Pre-adolescent vaccination of girls against human papillomavirus (HPV) is effective with high coverage and lifelong protection, complementing existing cervical cancer screening. Catch-up programs and vaccinating boys show less cost-effectiveness and more uncertainty.
Area of Science:
- Public Health
- Epidemiology
- Mathematical Modeling
Background:
- Cytology screening significantly reduces cervical cancer mortality.
- Integrating human papillomavirus (HPV) vaccination into existing screening programs presents policy challenges.
- Mathematical models are crucial for evaluating HPV vaccination strategies.
Purpose of the Study:
- To review mathematical models evaluating HPV vaccination in developed countries with screening programs.
- To identify consensus and divergent findings regarding HPV vaccination policies.
- To inform decision-making for cervical cancer prevention.
Main Methods:
- Focused review of existing decision-analytic models for HPV vaccination.
- Analysis of models simulating disease burden and intervention cost-effectiveness.
- Evaluation of vaccination target ages, catch-up programs, and inclusion of boys.
Main Results:
- Pre-adolescent girls' vaccination is attractive with high, lifelong coverage, complementing current screening.
- Catch-up vaccination effectiveness decreases with extended age ranges.
- Vaccinating boys is unlikely to be cost-effective if girls' coverage is adequate.
Conclusions:
- HPV vaccination of girls, with high coverage and lifelong protection, is a valuable addition to cervical cancer prevention.
- Uncertainty remains regarding optimal catch-up strategies and the cost-effectiveness of vaccinating boys.
- Further research is needed to optimize combined primary and secondary prevention strategies.
