This article analyzes the media coverage of the COVID-19 vaccine by major media outlets in five Latin American countries: Argentina, Colombia, Chile, Mexico, and Peru. For this purpose, the XLM-roBERTa model was applied and the sentiments of all tweets published between January 2020 and June 2023 ( = 24,243) by the five outlets with the greatest online reach in each country were analyzed. The results show that the sentiment in the overall media and in each nation studied was mostly negative, and only at the beginning of the pandemic was there some positivity. In recent months, negative sentiment has increased twelvefold over positive sentiment, and has also garnered many more interactions than positive sentiment. The differences by platform and country are minimal, but there are markedly negative media, some more inclined to neutrality, and only one where positive sentiment predominates. This paper questions the role of journalism in Latin America during a health crisis as serious as that of the coronavirus, in which, instead of the expected neutrality, or even a certain message of hope, the media seem to have been dragged along by the negativity promoted by certain discourses far removed from scientific evidence.
本文分析了阿根廷、哥伦比亚、智利、墨西哥和秘鲁这五个拉丁美洲国家主要媒体对新冠疫苗的报道。为此，应用了XLM-roBERTa模型，并分析了每个国家网络影响力最大的五家媒体在2020年1月至2023年6月期间发布的所有推文（共24243条）的情绪。结果表明，总体媒体以及所研究的每个国家的情绪大多为负面，仅在疫情初期存在一些积极情绪。近几个月来，负面情绪比积极情绪增加了12倍，并且获得的互动也比积极情绪多得多。不同平台和国家之间的差异很小，但存在明显负面的媒体，有些更倾向于中立，只有一家媒体以积极情绪为主导。本文质疑在像新冠病毒这样严重的健康危机期间拉丁美洲新闻业的作用，在这场危机中，媒体似乎被某些远离科学证据的负面言论所左右，而没有达到预期的中立，甚至没有传达某种希望的信息。
