MWITA-HCO-2026-006 · Evidence A · P1
A five-week motivational-interviewing AI vaccine assistant improved vaccine readiness and health literacy among vaccine-hesitant Hong Kong adults but did not produce a significant group-by-time reduction in vaccine hesitancy.
What this does not establish
A multicomponent education-plus-chatbot intervention cannot isolate the chatbot effect and does not establish vaccine uptake, disease prevention, or transfer to other vaccines and jurisdictions.
Counterevidence & uncertainty
Readiness and literacy moved without a statistically supported comparative reduction in the primary hesitancy construct.
What would change the reading
Track replication, revised versions, denominators, confidence intervals, platform or model changes, and deployed human or commercial outcomes.
