This study gives a corpus-assisted discourse study of the representations of the safety and efficacy of COVID-19 vaccines in three representative newspapers from the US, Hong Kong, and the Chinese mainland: New York Times (NYT), South China Morning Post (SCMP), and China Daily (CD). The primary purpose is to explicate the dynamics between vaccines, media, and politics. Combining the theories and methods of critical discourse analysis and corpus linguistics, this study has revealed their preferential ways of constructing the safety and efficacy of COVID-19 vaccines at different levels of discourse.

Although the number of studies on OMC has increased substantially, few provide a comprehensive and up-to-date review of OMC's research constituents, themes, and trends. This study, therefore, extracted 1,801 OMC-related articles published in English from the Web of Science (WoS) Core Collection database during the past 30 years and employed a bibliometric analysis of WoS and CiteSpace to examine major constituents' distribution, collaboration relationships, themes, and trends.

There is a growing need for the public to interact with pediatricians through social media in China, and genuineness is a crucial factor contributing to effective communication, but few studies have examined the relationship between genuineness and its effect on public engagement. This study developed a four-dimension framework including self-disclosure, genuine response, functional interactivity, and genuineness in Chinese culture to investigate the effect of genuineness in the communication of Chinese social media influencers in pediatrics on public engagement. Content analysis was employed to examine these dimensions and the related public engagement in 300 social media posts on the largest microblogging site in China.
