From Pro, Anti to Informative and Hesitant: An Infoveillance study of COVID-19 vaccines and vaccination discourse on Twitter
CoRR(2024)
摘要
COVID-19 pandemic has brought unprecedented challenges to the world, and
vaccination has been a key strategy to combat the disease. Since Twitter is one
of the most widely used public microblogging platforms, researchers have
analysed COVID-19 vaccines and vaccination Twitter discourse to explore the
conversational dynamics around the topic. While contributing to the crisis
informatics literature, we curate a large-scale geotagged Twitter dataset,
GeoCovaxTweets Extended, and explore the discourse through multiple
spatiotemporal analyses. This dataset covers a longer time span of 38 months,
from the announcement of the first vaccine to the availability of booster
doses. Results show that 43.4
phrases and keywords related to vaccines and vaccinations, were unrelated to
the COVID-19 context. In total, 23.1
vaccinations were classified as Pro, 16
as Informative. The trend shifted towards Pro and Informative tweets globally
as vaccination programs progressed, indicating a change in the public's
perception of COVID-19 vaccines and vaccination. Furthermore, we explored the
discourse based on account attributes, i.e., followers counts and tweet counts.
Results show a significant pattern of discourse differences. Our findings
highlight the potential of harnessing a large-scale geotagged Twitter dataset
to understand global public health communication and to inform targeted
interventions aimed at addressing vaccine hesitancy.
