This mixed-methods study assessed dengue vaccine hesitancy among 429 international travelers in Bangkok, Thailand, from May 2024 to March 2025. The study found that only 36.8% accepted the dengue vaccine, with non-religious affiliation, higher confidence, and lower perceived constraints significantly associated with acceptance. The findings highlight barriers to vaccine uptake that could inform future vaccination strategies.
Key findings
- Dengue vaccine acceptance was only 36.8% among travelers.
- Non-religious affiliation was associated with a higher acceptance rate (aOR: 4.89).
- Non-acceptors reported significantly higher levels of complacency and constraints (p < 0.001).
- Trust in healthcare providers from endemic regions influenced vaccination decisions.
Why it matters
Understanding the barriers to dengue vaccine uptake is crucial for healthcare providers to develop effective strategies that enhance vaccine confidence and address misconceptions about dengue risk, ultimately improving public health outcomes for travelers.
