Area Of Science
- Health Communication
- Vaccinology
- Qualitative Research
Background
- The language used to discuss health conditions can impact vaccine acceptance.
- Understanding parental perceptions of vaccine mechanisms is crucial for effective health messaging.
- This study explores metaphors Brazilian parents use to describe vaccine function.
Purpose Of The Study
- To qualitatively analyze the metaphors Brazilian parents employ to explain how vaccines work.
- To identify which metaphorical frameworks are most prevalent in understanding vaccine mechanisms.
Main Methods
- Cross-sectional online survey conducted in Brazil (November 17 - December 14, 2021).
- Participants (15,297 caregivers) selected from predefined metaphors or provided open-ended responses.
- Qualitative analysis of open-ended responses using Iramuteq software, based on conceptual metaphor theory.

- Qualitative analysis of 687 open-ended responses provided further insights into metaphorical understanding.
Conclusions
- Metaphors are powerful tools for enhancing vaccine adherence.
- The choice and impact of metaphors can be culturally and regionally specific.
