Patriotism and collectivism have played an essential role in promoting the public to actively take preventive measures and vaccinate against the COVID-19 epidemic in China. Previous related studies were mainly conducted through questionnaires, which has led to a lack of understanding of how this spirit dominates people's epidemic prevention behavior in the natural state. The article focuses on "the mainstream discourse of vaccination in public opinion". Using the method of frame analysis, this paper summarizes the frameworks of COVID-19 vaccines on Sina Weibo and discusses the cultural factors behind them. Through open coding, the research outlines eight frameworks about the topic of COVID-19 vaccines on Sina Weibo-magic weapon, risk, urgent need, long march, solidarity is the power, national achievement, the community of destiny, and political struggle, which account for 79.5% of the sample. We also found that pandemic related mainstream discourse tends to construct the personal experience or attitude of the COVID-19 vaccination from a macro perspective on Sina Weibo; "collectivism" and "patriotism" are the most distinctive features of Weibo discourse. These characteristics of discourse provide new ideas for science popularization and social mobilization of public health emergencies and an even broader field of health advocacy.
