"This review aims to synthesize the global evidence on misinformation related to COVID-19 vaccines, including its prevalence, features, influencing factors, impacts, and solutions for combating misinformation. We performed a systematic review by searching 5 peer-reviewed databases (PubMed, Embase, W ... eb of Science, Scopus, and EBSCO). We included original articles that investigated misinformation related to COVID-19 vaccines and were published in English from January 1, 2020, to August 18, 2022 [...] Of the 8864 studies identified, 91 observational studies and 11 interventional studies met the inclusion criteria. Misinformation around COVID-19 vaccines covered conspiracy, concerns on vaccine safety and efficacy, no need for vaccines, morality, liberty, and humor. Conspiracy and safety concerns were the most prevalent misinformation. There was a great variation in misinformation prevalence, noted among 2.5%-55.4% in the general population and 6.0%-96.7% in the antivaccine/vaccine hesitant groups from survey-based studies, and in 0.1%-41.3% on general online data and 0.5%-56% on antivaccine/vaccine hesitant data from internet-based studies. Younger age, lower education and economic status, right-wing and conservative ideology, and having psychological problems enhanced beliefs in misinformation. The content, format, and source of misinformation influenced its spread. A 5-step framework was proposed to address vaccine-related misinformation, including identifying misinformation, regulating producers and distributors, cutting production and distribution, supporting target audiences, and disseminating trustworthy information. The debunking messages/videos were found to be effective in several experimental studies." (Abstract) more

"WeChat, launched in 2011, has rapidly become the most favoured Chinese social media. Globally available, equally popular both inside and outside China and widely adopted by Chinese migrants, WeChat has fundamentally changed the ways in which Mandarin-speaking migrants conduct personal messaging, en ... gage in group communication and community business activities, produce and distribute news, and access and share information. This book explores a wide range of issues connected to the ways in which WeChat works and is used, across the world among the newest members of the Chinese diaspora. Arguing that digital/social media afford a great degree of individual agency, as well as a collective capacity for sustaining an 'imagined community', the book shows how WeChat's assemblage of infrastructure and regulatory frameworks, technical capabilities, content and sense of community has led to the construction of a particular kind of diasporic Chinese world, at a time marked both by China's rise, and anxiety about Chinese influence in the West."
