Population-level impact of HPV vaccination in British Columbia

Leveraging population data to understand trends in HPV related disease & cancers in British Columbia

The school-based HPV vaccination program for girls born in 1994 or later was launched in British Columbia in September 2008. Administration of the HPV vaccine for the entire province is tracked at the BC Centre for Disease Control, while all cervical cancer screening & follow-up records are managed at the BC Cancer, Cervical Cancer Screening Program. By linking these data sources, we will evaluate the effectiveness of the HPV vaccination program, and monitor the impact on intermediate endpoints of cervical cancers. From this evaluation, we will be able to determine whether the school based HPV vaccine program reduced the rates of cervical precancerous lesions and describe HPV vaccine effectiveness at a population level.
