Impact and health economic evidence for HPV immunization policy and program
OncoSim modelling on the impact of HPV and cervical cancer prevention interventions indicates that high coverage of HPV immunization (90%) coupled with HPV testing and appropriate and timely follow-up can prevent 6,810 cervical cancer cases by 2050, resulting in 1,750 lives saved.
- Offering HPV immunization programs, as well as offering them through school-based programs has been shown to be cost effective in high-income countries, including Canada.1
- The effectiveness of the vaccine in females has been found to diminish as recipients age, as the vaccine is most effective when administered prior to the onset of sexual activity.
- Administering vaccination to girls before age 14 has consistently been found to be the most cost-effective strategy.2
- While school-based programs remain the primary model for HPV vaccination delivery, one model found that the most cost-effective way to offer HPV vaccinations is through schools and primary care settings as compared to a school-only approach or through utilizing any law mandating immunization.3
- Ultimately, in combination with screening, HPV vaccination has been shown to be a cost-effective intervention in high-income countries, and HPV DNA testing has been identified as a cost-effective strategy across populations.4
