As progress on vaccine rollout in the United States slowed down in Spring 2021, it became clear that anti-vaccine information posed a public health threat. Using text data from 5,613 distinct COVID misinformation stories and 70 anti-vaccination Facebook groups, we tracked highly salient keywords regarding anti-vaccine discourse across Twitter, thousands of news websites, and the Google and Bing search engines from May through June 2021, a key period when progress on vaccinations very clearly stalled.

Despite ongoing discussion of the need for increased regulation and oversight of social media, as well as debate over the extent to which the platforms themselves should be responsible for containing misinformation, there is little consensus on which interventions work to address the problem of influence operations and disinformation campaigns.

With the outbreak of the coronavirus pandemic came a flood of novel misinformation. Ranging from harmless false cures to dangerous rhetoric targeting minorities, coronavirus-related misinformation spread quickly wherever the virus itself did. Fact-checking organizations around the world took up the charge against misinformation, essentially crowdsourcing the task of debunking false narratives.
