, 2nd dose
 * The percentage in the target population who have received a 2nd dose of pentavalent vaccine during the reporting period
 * 
 * Numerator: Number of pentavalent doses (2nd dose) administered through routine services during the reporting period
 * Numerator Computation: COUNT of immunization events WHERE "Vaccine type" = "Pentavalent vaccines" for the 2nd 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)
