Summary

This trial tests whether an AI-powered chatbot can improve health literacy about the HPV vaccine among Japanese caregivers of unvaccinated daughters aged 12–18. Participants will either interact with the chatbot or read a standard government leaflet, then complete surveys to measure changes in knowledge and vaccination decisions. The goal is to see if a digital tool can more effectively counter misinformation than traditional written materials.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: An AI-powered chatbot delivering tailored HPV vaccination information
What this could lead to: If effective, this chatbot could become a scalable tool to counter vaccine misinformation and improve HPV vaccination rates among young girls in Japan.
What could go wrong: The trial measures knowledge and decision-making, not actual vaccination uptake. The chatbot's impact may be limited if caregivers already hold strong beliefs or lack internet access.
