Editorial.

Almost a year later, even as highly effective vaccines against COVID-19 have been developed and deployed, the pandemic continues to throw into high relief the many disparities among people and communities that exist in all societies and across the planet. Since early 2020, we have witnessed vaccine denial, violent protests and inequitable vaccine distribution, with online platforms and social media in the thick of it.

Syn looks at information dissemination and communication strategies on social media by an organization that was central in health information: the United States Centers for Disease Control (CDC). The astonishing rapidity with which scientific publications and data were reviewed and disseminated and the sharing of information resulted in a large body of the literature that turned out to be crucial in tackling the pandemic (even as the pandemic exposed numerous problems in the scholarly communication process).
