This study systematically reviews academic research on the relationship between social media and vaccine hesitancy in Türkiye, covering studies published between 2015 and 2024. The research examines the dominant themes, arguments and communication strategies used in anti-vaccine narratives on platforms such as X, Facebook, Instagram, YouTube and Ekşi Sözlük. Findings indicate that misinformation, conspiracy theories, and distrust in health authorities significantly influence vaccine hesitancy. Additionally, anti-vaccine accounts often use social media to amplify their messages through engagement strategies, including viral hashtags and coordinated campaigns. The systematic review identifies six major themes: characteristics of anti-vaccine accounts, the relationship between social media and anti-vaccination, propagated conspiracy theories, anti-vaccine content and claims, sentiments towards COVID-19 vaccines, and key actors in vaccine debates. The study highlights the urgent need for interdisciplinary research to combat vaccine misinformation and proposes strategies such as improving digital health literacy, leveraging social media for pro-vaccine messaging and implementing AI-powered content moderation. Addressing vaccine hesitancy requires a comprehensive communication approach that counters misinformation while fostering trust in health authorities. This study provides a foundation for future research and policy recommendations to mitigate the public health risks associated with online anti-vaccine discourse.}, number={70}, publisher={Ankara Hacı Bayram Veli Üniversitesi}, organization={Destekleyen kurum bulunmamaktadır.}
