[Comparative analysis of free HPV vaccination programs across countries with different income levels worldwide: from implementation to evaluation].

Abstract

Since the introduction of human papillomavirus (HPV) vaccines, countries around the world have actively promoted large-scale vaccination with HPV vaccines to improve their coverage for target populations. This study conducts a multidimensional analysis to quantify the policies, implementation models and evaluation outcomes of the free HPV vaccination program across countries at high, upper-middle and lower-middle income levels. The results reveal distinct patterns in implementation and evaluation among these countries. The results also suggest that China can learn from successful international experiences to explore more effective vaccination strategies to increase coverage. In parallel, it is essential to develop a scientifically grounded evaluation framework and conduct systematic evaluations to effectively support the continuous implementation of the free HPV vaccination program for target populations in China. Furthermore, China may consider incorporating appropriate HPV vaccines into the National Immunization Program and dynamically adjusting vaccine types as needed to accelerate the elimination of cervical cancer.
