Abstract：
Early successes in controlling the COVID-19 pandemic have prevented Republic of Korea from implementing a prompt, large-scale vaccine rollout to the public. The influence of traditional media on public opinion remains critical and substantial in Republic of Korea, and there have been heated debates about vaccination in traditional media reports in Korea. Effective and efficient public health communication is integral in managing public health challenges. This study explored media reports on the COVID-19 vaccines during the pandemic in Republic of Korea. 12,399 media news reports from May 2020 to September 2021 were collected. An LDA topic model was applied in order to analyze and compare the topics drawn from each study phase using words from the unstructured text data. Although media reports from before the national vaccination implementation focused on the development and rollout of COVID-19 vaccines, diverse topics were reported without any overlap. After the vaccination rollout, the biggest concern was the side effects of the COVID-19 vaccine. In sum, Republic of Korea\'s major media outlets reported on diverse topics rather than generating a common discourse about topics related to COVID-19 vaccination.
摘要：
在控制COVID-19大流行方面的早期成功阻止了大韩民国实施快速，向公众大规模推广疫苗。在大韩民国，传统媒体对公众舆论的影响仍然至关重要和巨大，在韩国的传统媒体报道中，关于疫苗接种的争论非常激烈。有效和高效的公共卫生沟通是管理公共卫生挑战不可或缺的一部分。这项研究探讨了大韩民国大流行期间有关COVID-19疫苗的媒体报道。收集了2020年5月至2021年9月的12399份媒体新闻报道。应用LDA主题模型以便使用来自非结构化文本数据的单词来分析和比较从每个研究阶段得出的主题。尽管在国家疫苗接种实施之前，媒体报道的重点是COVID-19疫苗的开发和推广，报告了不同的主题，没有任何重叠。接种疫苗后，最令人担忧的是COVID-19疫苗的副作用。总之,大韩民国的主要媒体报道了不同的主题，而不是就与COVID-19疫苗接种相关的主题发表共同的论述。
