Abstract
In late 2020, the large-scale rollout of COVID-19 vaccines to combat the global pandemic ignited a firestorm of debates and media discourse on vaccines. We conducted a discourse analysis of tweets (n = 875) criticizing the COVID-19 vaccination process and/or containing negative vaccine information (NVI) authored by influential Twitter accounts receiving the highest user engagement. Results showed news media and private citizens to be important influencers of NVI discourse criticizing the COVID-19 vaccination process on Twitter. The most frequently expressed beliefs centered around ineffective vaccine policies and inadequate government responses. A content analysis revealed that on average, tweets criticizing a broader inadequate public health response were the most retweeted. Statistically significant differences in vaccine discourse were found between Canada and the United States, underscoring the importance of local context-specific factors that influence how Twitter users construct issues related to COVID-19 vaccination. Our results suggest that satisfaction with the leaders in charge of the rollout of COVID-19 vaccines may have depended more on how those leaders acted rather than actual vaccination rates. Studying concerns and criticisms toward vaccination and NVI are key to identifying areas of change in vaccine policies and programs that citizens and other actors want to see implemented.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
