This is a randomized observer-blind placebo-controlled proof-of-concept study with the aim to assess the safety and tolerability, and the immunogenicity of a bivalent HPV vaccine administered in healthy infants and toddlers (9- and 15-month-olds) comparing them to an immune-bridging population of 15-20-year-old unmarried females in an open label study in Ghana at the Dodowa Health Research Center.
NCT07525245
This is an interventional study targeting parents of junior high school girls. The primary objective of the study is to evaluate the effectiveness of a vaccine chatbot in improving HPV vaccination rates among parents' junior high school girls. The secondary objectives are to evaluate the effectiveness in improving vaccine awareness and vaccination intention among parents. All participants will be enrolled and randomly assigned to four groups: (1) vaccine chatbot plus scientific videos, (2) vaccine chatbot only, (3) scientific videos only, and (4) a control group (no intervention). The chatbot will provide immediate, validated answers to participants' HPV vaccine-related questions. The scientific videos will cover content related to HPV vaccine safety, efficacy, and other relevant information. The study will compare changes in HPV vaccine awareness, vaccination intention, and vaccination behavior between the intervention groups and the control group after the intervention to evaluate whether the three intervention strategies enhance HPV vaccine awareness, vaccination intention, and vaccination uptake.

NCT07200570
The goal of this clinical trial is to learn if a chatbot powered by artificial intelligence works to improve HPV vaccination among females aged 15 to 26 in China. A randomized controlled trial and implementation science study will be conducted targeting females as participants. The main questions it aims to answer are: 1. Does the vaccine chatbot influence women's confidence, literacy, hesitancy, and uptake of the HPV vaccine. 2. What are the public acceptance of chatbot and the facilitators and barriers to its implementation in a real-world setting. Researchers will compare a group of women who use the chatbot with a group who do not use it to see if the chatbot is effective at helping women feel confident and willing to get vaccinated against HPV. Participants will: 1. Be recruited and randomly allocated into one of two groups. One group will be invited to use the HPV vaccine chatbot and the other group will not get access to the vaccine chatbot until the end of the trial. 2. Complete a questionnaire survey on their confidence, literacy, and hesitancy on the HPV vaccine. 3. Have their vaccination status checked at the end of trial.
NCT06831929

NCT04235257
This randomized phase IV trial compares fractional dose of bivalent HPV vaccine to fractional dose of nonavalent HPV vaccine among men and women aged 27-45 years in Seattle, Washington. Participants will have immune response assessed at baseline, 4 weeks, 6 months, 12 months, and 24 months.
NCT06800456
Human papillomavirus (HPV) is a prevalent sexually transmitted infection linked to nearly all cases (99%) of cervical cancer. Prophylactic HPV vaccination is effective in preventing these cancers, complemented by HPV screening and treatment of precancerous lesions. The World Health Organization (WHO) aims to eliminate cervical cancer by 2030 through focused efforts on vaccination, diagnosis, and treatment. Primary prevention strategies include reducing sexual risk factors and administering prophylactic vaccines. Despite awareness of HPV testing, many women lack understanding of its importance and fail to follow through with screenings and necessary treatments. Overall societal awareness of HPV remains inadequate. Studies reveal disparities in HPV vaccine awareness: while 60.7% of women have heard of the vaccine, only 1% have received it. Awareness varies widely across regions, with Turkey reporting rates from 3.8% to 57%, and vaccine awareness ranging from 2.2% to 74.7% (Özdemir et al., 2020). In the UK, concerns over potential negative results lead many women to defer HPV testing. Health anxiety, defined as interpreting minor symptoms as serious health issues, drives individuals to seek excessive online health information, a phenomenon known as cyberchondria. Studies link cyberchondria with heightened health anxiety, exacerbated by prolonged internet searches. Barriers to HPV screening and vaccination include fear of side effects, lack of information, cost concerns, and anxiety over potential outcomes. While women testing positive for HPV show higher levels of cyberchondria, no direct correlation has been established between cyberchondria severity and HPV awareness or vaccination attitudes in adult women. This summary encapsulates the key findings and insights from the referenced studies on HPV, vaccination, and health anxiety.
