Exploring COVID-19 Vaccine Hesitancy Through Topic Modeling: A Systematic Literature Review

The spotlight on Vaccine Hesitancy has intensified since the onset of the Covid-19 pandemic in 2020. This issue involves crucial aspects such as assessing vaccine efficacy, safety, effectiveness, and potential side effects. While past studies have provided an overview of Covid-19 vaccine hesitancy, advancing research in this area requires a systematic review using topic modeling. This study's primary goals are two-fold: first, to recognize and examine the approaches and strategies employed in prior research for shaping discussions on vaccine hesitancy-related subjects. Second, to document the topics identified in specific geographic or country contexts, thereby providing a basis for future research that compares the results. This research utilizes the systematic literature review (SLR) method using proven framework proposed by Kitchenham. Through this SLR approach, we outline various studies related to Vaccine Hesitancy, collect and analyze the methods and techniques used in previous studies, and compile a list of identified topics. The study's outcomes emphasize the intricate nature of Covid-19 vaccine hesitancy and its significant worldwide consequences. This study describes the different modeling and data analysis methods used to explore the topic of vaccine hesitancy. Additionally, the topics identified in different countries or regions may provide valuable insights for follow-up research comparing the influence of geographic context on Vaccine Hesitancy. This research contributes to a deeper understanding of Vaccine Hesitancy and provides an important reference source for future research and policy efforts to overcome vaccination challenges in the Covid-19 pandemic.
