The development of human papillomavirus (HPV) vaccines has made substantive progress, as represented by the approval of five prophylactic vaccines since 2006. Generally, the deployment of prophylactic HPV vaccines is effective in preventing newly acquired infections and incidences of HPV-related malignancies. However, there is still a long way to go regarding the prevention of all HPV infections and the eradication of established HPV infections, as well as the subsequent progression to cancer. Optimizing prophylactic HPV vaccines by incorporating L1 proteins from more HPV subtypes, exploring adjuvants that reinforce cellular immune responses to eradicate HPV-infected cells, and developing therapeutic HPV vaccines used either alone or in combination with other cancer therapeutic modalities might bring about a new era getting closer to the vision to get rid of HPV infection and related diseases. Herein, we summarize strategies for the development of HPV vaccines, both prophylactic and therapeutic, with an emphasis on the selection of antigens and adjuvants, as well as implications for vaccine efficacy based on preclinical studies and clinical trials. Additionally, we outline current cutting-edge insights on formulation strategies, dosing schedules, and age expansion among HPV vaccine recipients, which might play important roles in addressing barriers to vaccine uptake, such as vaccine hesitancy and vaccine availability.
人乳头瘤病毒(HPV)疫苗的发展取得了实质性进展,自 2006 年以来,已有五种预防性疫苗获得批准。一般来说,预防性 HPV 疫苗的部署可有效预防新感染和 HPV 相关恶性肿瘤的发生。然而,在预防所有 HPV 感染和消除已建立的 HPV 感染以及随后进展为癌症方面,还有很长的路要走。通过纳入更多 HPV 亚型的 L1 蛋白来优化预防性 HPV 疫苗,探索增强细胞免疫反应以消除 HPV 感染细胞的佐剂,以及开发单独使用或与其他癌症治疗方式联合使用的治疗性 HPV 疫苗,可能会带来一个接近消除 HPV 感染和相关疾病的愿景的新时代。在此,我们总结了预防性和治疗性 HPV 疫苗的开发策略,重点介绍了抗原和佐剂的选择,以及基于临床前研究和临床试验的疫苗疗效的意义。此外,我们还概述了 HPV 疫苗接种者的配方策略、剂量方案和年龄扩展方面的当前最新进展,这些进展可能在解决疫苗接种障碍方面发挥重要作用,如疫苗犹豫和疫苗供应。
