The costs of developing and producing new-generation vaccines have increased compared to many of the older, "traditional" vaccines because of new technologies and regulatory requirements. While the public sector often supports basic research costs, private manufacturers are usually responsible for the investments in product development and production scale-up. When considering investments, firms evaluate the probability of a market. Unfortunately, the developing country vaccine market is small (in revenue terms) and often unpredictable, particularly given inaccurate forecasting in the past. Low-income developing countries expect low prices. Demand (actual decisions to pay for and introduce the vaccine) is almost always lower than need (estimates of requirements to achieve optimal public health outcomes), a distinction that may be even more significant for HPV vaccines given the number of new vaccines against priority diseases that will become available over the coming 5 years. One new mechanism under consideration to address some of these challenges is Advanced Market Commitments (AMCs). By providing an assured price subsidy for developing country purchase of a future vaccine meeting predefined standards, an AMC would provide industry with greater assurances of earning a reasonable return on their investment to serve the poorest developing countries. The AMC mechanism could provide critical motivation for increased industry (private) investment that would otherwise not occur. HPV vaccines are one of six vaccines being considered for a possible AMC pilot.

Background: Understanding the HPV genotype distribution in invasive cervical cancer (ICC) is essential for vaccine optimization. This study presents a comprehensive analysis of HPV genotypes in ICC tissues from patients in western China, with the aim of informing regional vaccine policy and prevention strategies.
Methods: DNA was extracted from 1,908 paraffin-embedded ICC samples, and 23 HPV genotypes were detected via PCR and reverse dot hybridization gene chip assays.

Objectives: As one type of vaccine policy, the effectiveness and spillover effects of the US CDC vaccine recommendations are inadequately evaluated. This study aims to fully evaluate its impacts on male adults, in addition to children, using better data.
Design: A before-after study design to examine the CDC's 2011 HPV vaccine recommendation for men aged 11-21.

Introduction: Immunocompromised persons have high risk of persistent human papillomavirus (HPV) infection and HPV-related diseases, and lower immune response to vaccines. This study evaluated the immunogenicity and safety of administering a fourth dose of quadrivalent (4v)HPV vaccine in immunosuppressed women who did not seroconvert after three doses.
Methods: An open-label, not-controlled trial included immunosuppressed women (solid organ transplant patients and women receiving treatment for SLE) who did not seroconvert to at least one of the four HPV vaccine types after three 4vHPV vaccine doses.

Background: The prophylactic vaccines available to protect against infections by human papillomavirus (HPV) are well tolerated and highly immunogenic. This systematic review and meta-analysis aimed to explore the efficacy of HPV vaccination on the risk of HPV infection and recurrent diseases related to HPV infection in individuals undergoing local surgical treatment.
Methods: A literature search was performed using PubMed/MEDLINE, Embase, the Cochrane Library, Scopus, Web of Science, and bioRxiv/medRxiv from inception to July 15, 2024.
