From: Cost-effectiveness of human papillomavirus vaccination for prevention of cervical cancer in Taiwan
Sensitivity analysis of the incremental cost-effectiveness of vaccination compared to the current practice, with respect to the change in human papillomavirus (HPV) vaccine efficacy and immunity longevity. The squares represent a vaccine providing lifetime immunity to HPV-16 and HPV-18 (base case assumption). The triangles represent a vaccine that requires booster shots every 20 years to remain effective. The circles represent a vaccine that needs booster shots every 10 years to maintain effectiveness.