NCT06683664
The goal of this implementation research study is to understand whether a package of community-based interventions can increase access to and uptake of the human papillomavirus (HPV) vaccine among very young adolescent girls and boys in the North and Far North Regions of Cameroon. The main questions this study aims to answer are: * Can a package of community-based interventions increase delivery of routine HPV vaccination to boys and girls aged 9-13 in Cameroon's North and Far North Regions? * What is the acceptability, feasibility, cost, and potential for maintenance and scale of an integrated health intervention to deliver routine HPV vaccination in Cameroon? To evaluate the effectiveness of the intervention, researchers will compare HPV vaccination within regions where the new intervention model is being implemented (intervention areas) to regions where the new routine HPV vaccination delivery model is not being implemented (comparison areas) for approximately 1 year before the new intervention model is implemented and for approximately 9 months after the start of implementation to compare changes over time and between intervention and comparison areas. The study will evaluate the effect of the intervention on HPV vaccination delivery using routine health facility data. To understand acceptability, feasibility, implementation, and potential for scale, the study will enroll participants including health officials and providers, adolescents girls receiving HPV vaccination and other services in intervention areas, and their parents/caregivers. The study will be conducted in two phases, with the first phase focused on gathering formative data through interviews with key informants. This data will be used to inform the design of the intervention, which will be implemented and evaluated in phase 2. Only phase 1 of this study protocol has been currently approved. In phase 1, key informant interview participants will be asked to participate in a an interview to discuss HPV vaccination services and their perspectives on how to integrate HPV vaccination within existing community-based and health facility structures and programs. Key informants will include government officials, health program implementers, representatives from non-government organizations working on HPV vaccine delivery, and healthcare providers, as well as community leaders including school and religious leaders.
NCT06405048
The primary objective of this survey experiment study is to measure the impact of a mock-up Chinese fact-checking extension on the ability to dispel HPV and HPV vaccine-related misinformation among parents of middle school girls in China.
NCT03399396
The central goal of this study is to identify the optimal approach to implementing an evidence-based practice facilitation (PF) intervention for the uptake and completion of HPV vaccine among adolescents receiving care in the community, guided by implementation science theory. AIM 1: Determine the clinical effectiveness and cost-effectiveness of two modalities for delivering a multi-component PF intervention to increase HPV vaccination initiation and completion in community-based pediatric practices. The investigators will compare the traditional In-person Coaching PF modality to a lower-resource Web-Based Coaching PF modality. The primary patient outcome is HPV vaccination. The investigators will also examine and compare the sustainability of practice changes on vaccination rates and the effects over time for each intervention modality. AIM 2. Understand mechanisms of why the PF intervention may work better for some pediatric practices than others for HPV vaccination. The investigators will examine theory-based determinants at the organizational, provider, and patient levels that may mediate (explain) or moderate (change) the effects of the PF intervention on vaccination outcomes.
NCT04766164
The study will provide important insight into current HPV vaccine knowledge/awareness, health beliefs, affect, vaccine discussions, decision preparedness, and vaccine intentions and behaviors among those ages 18-45, while examining potential differences in responses between those ages 18-26 and those ages 27-45 and vaccinated and unvaccinated individuals.
NCT01276184
Human papillomavirus (HPV) is the most common sexually transmitted disease among adolescent females in the United States. Our primary objective is to determine if Short Message Service (SMS) text message reminders increase adherence to the recommended 3 dose schedule for Gardasil compared to usual care in an outpatient clinic setting. Secondary objectives of this study are: 1) to demonstrate the feasibility of using SMS text message reminders to increase adherence with Gardasil vaccination; and 2) to assess satisfaction and acceptability of text message reminders compared to telephone reminders among women who receive the text message arm of the intervention. The investigators hypothesize that receiving SMS text message reminders will increase adherence to the recommended 3 dose schedule for Gardasil compared to usual care.
