The use of metaphors to construct crisis discourses in describing COVID-19 vaccines in the Chinese and the American news media

There have been limited studies comparing Chinese and American news media in their descriptions of vaccines, especially their use of metaphors in the context of COVID-19. Hence, this paper employs a corpus-assisted critical approach to examine the metaphors used in constructing crisis discourses relating to vaccines in Chinese and American newspapers. The study reveals four conceptual metaphors: WEAPON, MACHINE, TRAVELLER, and CONTEST. The usage of these metaphors is intertwined with wider discursive contexts, which are shaped by the two countries' distinct journalistic and geopolitical/sociocultural contexts. These have resulted in the adoption of different strategies for handling the COVID-19 crisis, reflecting the ideologies of collectivism in China and capitalism in America. The study highlights the significance of metaphors in shaping the ideologies of governments and/or the public towards vaccines through news media. Additionally, this paper provides a useful framework for comparing metaphor usage in two large corpora using Wmatrix.
