Estimates and determinants of HPV non-vaccination in 14-year-old Canadians: Results from the childhood national immunization coverage survey, 2019.

Human papillomavirus (HPV) infections, the most common sexually transmitted infections, are associated with various health outcomes including anogenital warts and cancers. Despite significant investments in HPV vaccination programs, ensuring adequate vaccination coverage for adolescents remains a challenge in Canada. This analysis used data collected through the 2019 Childhood National Immunization Coverage Survey (CNICS) to determine national estimates of HPV non-vaccination and investigate determinants of HPV non-vaccination for adolescents aged 14-years old in Canada, both overall and stratified by gender.
