  Retracted scientific articles about COVID-19 vaccines have proliferated false
claims about vaccination harms and discouraged vaccine acceptance. Our study
analyzed the topical content of 4,876 English-language tweets about retracted
COVID-19 vaccine research and found that 27.4% of tweets contained
retraction-related misinformation. Misinformed tweets either ignored the
retraction, or less commonly, politicized the retraction using conspiratorial
rhetoric. To address this, Twitter and other social media platforms should
expand their efforts to address retraction-related misinformation.
