Vaccination Debate

This study revisits vaccine discussion in social media before and after the onset of COVID-19. Instead of looking at a short burst of posts, it draws on a long-running Twitter dataset from 2015 to 2021 to examine how vaccine sentiment changed over space and time.

Using supervised machine learning and word embeddings, the project measures pro-vaccine, anti-vaccine, and neutral opinions across the United States. It connects online discourse with vaccination behavior and offers a way to monitor public opinion around vaccination campaigns.
