An analysis of science communication about COVID-19 vaccination in Portuguese online news media

Abstract

This study aimed to analyze the usage of scientific concepts and technical terms related to COVID-19 vaccination in Portuguese online news sources and examine citizens' comprehension of these terms. A retrospective descriptive study was conducted, examining Portuguese news articles about COVID-19 vaccination from November 2021 to January 2022. Scientific terms were extracted from 190 articles, and seven citizens provided identification and brief definitions of familiar terms. Approximately 68% of the news articles involved collaboration with researchers or health professionals. A total of 144 scientific terms were identified in 77% of the articles, with more than half (57.54%) of these terms being unknown or inadequately defined by the citizens consulted.
