40 minutes for talk & 20 minutes for discussion How has public discourse changed on Twitter over the COVID-19 pandemic? This talk will offer two case studies: the first on #MyBodyMyChoice, a hashtag originally created to advocate for women's rights but that has now drifted towards conversations around Covid-19, and the second on how advocates for Black maternal health changed the focus of their tweets over the pandemic. co-presented by Diana Grigsby, Justin Uhr, Shahrzad Haddadan, Bjorn Sandstede
