Abstract

This paper studies the collocates of relational processes in sessions of Câmara dos Deputados (Brazilian National Parliamentary) in which the lemma ‘vacina’ (vaccine) was discussed during the COVID-19 pandemic between 2020 and 2021. Brazil has historically a noteworthy immunisation programme, implemented and maintained by SUS (Sistema Único de Saúde/Unified Health System) which has, in the last few years, faced some challenges, resulting in a decrease in child and adult vaccination. The focus is how the ideological use of the vaccination took the debates in Câmara dos Deputados, in order to analyse whether different political stances may represent different language use and patterns. The corpus was compiled using Python scripts, and it is part of a larger Brazilian political language corpus (BrPoliCorpus). The corpus is structured in speeches from parties that endorse and those who opposed the political views of the Brazilian President at the time. The study analysed the collocates and their statistical significance, followed by a qualitative analysis based on Systemic-Functional Linguistics approach. The results show ideological polarisation in the discourse regarding vaccination.

COVID-19期间巴西葡萄牙语议会话语中的疫苗和疫苗接种：相关过程分析

本文研究了2020年至2021年COVID-19大流行期间巴西国民议会各届会议中相关进程的搭配，其中讨论了引语“疫苗”（vaccine）。巴西历史上有一个值得注意的免疫规划，由SUS （Sistema Único de Saúde/统一卫生系统）实施和维护，在过去几年中，该规划面临一些挑战，导致儿童和成人疫苗接种率下降。重点是疫苗接种的意识形态使用如何在 mara dos Deputados辩论中引起争论，以分析不同的政治立场是否可能代表不同的语言使用和模式。该语料库是使用Python脚本编译的，它是一个更大的巴西政治语言语料库（BrPoliCorpus）的一部分。语料库是由支持和反对当时巴西总统政治观点的政党的演讲构成的。本研究分析了这些搭配及其统计意义，并基于系统功能语言学的方法进行了定性分析。研究结果表明，在关于疫苗接种的论述中存在意识形态的两极分化。
