Comparison of immunization coverage estimates reported by select Canadian Provinces and as estimated by the 2013 childhood National Immunization Coverage Survey (cNICS): Measles
Notes:
1. Two-year old immunization coverage data for the Regional Health Authority of Vancouver Coastal Health are not included within the provincial estimate because coverage for this region is assessed periodically using survey methods.
2. Coverage estimates for Saskatchewan are based on children who were registered in the Saskatchewan Immunization management System (SIMS) and with provincial health coverage at the time of assessment.
3. Manitoba coverage estimates can be found online: http://www.gov.mb.ca/health/publichealth/surveillance/mims/docs/2012.pdf.
4. The reference birth cohort used by Quebec is children born between Oct 1, 2011 and Dec 31, 2011 and evaluated at 24 months of age in 2014.
5. The birth year cohort for the assessment of 2-year-old measles coverage in PEI are those born within the province during the 2011/12 fiscal year.
6. Immunization coverage for measles at 7 years-of-age in British Columbia is derived from Panorama and the immunization registry in use in Vancouver Coastal Health (PARIS). In three regional health authorities, Ministry of Education data is used for denominator estimates.
7. The exception to Ontario's 'complete for age' coverage methodology is the ability to report on coverage for measles, mumps and rubella by number of doses. Two doses measles coverage estimates are presented for the birth cohorts of 1995 and 2005 who were 7 and 17 years of age in the 2012-13 school year, respectively.
8. The coverage definition used by PEI is the receipt of 2 doses of measles-containing vaccine by the 6th birthday.
