About this study

Official title: TweenVax: A Comprehensive Practice-, Provider-, and Parent/Patient-Level Intervention to Improve Adolescent HPV Vaccination

This clinical trial compares the effect of a vaccine promotional intervention, TweenVax, to standard of care vaccination promotion practices on rates of human papillomavirus (HPV) vaccination in adolescents. HPV vaccination has been identified as a priority for cancer prevention and control by the Cancer Moonshot Blue Ribbon Panel, which estimated that increasing HPV vaccination rates can prevent 400,000 HPV-related cancers in the next 5-10 years. The goal is for HPV vaccinations to be completed by the age of 13. It has been estimated that only about 16% of adolescents were fully up to date with HPV vaccines by age 13. Strong and consistent provider recommendations have been shown to play an important role in the uptake of vaccines. In addition, education and information received by parents may improve the strength of recommendations by providers. The TweenVax intervention includes practice, provider, parent and patient level education to teach best practices, help with vaccine messaging, and give correct and easy to understand information to parents. Providing practice, provider and parent level access to TweenVax may be more effective than current vaccine promotion practices in improving HPV vaccination rates in adolescents.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To test the expanded and revised TweenVax intervention package based on pilot study findings and formative research evaluating best practices and deficiencies observed during adolescent healthcare encounters.

OUTLINE: Pediatric practices are randomized to 1 of 3 arms.

ARM I: Practices receive all TweenVax components and trainings related to the practice, provider and staff, parent and adolescent-level intervention. Parents receive access to the TweenVax application and receive TweenVax vaccination information using the provided tablet during clinical encounters on study.

ARM II: Practices receive components and trainings related to the practice and provider-level intervention on study.

ARM III: Practices continue to offer standard of care adolescent vaccination promotion practices to adolescent patients on study.

After completion of study intervention, practices are followed for up to 1 year.

Being tested
Best Practice, Educational Intervention, Health Promotion and Education, Internet-Based Intervention

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Initiation and completion of human papillomavirus (HPV) vaccine by 13 years of age

    Will do a direct comparison of rates in the intervention groups relative to the control group. However, if there is an imbalance in covariates between the arms, will then use multivariable regression, accounting for clinic-level clustering and key covariates. If needed, the initial regression model will be a log-binomial regression, to directly estimate relative risk; however, the final modeling choice will be dependent on the actual distribution of the data which may necessitate an alternative modeling method. Each intervention arm will be compared to the control arm independently, and analysis will be conducted separately for HPV vaccine series initiation and completion. Will model vaccination rates with associated 95% confidence intervals, and comparisons between intervention arms will be conducted by comparing confidence intervals.

    Measured: Up to 1 year follow-up

Secondary outcomes (1)
  1. Rate of missed opportunities for vaccination

    Will assess the total number of healthcare encounters, classifying them as whether the adolescent was eligible for HPV vaccine at the time of the visit. Eligible visits with no vaccine administered, when a vaccine could have been administered based on eligibility, will be considered a missed opportunity. Will compare the mean number of missed opportunities per arm using analysis of variance, and the proportion of adolescents with at least one missed opportunity per arm using Fisher's exact test.

    Measured: Up to 1 year follow-up

Questions about this trial

What is this clinical trial studying?

A study testing Best Practice, Educational Intervention and Health Promotion and Education in people with Human Papillomavirus-Related Carcinoma, run by Emory University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 3 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Robert Bednarczyk, PhD (404-727-9713, rbednar@emory.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Initiation and completion of human papillomavirus (HPV) vaccine by 13 years of age (time frame: Up to 1 year follow-up). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
