Definition: The percentage of girls in the age group/school grade targeted for immunization that have completed the HPV vaccine series based on the provincially/territorially recommended vaccination schedule
Rationale for measurement: Reporting on HPV vaccination uptake helps to inform opportunities to increase efforts in prevention activities.
Measurement timeframe: School years 2015/16 to 2016/17 (measurement timeframe varies by jurisdiction – refer to ‘Data Availability’ section)
Denominator: Number of girls in the target grade/age group in schools for the provincial/territorial school-based HPV vaccination program.
Numerator: Number of girls who have received the final dose (second or third dose, depending on the province/territory) of the HPV vaccination through the provincially/territorially organized program
Exclusion criteria: Not applicable
School year 2015/16: MB, ON, NS, PE, NL, NT
School year 2016: SK
School year 2016/17: BC, AB, QC, NB, YT
Stratification: By province/territory
Data source: Provincial/territorial immunization programs
Data retrieval date: December 2017
Variables details: Not applicable
Notes from jurisdictions:
NT: Vaccination occurs in grades 4–6. Vaccination uptake listed is for grade 7 girls.
SK: HPV vaccination is offered in grade 6, but immunization coverage rates in SK are assessed based on an age cohort. HPV vaccination uptake is assessed at age 13. Saskatchewan switched to the two-dose series on September 1, 2015. Most of the 13-year-old girls in 2016 would have been initially offered the three-dose series.
ON: Routine coverage monitoring in Ontario assesses children by birth year as a proxy for grade. Female students who turned 13 years of age by December 31st, 2015 (born in 2002) were used to estimate coverage in grade 8 girls. Girls who completed a valid 2 dose or 3 dose HPV immunization series are represented in the coverage estimate in the column marked ‘2nd dose’. Although the routine school-based program typically administers a 2 dose series, some girls require 3 doses based on age at first dose or if immunocompromised.
YT: Girls who received ≥ 2 or 3 dose series completion as defined by age of 1st dose. Two valid dose(s) of HPV if series started before 15 years of age; 3 valid doses if series started on or after 15 years of age.
