Paper Information

• Subject Areas: Social Sciences, Public Health, Informatics
• Keywords: COVID-19 vaccine, medical racism, social media, information disorder, misinformation, public health, human computation, vaccine hesitancy, Tuskegee Syphilis Study

Research Background and Issues

• Findings and Challenges:

  • Vaccine hesitancy has long plagued the field of public health, while anti-vaccine movements fueled by misinformation have rapidly expanded over the past 25 years.
  • Historical racism and medical injustice have made vaccine refusal or hesitancy particularly pronounced among Black communities in the United States.
  • During the COVID-19 pandemic, misinformation has deliberately exploited issues of medical racism, especially connections to the Tuskegee Syphilis Study, further undermining vaccine trust.

• Significance of the Issue:

  • Declining vaccine trust directly threatens herd immunity levels, hindering efforts to control the spread of COVID-19.
  • Information disorder not only critically impacts vaccination rates but also transcends boundaries of political, religious, and racial discourse.

• Motivation and Related Work:

  • This study focuses on the social media platform Twitter, using qualitative analysis and contextualization to explore the intersection of misinformation and medical racism in vaccine trust issues.
  • The frequent mention of the Tuskegee Syphilis Study in vaccine mistrust narratives and its co-occurrence with vaccine-related discussions highlight a novel behavior that warrants attention and research.

Proposed Solution

• Proposed Methods:

  • The research team conducted extensive data collection via the Twitter API, filtering vaccine-related discussions linked to the Tuskegee Syphilis Study.
  • Using qualitative coding and network graph analysis, the study extracted polyvocal narratives related to medical racism and vaccine trust.

• Innovative Contributions:

  • The study emphasizes the theoretical framework of polyvocality, analyzing the multifaceted and complex phenomena of social media discussions from multiple perspectives.
  • It distinguishes between various voices and narratives within the "information disorder space," including genuine expressions, misinformation, and deliberate disinformation.

• Implementation Steps and Key Techniques:

  • The data collection phase covered Twitter posts from 2018 to 2021, using search keywords such as "Tuskegee" and vaccine-related terms.
  • Qualitative coding based on content features identified user characteristics (e.g., political stance and racial identity).
  • A network graph of Twitter user interactions was created to analyze the interactions and isolation among different "voices."

Research Findings

• Specific Findings:

  • Identified 12 distinct voices within social media discussions, encompassing vaccine supporters, vaccine-hesitant individuals, and misinformation disseminators.
  • Observed dynamic changes in COVID-19 vaccine discussions: pro-vaccine voices became more consolidated during the pandemic, while tensions with vaccine-hesitant voices intensified.
  • The Tuskegee Syphilis Study was erroneously linked to vaccination, becoming a central theme in misinformation and false narratives.

• Advantages Over Existing Solutions:

  • Provides an in-depth understanding of the mechanisms of information disorder, distinguishing between genuine concerns and manipulative behaviors in vaccine mistrust expressions.
  • Highlights the responsibility of social media algorithms and platform design in verifying information.

• Experimental and Evaluation Results:

  • Found that vaccine mistrust tweets were shared 1.5 times more frequently than pro-vaccine tweets, demonstrating the rapid spread of misinformation.
  • Network graphs revealed the interactions and branching dynamics between pro-vaccine and anti-vaccine groups.

• Limitations and Future Directions:

  • Limitations: The study focuses on the interaction space formed by specific terms (e.g., Tuskegee + vaccine), which may not fully represent the broader discussion of medical racism on social media.
  • Future Directions: Develop technological tools to support "polyvocal reading," helping researchers and the public better distinguish between genuine concerns and malicious information; introduce platform design frictions to reduce the spread of misinformation.

Conclusion

This study dissects the complex phenomenon of COVID-19 vaccine trust, revealing how information disorder interacts with issues of medical racism through social media channels. It underscores the necessity of addressing misinformation through both human behavior and technological design, while providing a new theoretical framework and empirical support for the critical issue of vaccine trust.
