About this trial
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.

Trial outcomes
Primary outcomes
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.
Secondary outcomes
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.
