Can a tablet app get more kids vaccinated against Cancer-Causing HPV?
NCT ID NCT03429413
First seen Sep 14, 2026 · Last updated Sep 15, 2026 · Updated 1 time
Summary
HPV vaccines can prevent thousands of cancer cases each year, but many children do not get them. Researchers at the University of Florida test whether a tablet app called Protect Me 4 helps parents and doctors talk about the vaccine and decide to give it. The trial enrolls parents of 11-12 year olds and their providers at clinics, comparing clinics that use the app plus quality-improvement support with those that do not. The main goal is to see if the app is practical to use and whether it increases the first dose of the HPV vaccine.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a tablet app called Protect Me 4 that guides parents and providers through HPV vaccine conversations, plus clinic quality-improvement support
- What this could lead to
- If the app works, clinics could use it to raise HPV vaccination rates and prevent cancers linked to the virus.
- What could go wrong
- This is a feasibility trial, so it mainly checks whether clinics can use the app as planned, not whether it prevents cancer. App-based reminders may not change vaccination behavior outside these clinics.
