Evolving trends in HPV vaccination coverage among women aged 9–45 in Chengdu, China: insights from 2017 to 2023

Following the HPV vaccination program in Chengdu, the vaccination rate for girls aged 13-14 years significantly increased. However, the overall vaccination rate for women aged 9-45 years remains relatively low, particularly among certain subpopulations. To enhance overall vaccination rates, strategic priorities should include targeted interventions for subpopulations with suboptimal coverage, expansion of pilot programs, and stronger political commitment to integrating the HPV vaccine into the National Immunization Program.
