NCT05148559
Vaccine uptake in the United States is lower in rural areas, especially for HPV vaccine. Reminder/recall has been identified as an effective strategy to increase vaccination rates. This study will assess the impact by rurality of vaccine reminder notices sent via the parent's preferred method of communication on HPV vaccination among 12 year-old patients in a regional healthcare system.
NCT06535139
There are three main objectives of the protocol. First, we will evaluate the added clinical- and cost- effectiveness of parent-targeted motivational aids (reminder/recall and phone-based MI) alone and when combined with community-targeted healthcare access assistance beyond the effects of clinician-targeted training. Second, we will estimate the differential effectiveness of the implementation strategies by patient-level factors (age, race/ethnicity, sex, distance from home to clinic, social vulnerability). Third, we will measure moderation of implementation strategy effectiveness by clinic-level factors (HPV vaccination priority, resources, clinic visit types, scheduling practices, and implementation success). Within 11 rural North Central Florida counties, we will evaluate the layering of evidence-based implementation strategies that progressively addressing clinician, parent, and healthcare access barriers faced by rural communities on HPV vaccination rates among 9- to 12-year-olds. To best address our main question of whether layering complementary strategies continues to increase effects on HPV vaccination, we will test our hypotheses with a three-arm cluster randomized study design of nested strategies. The proposed nested study design optimizes evaluation, causal inference, and scientific rigor by putting the maximum number of clinics towards addressing the layering of strategies. Randomization will occur at the clinic level. All clinics will receive implementation strategy A: clinician-targeted recommendation training. A random 20 of 30 of clinics will also receive facilitation of parent-targeted motivational aids (B) for an implementation strategy package of A+B. Finally, a random half of the clinics who receive A+B will also receive community-targeted healthcare access (C) for a total implementation strategy package of A+B+C. This equates to a three-arm cluster randomized trial in which 10 clinics receive clinician- targeted recommendation training alone (A), 10 clinics receive clinician-targeted recommendation training and parent-targeted motivational aids (A+B), and 10 clinics receive clinician-targeted recommendation training, parent-targeted motivational aids, and community-targeted healthcare access (A+B+C).
NCT06002282
The objectives of the study are to pilot test a tailored intervention among Black families with adolescents. The hypotheses are that the study protocol will be feasible and messages tailored to parents' needs will increase vaccine confidence and intention to vaccinate.
NCT05266898
The primary objective of this study is to determine the magnitude and breadth of the serum antibody response to the nonavalent HPV vaccine (Gardasil-9) in adults with well-controlled HIV infection. The secondary objectives of the study are to observe short term clinical outcomes of prevalent HPV genotype-specific anogenital infections in adults living with HIV who complete the three-dose Gardasil-9 vaccine series, and to determine the protection afforded by Gardasil vaccine over time in previously vaccinated adults living with HIV. The clinical hypothesis is that adults with virologically controlled HIV mount a serum antibody response to the nonavalent HPV vaccine that is comparable to HIV negative counterparts. We also postulate that HPV vaccination will provide short-term clinical benefit against HPV infections and disease associated with vaccine genotypes and continuing protection against vaccine genotypes of HPV over time.
NCT04180462
Washington University will evaluate the effectiveness of a multi-component implementation strategy to increase use of HPV vaccine in primary care practices.
NCT06854354
Randomized clinical trial with two groups, with a test-retest model, with single-blind approach, using a probabilistic sampling and the population was mothers of girls aged 9 to 12 years from a public elementary school in the state of Puebla. The objective was to determine the effect of the intervention "Vaccine for HPV Prevention" aimed at the acceptance of the HPV vaccine in mothers of girls aged 9 to 12 years old in the urban area of the State of Puebla.
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.
NCT02358083
The purpose of this study was to determine whether messages about 1. relative risk of vaccination vs. other activities and 2. strength of doctor's recommendation influenced parental intention to get own child vaccinated against human papillomavirus (HPV) or Influenza.
NCT00637195
Infection with human papillomavirus (HPV) has been clearly established as the necessary cause of cervical cancer. The current Phase 3b study is designed to assess the immunogenicity and safety of a commercially available vaccine co-administered with GlaxoSmithKline Biologicals' HPV vaccine GSK580299 in healthy female subjects.
NCT02370459
The University of North Carolina will test the effectiveness of the Centers for Disease Control and Prevention's AFIX model for increasing HPV vaccination coverage among adolescents. AFIX (Assessment, Feedback, Incentives and eXchange) consists of brief quality improvement consultations that immunization specialists from state health departments deliver to vaccine providers in primary care settings. Using immunization registry data, the specialist evaluates the clinic's vaccination coverage and delivers education on best practices to improve coverage. We will compare changes in HPV vaccination coverage before and after consultations for high-volume pediatric and family medicine clinics across three study conditions: traditional consultations (in-person group), virtual consultations (webinar group), or no consultations (control group). In each participating state, 30 clinics will be randomly assigned to each study arm, for a total of 90 clinics per state, or 270 clinics overall. The primary objective of this study is to compare the change in coverage for HPV vaccine initiation among 11-12 year old patients, from baseline to 6-month follow-up. Secondarily, we will compare the change in coverage for other vaccines and age groups.
