To evaluate the impact of a web-based Japanese Encephalitis vaccine decision aid (JEVaDA) on informed vaccine decision-making and vaccine uptake among Australian travelers compared to a standard government information resource.
Key Findings:
The JEVaDA significantly reduced decisional conflict compared to the government information resource.
Participants using the JEVaDA showed improved knowledge about JE and higher intention to vaccinate.
Self-reported vaccine uptake was assessed approximately 2 months after the planned trip.
Interpretation:
Limitations:
The study may not generalize to all traveler demographics outside the Australian context.
Self-reported data may introduce bias in vaccine uptake reporting due to reliance on participant honesty and recall.
