Filter by:This study aims to demonstrate that a 2-dose regimen of the 9-Valent Human Papillomavirus (9vHPV) vaccine (GARDASIL™9, V503) induces non-inferior competitive Luminex immunoassay (cLIA) geometric mean titers (GMTs) to each of the 9vHPV vaccine types in Chinese girls 9 through 14 years of age compared to a 3-dose regimen in Chinese women 20 through 26 years of age. The primary hypothesis is that a 2-dose regimen has a non-inferiority margin of 0.67 in the GMT ratio (girls vs. women) for each HPV type.
Human papillomavirus (HPV) causes the most prevalent sexually transmitted infections in the world. The nonavalent HPV vaccine (9vHPV) provides protection against 9 high-risk HPV serotypes, responsible for causing approximately 90% of cervical and other HPV-related anogenital cancers, as well as 90% of genital warts. The risk of cancer is substantially increased among immunocompromised patients. Although studies have demonstrated seroprotection among children and adolescents, boys and girls, with the 9vHPV vaccine, the immunogenicity of this vaccine has been poorly explored in immunocompromised children and adolescents (including transplant patients, and those infected with human immunodeficiency virus (HIV)). Several factors, including the immunological consequences of vertically acquired infection, immunosuppressive therapies and age, could lead to an increased risk of infection in children and adolescents who are immunocompromised. Lower immunogenicity in these populations. These children may have a poor response to vaccines and therefore require additional doses. Markers such as CD4/CD8 or torque teno virus (TTV) replication could be linked to immunogenicity and thus serve as predictors of efficacy for routine clinical practice.
The risk for Human Papillomavirus (HPV) infection persists through an individual sexual life and duration of protection is critical to vaccine effectiveness in protection from oncogenic hrHPV infection. HIV-infected individuals have an increased risk for HPV infection, and persistent infection. Most vaccine efficacy data among HIV-infected adolescents is represented by immunogenicity data, and there is little published literature on vaccine effectiveness as assessed by persistent incident genital HPV infection. Investigators shall re-enroll a cohort of previously vaccinated HIV-infected girls and boys for assessment of genital HPV infection 9-years post initial 3 doses of vaccination with quadrivalent HPV vaccine at ages 9 to 14 years.
The purpose of this study is to evaluate the immunogenicity and safety of co-immunization with recombinant human papillomavirus bivalent (Types 16,18) vaccine (Escherichia coli) and Hepatitis E vaccine (Escherichia coli)
We propose a cross-sectional study to explore the acceptability and feasibility of HPV self-sampling among Quebec women. The study will invite eligible women to self-sample for HPV at home. The HPV risk factors of patients included in the study will be taken into consideration (vaccination, smoking, number of partners, date of last screening, etc.).
The study will evaluate the immunogenicity and safety of 9-valent HPV recombinant vaccine in Chinese healthy females16 to 26 years of age.
To access the immune persistence of Chinese women aged 9-45 years after receiving quadrivalent HPV vaccine with the immunization schedule of 0, 2 and 6 months.
Take AS04 adjuvanted HPV16/18 vaccine as an example to evaluate the impact of HPV vaccination on HPV infection and related disease burden in the real world based on prospective cohort and Yinzhou Regional Health Information Platform (YRHIP), in order to bridge the gap in relevant evidence in China.
The Pocket colposcope has 510k FDA clearance and has been successfully used in almost 1500 unique patients globally in Duke and non-Duke protocols to date. The objective is to provide colposcopy capability to rural communities in Peru potentially using Telehealth. Approximately 10,000 women will receive self HPV test kit for community health workers. Of these participants, approximately 1,000 HPV+ participants will be invited to participate in this pocket colposcopy study. Approximately 500 of these participants may require treatment using thermocoagulation.
Poor quality of primary care providers' vaccine recommendations lead to low adolescent human papillomavirus vaccination rates and hundreds of thousands of adolescents unnecessarily at risk for HPV-associated cancers and diseases. Though a previous provider communication intervention, called PCOM, was found to be effective for increasing adolescent HPV vaccination in primary care, its dissemination is limited by the need for significant research team involvement to teach providers how to use the intervention's components. To address this, investigators propose to develop and test a virtual version of PCOM, use mixed methods to assess contextual factors affecting its use compared to the original PCOM intervention, and develop an optimized version of PCOM for broad dissemination to increase adolescent HPV vaccination nationally.
