Decision-making on childhood varicella vaccination should also include consideration of the possible impact on herpes zoster.\nThe number of doses recommended is dependent on the goal of the vaccination programme. One dose is sufficient to reduce mortality and severe morbidity from varicella but not to prevent limited virus circulation and outbreaks. Two doses have higher effectiveness and should therefore be recommended in countries where the programmatic goal is, in addition to decreasing mortality and severe morbidity, to further reduce the number of cases and outbreaks.\n*/\ndefine \"Two varicella primary series doses were administered\":\n \"Number of Varicella Primary Series Doses Administered\" = 2" ] ], [ fhir:index 3 ; fhir:Extension.url [ fhir:value "displaySequence" ] ; fhir:Extension.valueInteger [ fhir:value "31"^^xsd:integer ] ] ; fhir:Extension.url [ fhir:value "http://hl7.org/fhir/StructureDefinition/cqf-logicDefinition" ] ], [ fhir:index 32 ; fhir:Element.extension [ fhir:index 0 ; fhir:Extension.url [ fhir:value "libraryName" ] ; fhir:Extension.valueString [ fhir:value "IMMZD2DTVaricella2DosesLogic" ] ], [ fhir:index 1 ; fhir:Extension.url [ fhir:value "name" ] ; fhir:Extension.valueString [ fhir:value "Varicella immunization schedule is complete" ] ], [ fhir:index 2 ; fhir:Extension.url [ fhir:value "statement" ] ; fhir:Extension.valueString [ fhir:value "/*\n@output: Varicella immunization schedule is complete\n@pseudocode: \"Immunization recommendation status\" = \"Complete\"\n*/\ndefine \"Varicella immunization schedule is complete\":\n Encounter.\"Two varicella primary series doses were administered\"" ] ], [ fhir:index 3 ; fhir:Extension.url [ fhir:value "displaySequence" ] ; fhir:Extension.valueInteger [ fhir:value "32"^^xsd:integer ] ] ; fhir:Extension.url [ fhir:value "http://hl7.org/fhir/StructureDefinition/cqf-logicDefinition" ] ], [ fhir:index 33 ; fhir:Element.extension [ fhir:index 0 ; fhir:Extension.url [ fhir:value "libraryName" ] ; fhir:Extension.valueString [ fhir:value "IMMZD2DTVaricella2DosesLogic" ] ], [ fhir:index 1 ; fhir:Extension.url [ fhir:value "name" ] ; fhir:Extension.valueString [ fhir:value "Varicella immunization schedule is complete Guidance" ] ], [ fhir:index 2 ; fhir:Extension.url [ fhir:value "statement" ] ; fhir:Extension.valueString [ fhir:value "/*\n@output: Varicella immunization schedule is complete Guidance\n@guidance: Varicella immunization schedule is complete.
