In the COVID-19 epidemic, false scientific information spreads fast and causes great harm, which has attracted the attention of scholars. Based on the research results of re-contextualization strategies of scientific discourse, this study explores the rhetoric strategies of the anti-vaccination campaign in the United States. It improves the framework of discourse strategy analysis of science communication, and puts forward suggestions on how to reduce the dissemination of false scientific information.
