Temporal Trends in COVID-19 Vaccine Acceptance in Türkiye: A Systematic Review

Background: Determining temporal trends in vaccine hesitancy could provide critical information for fighting against vaccine hesitancy and the pandemic. This paper aims to determine the temporal trends in COVID-19 vaccine acceptance in Türkiye and to assess the relevance of these trends to political decisions and practices. Methods: This systematic review was registered in PROSPERO. Studies published in TRDizin, DergiPark, PubMed, Web of Science, and the National Thesis Center databases were examined. The final article search was conducted on 20.05.2022. Results: This review contains 51 studies (n=52421). Until the date when Türkiye (Ministry of Health) announced that Türkiye had an agreement with a vaccine company, COVID-19 vaccine acceptance was in a decreasing trend; after that it turned into an increasing trend. Conclusion: As a result, we concluded that the periodic decrease in vaccine acceptance was related to information pollution, vaccines’ uncertainties, and health communication issues during the relevant time period.
