Objectives: The concept of vaccine hesitancy encompasses multiple views on the subject. However, there has been an increasing polarization of the discourse on vaccine hesitancy leading to the stigmatization of those parents who expressed doubts or concerns regarding vaccination practices. The present study aimed to explore the drivers and consequences of polarized discourses on vaccination in the Portuguese context. This paper is part of a broader study which aims to gain a deeper understanding about the phenomenon of vaccine hesitancy at the European level.
Study design: A qualitative research design was used.
Methods: The sample was comprised of thirty-one Portuguese vaccine hesitant parents who were interviewed. A thematic analysis of the transcribed interviews was performed which allowed us to identify key themes.
Results: The results showed that the labelling of vaccine-hesitant parents as 'anti-vaxxers' along with social media play a crucial role in promoting the polarization of vaccine-related attitudes. The stigmatization of vaccine hesitant parents has a disruptive impact on their social network leading them to search for online platforms where they can exchange vaccines-related information without being discriminated.
Conclusions: The stigma and discrimination experienced by vaccine-hesitant parents stimulated that hesitancy becomes more entrenched. Therefore, pluralism should be used to tailor vaccination promotion campaigns to different targets, promoting its reach and efficacy.
