Testing digital messages to help parents vaccinate daughters against HPV

This trial is testing whether different types of digital messages — delivered through phones and other devices — can help parents in Nigeria feel more confident about vaccinating their daughters against HPV, a virus that causes cervical cancer. Researchers will compare five different approaches: an interactive chatbot that talks through vaccine concerns, a game that teaches you to spot false information about vaccines, short educational videos about HPV and vaccination, existing vaccine fact sheets, and unrelated health information. The goal is to find the most effective, affordable way to help parents make decisions about this important vaccine.

Cervical cancer is a leading cause of cancer deaths among women in Nigeria, and HPV vaccination is safe and can prevent it. However, many parents are hesitant, confused, or haven't heard reliable information about the vaccine. This trial is testing whether digital tools delivered through mobile phones — which many people already use — can help overcome these barriers in an affordable, scalable way.
