• Authors: Matheus Schmitz, Goran Muri\'c, Keith Burghardt
• Abstract summary: Anti-vaccine hesitancy has been recently driven by the anti-vaccine narratives shared online. We introduce a Python package capable of analyzing Twitter profiles to assess how likely that profile is to spread anti-vaccine sentiment. We leverage the data on such users to understand what are the moral and emotional characteristics of anti-vaccine spreaders.

• Abstract: Vaccine hesitancy has a long history but has been recently driven by the anti-vaccine narratives shared online, which significantly degrades the efficacy of vaccination strategies, such as those for COVID-19. Despite broad agreement in the medical community about the safety and efficacy of available vaccines, a large number of social media users continue to be inundated with false information about vaccines and, partly because of this, became indecisive or unwilling to be vaccinated. The goal of this study is to better understand anti-vaccine sentiment, and work to reduce its impact, by developing a system capable of automatically identifying the users responsible for spreading anti-vaccine narratives. We introduce a publicly available Python package capable of analyzing Twitter profiles to assess how likely that profile is to spread anti-vaccine sentiment in the future. The software package is built using text embedding methods, neural networks, and automated dataset generation. It is trained on over one hundred thousand accounts and several million tweets. This model will help researchers and policy-makers understand anti-vaccine discussion and misinformation strategies, which can further help tailor targeted campaigns seeking to inform and debunk the harmful anti-vaccination myths currently being spread. Additionally, we leverage the data on such users to understand what are the moral and emotional characteristics of anti-vaccine spreaders.

  Anti-viral therapies are typically designed to target only the current strains of a virus. therapy-induced selective pressures act on viruses to drive the emergence of mutated strains, against which initial therapies have reduced efficacy. We build on a computational model of binding between antibodies and viral antigens to implement a genetic simulation of viral evolutionary escape.

  Vaccine hesitancy continues to be a main challenge for public health officials during the COVID-19 pandemic. We present Vax-Culture, a novel Twitter COVID-19 dataset consisting of 6373 vaccine-related tweets. We hope this can lead to effective and targeted public health communication strategies for reaching individuals with anti-vaccine beliefs.

  This paper presents a classification model for detecting COVID-19 vaccination related search queries. We propose a novel approach of considering dense features as memory tokens that the model can attend to. We show that this new modeling approach enables a significant improvement to the Vaccine Search Insights (VSI) task.

  A substantial proportion of the population is still hesitant to be vaccinated against the COVID-19 virus. Existing datasets fail to cover all these aspects, making it difficult to form a complete picture in inferencing about the problem of vaccine hesitancy. In this paper, we construct a multi-source, multi-modal, and multi-feature online-offline data repository CoVaxNet.

  Administering COVID-19 vaccines at a societal scale has been deemed as the most appropriate way to defend against the COVID-19 pandemic. This global vaccination drive naturally fueled a possibility of Pro-Vaxxers and Anti-Vaxxers strongly expressing their supports and concerns regarding the vaccines on social media platforms. The goal of this work is to improve this understanding using the lens of Twitter-discourse data.

• Classifying vaccine sentiment tweets by modelling domain-specific representation and commonsense knowledge into context-aware attentive GRU [9.8215089151757]
  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.
