/*
* Library: IMMZ.IND.43
* Immunization coverage for Varicella vaccinations (Computed Denominator)
* Compares the administered doses of varicella containing vaccine with the number of immunization recommendations for varicella vaccines expressed as a percentage.
*
* Numerator: Number of administrations of vaccines containing a varicella component during reporting period
* Numerator Computation: COUNT immunization events WHERE administered product is a Varicella vaccine (IMMZ.A1.DE.22) during reporting period
* Denominator: Number of immunization recommendations for varicella vaccines due during reporting period.
* Denominator Computation: COUNT immunization recommendation WHERE recommended product is varicella vaccine (IMMZ.A1.DE22) AND due date during reporting period.
*
* Disaggregation:
* - Dose Sequence (1, 2)
* - Age Group (< 12 months, 12 - 18 months, 18 - 36 months, 36 months - 12 years, > 12 years)
* - Geographic Region
* - Gender
