What this trial studies

This clinical trial aims to enhance vaccine information literacy and confidence among individuals in Southeast Asia's Nusantara sociocultural sphere by utilizing a co-created 'prebunking' video. The study involves engaging representatives from Brunei, Indonesia, Malaysia, and Singapore to develop a culturally relevant video that addresses common vaccine misinformation tactics. Participants will be randomly assigned to watch either the intervention video or a control video about safe medication disposal. The effectiveness of the intervention will be evaluated through an online randomized controlled trial.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 18 and older who live in Brunei, Indonesia, Malaysia, or Singapore and are fluent in Bahasa Melayu or Bahasa Indonesia.

Not a fit: Patients who have participated in the design workshops or focus groups, or those with difficulties engaging with social media content, may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly improve vaccine literacy and confidence among populations in Southeast Asia, leading to better public health outcomes.

How similar studies have performed: While the approach of using culturally-specific video interventions is innovative, similar studies have shown promise in improving health literacy and confidence in other contexts.
