What is the purpose of this trial?

This trial tests new methods to encourage HPV vaccination among parents and caregivers of children aged 9-17 in rural communities. The study explores automated reminders, some with additional follow-ups, to boost vaccine rates and reduce cancer risks linked to HPV in these areas. Participants will join one of three groups: automated reminders, automated reminders with additional prompts, or usual care with standard reminders. This trial is ideal for English or Spanish-speaking parents or caregivers whose children are eligible for HPV vaccination and have visited a participating clinic in the past year. As an unphased trial, this study provides a unique opportunity to contribute to innovative strategies that could enhance public health in rural communities.

Do I need to stop my current medications to join the trial?

The trial information does not specify whether you need to stop taking your current medications. It seems focused on promoting HPV vaccination, so it's unlikely that your current medications would be affected.

What prior data suggests that the PREVENT intervention is safe for increasing HPV vaccination?

Research has shown that methods like those in the PREVENT study have been used safely in the past. For instance, sending reminders through automated calls, texts, or emails has increased vaccination rates without causing harm. Studies have found these methods to be well-tolerated, with no negative effects reported.

The HPV vaccine has been monitored for over 15 years and is proven safe and effective. Most side effects are mild, such as a sore arm at the injection site.

In this trial, both the Automated Intervention and the Automated Intervention Plus employ similar reminder methods. These approaches are neither new nor risky and aim to increase vaccination rates by keeping families informed and engaged. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the PREVENT intervention for increasing HPV vaccination because it employs innovative communication strategies that standard care typically doesn't use. The "Automated Intervention" arm uses automated messages via phone, text, or email, incorporating engaging elements like text-linked videos and patient narratives to motivate vaccination. The "Automated Intervention Plus" arm builds on this by adding live phone calls or patient navigation for those who don't get vaccinated promptly, using tailored materials from trusted health organizations. These proactive and personalized approaches aim to significantly boost vaccination rates compared to the usual care, which relies on passive reminders during clinic visits or electronic health records.

What evidence suggests that the PREVENT intervention could be effective for increasing HPV vaccination rates?

Research has shown that automated strategies can significantly increase HPV vaccination rates. One study found a 28% rise in starting the HPV vaccine series among participants using these methods. Additionally, about 70% of studies employing these strategies reported noticeable increases in vaccination rates, ranging from 12.5% to 65.5%. In this trial, participants in the Automated Intervention arm will receive automated reminders, while those in the Automated Intervention Plus arm will receive both automated reminders and personal prompts. The Automated Intervention Plus approach, which combines automated reminders with personal prompts, is considered a promising way to boost vaccine uptake, especially when healthcare providers strongly recommend it. These findings suggest that both automated and enhanced communication strategies can effectively encourage HPV vaccination in various communities. ^{1 3 6 7 8}

Are You a Good Fit for This Trial?

This trial is for parents and caregivers of children aged 9-17 living in rural areas of the Mountain West who are hesitant about or have refused HPV vaccination. Participants will help test strategies to increase vaccine uptake.

Trial Overview

The PREVENT program aims to boost HPV vaccination rates through tailored clinic-based outreach. It involves a randomized controlled trial where participants receive interventions at different times, plus interviews for feedback.

How Is the Trial Designed?

Group I: Automated Intervention Plus (Auto-Plus) Experimental Treatment 1 Intervention

Auto-Plus intervention participants will be eligible for automated reminders, plus additional P/C prompts for patients who do not undergo vaccination within three weeks. These prompts may be delivered via live phone call outreach or patient navigation. Activities selected from a list of possible options from the National HPV Vaccination Roundtable and our ranking of the effectiveness of language- and culturally-tailored intervention materials.

Group II: Automated Intervention (Auto) Experimental Treatment 1 Intervention

Auto intervention participants will be eligible for outreach delivered using automated phone calls, text, or email messages with the mode, frequency, timing of reminders, and message content. Automated outreach may also include innovative communication strategies, such as text-linked videos, P/C, or patient narratives. Auto outreach to P/C will invite P/Cs to attend free HPV vaccination visits and emphasize family-friendly hours.

Group III: Usual Care (UC) Active Control 1 Intervention

The UC group will not receive tailored reminders but will only receive opportunistic vaccine reminders that are delivered during clinic visits or MyChart EHR-based patient portal reminders.

Published Research Related to This Trial

Expanding HPV vaccination to adults, particularly at cervical cancer screening visits for women and during STI consultations for both sexes, could lead to significant reductions in HPV infection rates, with reductions of about 20% for women and even greater reductions (63% for HPV-16 and 84% for HPV-18) when including male vaccination.

The study suggests that while the impact of vaccinating adult women alone is modest, combining vaccination strategies for both genders during key health consultations is a highly efficient approach to improve HPV prevention and reduce the incidence of related cancers.

Public Health Benefits of Routine Human Papillomavirus Vaccination for Adults in the Netherlands: A Mathematical Modeling Study. Matthijsse, SM., Hontelez, JA., Naber, SK., et al.[2018]

A comprehensive analysis of adverse events (AEs) reported to the Vaccine Adverse Event Reporting System (VAERS) identified 3,112 AEs for Cervarix, 31,606 for Gardasil, and 6,872 for Gardasil 9, highlighting the need for ongoing monitoring of vaccine safety.

The study found 46 unique serious adverse events (SAEs) associated with the HPV vaccines, clustered around behavioral, neurological, immune, nervous, and reproductive systems, indicating that while the vaccines are effective, further research is needed to understand the cause-and-effect relationships of these AEs.

OAE-based data mining and modeling analysis of adverse events associated with three licensed HPV vaccines. Zi, W., Yang, Q., Su, J., et al.[2022]

There are three licensed HPV vaccines: bivalent, quadrivalent, and nonavalent, with the nonavalent vaccine introduced in 2014, yet vaccination coverage remains low in many developed countries due to safety concerns.

This review aims to clarify the safety profiles of all three HPV vaccines by summarizing data from both pre- and post-licensure studies, particularly focusing on the newer nonavalent vaccine.

The post-licensure safety profile of HPV vaccines Gardasil and Cervarix was evaluated using data from three sources, including VigiBase and VAERS, confirming that the reported adverse events align with existing safety data.

The analysis showed that the safety profiles of both vaccines are consistent with the information provided in their Summary of Product Characteristics (SPC), indicating that they are safe for public use.

Postlicensure safety evaluation of human papilloma virus vaccines. Labadie, J.[2015]

All three HPV vaccines (bivalent, quadrivalent, and 9vHPV) show high efficacy in preventing infections from specific HPV types and associated high-grade cervical dysplasia in women who have not been previously exposed to HPV.

While the bivalent and quadrivalent vaccines have demonstrated early clinical effectiveness in reducing HPV 16 and 18 prevalence, the overall benefits of HPV vaccination in reducing cervical cancer are still largely theoretical, highlighting the need for large-scale studies to confirm long-term effectiveness.

A total of 3174 adverse events (AEs) were reported in children and adolescents aged 6-17 after receiving the HPV vaccine, with 191 (6%) classified as serious.

While these serious AEs raise concerns, further research is necessary to establish a direct link between these events and the HPV vaccine.
