Human papillomavirus (HPV) vaccines received regulatory approval and were recommended for use in young girls nearly 2 decades ago. Uptake is mostly high in resource-rich settings. In resource-limited settings, where the burden of cervical cancer is disproportionately high, access to and uptake of HPV vaccines are nowhere near satisfactory, despite evidence that HPV vaccination is highly cost-effective and a significant value-for-money investment. The discovery that only a single dose of the HPV vaccines may be needed to confer adequate protection may make equitable access to HPV vaccines possible. Indeed, the recent World Health Organization recommendation allowing for 1 or 2 doses is already gaining traction. This monograph aims to update the state of the science related to single-dose HPV vaccine protection and includes both primary data and modeling efforts that address key gaps in the knowledge regarding 1) durability of protection of a single dose of the HPV vaccine, 2) single-dose HPV vaccine effectiveness in both high-income and low-income settings, 3) implementation of single-dose HPV vaccination, and 4) how to accelerate control of cervical cancer by integrating a 1-time screen for cervical disease. The content published in this monograph will continue to advance the science of HPV vaccination and will be vital as new countries make informed decisions about how best to use this remarkable vaccine.
