A Plan-Do-Study-Act Framework for Adaptive Vaccine Messaging Using Artificial Intelligence

The Plan-Do-Study-Act (PDSA) cycle is a trusted framework for refining public health initiatives. Given rising vaccination hesitancy, we propose an artificial intelligence (AI)-enabled PDSA framework for adaptive vaccine messaging, leveraging social media data. We conducted a literature review, developed the framework and performed a pilot evaluation using Reddit data. Proposed framework: (1) <i>Plan</i> - AI analysis of social media discourse; (2) <i>Do</i> - AI-assisted, tailored messaging creation; (3) <i>Study</i> - assess sentiment and behaviour change; and (4) <i>Act</i> - refine and adapt messaging. This approach leverages social media and AI to develop tailored vaccine communications that continuously evolve based on public needs.
