- Abstract: The recent vaccine-related infodemic has amplified public concerns, highlighting the need for proactive misinformation management. We describe how we enhanced the reporting surveillance system of Victoria's vaccine safety service, SAEFVIC, through the incorporation of new information sources for public sentiment analysis, topics of discussion, and hesitancies about vaccinations online. Using VaxPulse, a multi-step framework, we integrate adverse events following immunisation (AEFI) with sentiment analysis, demonstrating the importance of contextualising public concerns. Additionally, we emphasise the need to address non-English languages to stratify concerns across ethno-lingual communities, providing valuable insights for vaccine uptake strategies and combating mis/disinformation. The framework is applied to real-world examples and a case study on women's vaccine hesitancy, showcasing its benefits and adaptability by identifying public opinion from online media.

We introduce the first multilingual Event Extraction framework for extracting epidemic event information for a wide range of diseases and languages.
Annotating data in every language is infeasible; thus we develop zero-shot cross-lingual cross-disease models.
Our framework can provide epidemic warnings for COVID-19 in its earliest stages in Dec 2019 from Chinese Weibo posts without any training in Chinese.

With the rollout of vaccination campaigns, German-speaking regions exhibited much lower vaccination uptake than other European regions.
We show that skepticism regarding the severity of the COVID-19 virus and towards efficacy and safety of vaccines were among the prevalent topics in the discourse on Twitter.
During later phases of the pandemic, when implemented policies restricted the freedom of unvaccinated citizens, increased vaccination uptake could be observed.

We develop a framework to extract and analyze epidemic-related events from social media posts.
Experimentation reveals how ED models trained on COVID-based SPEED can effectively detect epidemic events for three unseen epidemics.
We show that reporting sharp increases in the extracted events by our framework can provide warnings 4-9 weeks earlier than the WHO epidemic declaration for Monkeypox.

among Healthcare Workers [64.1526243118151]
We find that doctors are overall more positive toward the COVID-19 vaccines.
Doctors are more concerned with the effectiveness of the vaccines over newer variants.
Nurses pay more attention to the potential side effects on children.

We analyze 6 years of Italian vaccine debate across diverse social media platforms (Facebook, Instagram, Twitter, YouTube)
We first use the symbolic transfer entropy analysis of news production time-series to determine which category of sources, questionable or reliable, causally drives the agenda on vaccines.
We then leverage deep learning models capable to accurately classify vaccine-related content based on the conveyed stance and discussed topic.

We leverage the textual posts on social media to extract and track users' vaccination stances in near real time.
We integrate the recent posts of a user's social network neighbours to help detect the user's genuine attitude.
Based on our annotated dataset from Twitter, the models instantiated from our framework can increase the performance of attitude extraction by up to 23%.

Vaccine hesitancy and refusal can create clusters of low vaccine coverage and reduce the effectiveness of vaccination programs.
Social media provides an opportunity to estimate emerging risks to vaccine acceptance by including geographical location and detailing vaccine-related concerns.
Methods for classifying social media posts, such as vaccine-related tweets, use language models (LMs) trained on general domain text.
We present a novel end-to-end framework consisting of interconnected components that use domain-specific LM trained on vaccine-related tweets and models commonsense knowledge into a bidirectional gated recurrent network (CK-BiGRU) with context-aware attention.

We examine the extent to which the vaccination debate on Twitter is conductive to potential outreach to the vaccination hesitant.
We discover that the vaccination skeptics, as well as the advocates, reside in their own distinct "echo chambers"
At the center of these echo chambers we find the ardent supporters, for which we build highly accurate network- and content-based classifiers.
