A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional trial in five European countries tests an AI-driven chatbot designed to counter cognitive biases related to childhood vaccines. Participants are randomized to receive either the chatbot or standard informational materials, and complete a large survey to measure vaccine attitudes, confidence, trust, and information exposure. The primary outcome is the ability of parents to distinguish true from false statements about vaccines. The study scales a prior single-country effort to 5,000 participants to assess engagement, behavioral responses, and system performance across diverse settings.
