/*
 * Library: IMMZ.IND.13 Logic
 * Immunization coverage for Measles and rubella containing vaccine, 2nd dose
 * The percentage in the target population who have received second dose of measles and rubella vaccine during reporting period
 * 
 * Numerator: Number of measles and rubella doses (2nd dose) administered through routine services during reporting period
 * Numerator COUNT of immunization events WHERE "Vaccine type" = "Measles and rubella containing vaccines" for the second 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)

NOTE: This is an estimated denominator measure, meaning that all we are contributing from the site perspective is a count
towards the numerator, actual processing of this data to determine a proportion measure would be done by downstream analytics

For this reason, this measure is modeled as a cohort measure where membership in the cohort is determine by administration of
a measles containing vaccine.
