Social norms, vaccine confidence, and interpersonal communication as predictors of vaccination intentions: Findings from slum areas in Varanasi, India.

In recent years, India has seen significant improvements in childhood immunization, but rates among the urban poor remain stagnant. Disruptions during COVID-19 pandemic have created further challenges. This paper focuses on how social norms, vaccine confidence, and interpersonal communication independently and jointly affect vaccine intentions among caregivers of infants living in six slum areas in Varanasi, India.

Assessing Message Deployment During Public Health Emergencies Through Social Media: Empirical Test of Optimizing Content for Effective Dissemination.

Background: During an infodemic, timely, reliable, and accessible information is crucial to combat the proliferation of health misinformation. While message testing can provide vital information to make data-informed decisions, traditional methods tend to be time- and resource-intensive. Recognizing this need, we developed the rapid message testing at scale (RMTS) approach to allow communicators to repurpose existing social media advertising tools and understand the full spectrum of audience engagement.

Correction: Twitter and Facebook posts about COVID-19 are less likely to spread misinformation compared to other health topics.

The efficacy of Facebook's vaccine misinformation policies and architecture during the COVID-19 pandemic.

Online misinformation promotes distrust in science, undermines public health, and may drive civil unrest. During the coronavirus disease 2019 pandemic, Facebook-the world's largest social media company-began to remove vaccine misinformation as a matter of policy. We evaluated the efficacy of these policies using a comparative interrupted time-series design.

Fighting the infodemic: the 4 i Framework for Advancing Communication and Trust.

Background: The proliferation of false and misleading health claims poses a major threat to public health. This ongoing "infodemic" has prompted numerous organizations to develop tools and approaches to manage the spread of falsehoods and communicate more effectively in an environment of mistrust and misleading information. However, these tools and approaches have not been systematically characterized, limiting their utility.

: personalized vaccine risk communication.

Introduction: Vaccine hesitancy is a global health threat undermining control of many vaccine-preventable diseases. Patient-level education has largely been ineffective in reducing vaccine concerns and increasing vaccine uptake. We built and evaluated a personalized vaccine risk communication website called in English, Spanish and French (Canadian) for vaccines across the lifespan.

Social network analysis of COVID-19 vaccine YouTube videos in Odisha, India: mapping the channel network and analyzing comment sentiment.

India has reported more than 35 million confirmed cases of COVID-19 and nearly half a million cumulative deaths. Although vaccination rates for the first vaccine dose are quite high, one-third of the population has not received a second shot. Due to its widespread use and popularity, social media can play a vital role in enhancing vaccine acceptance.

Production of vaccination videos in India: learnings from a science-art partnership.

Background: Cross-cultural communication, often conceptualized along culture and language dimensions, is an important issue for collaborative teams that include both scientists and artists. Such teams must balance the standardization needs of rigorous scientific methods, on the one hand, with openness for artistic creativity, on the other. The scientific literature does not provide clear guidance on how to structure such collaborations.

Trusted information sources in the early months of the COVID-19 pandemic predict vaccination uptake over one year later.

Introduction: COVID-19 vaccine uptake has been a major barrier to stopping the pandemic in many countries with vaccine access. This longitudinal study examined the capability to predict vaccine uptake from data collected early in the pandemic before vaccines were available.

Methods: 493 US respondents completed online surveys both at baseline (March 2020) and wave 6 (June 2021), while 390 respondents completed baseline and wave 7 (November 2021) surveys.

Creation, dissemination, and evaluation of videos to promote COVID-19 vaccination in India: A research protocol.

Vaccine hesitancy is one of the greatest challenges to the success of coronavirus disease 2019 (COVID-19) vaccination campaigns. Videos promoting vaccines have a narrow scope focusing solely on facts, and less on the emotional and narrative elements of communication that can be equally persuasive. The role of humor, for example, has remained largely unexplored.

Promoting Vaccination in India through Videos: The Role of Humor, Collectivistic Appeal and Gender.

Vaccination hesitancy is a barrier to India's efforts to control the COVID-19 pandemic. Considerable resources have been spent to promote COVID-19 vaccination, but evaluations of such efforts are sparse. Our objective was to determine how vaccine videos that manipulate message appeal (collectivistic versus individualistic), tone (humorous versus serious), and source (male versus female protagonist) toward vaccines and vaccination.

Twitter and Facebook posts about COVID-19 are less likely to spread misinformation compared to other health topics.

The COVID-19 pandemic brought widespread attention to an "infodemic" of potential health misinformation. This claim has not been assessed based on evidence. We evaluated if health misinformation became more common during the pandemic.

Not just conspiracy theories: Vaccine opponents and proponents add to the COVID-19 'infodemic' on Twitter.

In February 2020, the World Health Organization announced an 'infodemic' -- a deluge of both accurate and inaccurate health information -- that accompanied the global pandemic of COVID-19 as a major challenge to effective health communication. We assessed content from the most active vaccine accounts on Twitter to understand how existing online communities contributed to the 'infodemic' during the early stages of the pandemic. While we expected vaccine opponents to share misleading information about COVID-19, we also found vaccine proponents were not immune to spreading less reliable claims.

Use of a Qualitative Story Deck to Create Scenarios and Uncover Factors Associated with African American Participation in Genomics Research.

To gain a complex understanding of willingness to participate in genomics research among African Americans, we developed a technique specifically suited to studying decision making in a relaxed social setting. The "Qualitative Story Deck," (QSD) is a gamified, structured elicitation technique that allows for the spontaneous creation of scenarios with variable attributes. We used the QSD to create research scenarios that varied on four details (race/ethnicity of the researcher; research goal; biospecimen requested; and institutional affiliation).

Willingness of Black and White Adults to Accept Vaccines in Development: An Exploratory Study Using National Survey Data.

Purpose: Explore acceptability of vaccines in development: cancer, Type II diabetes, Alzheimer's disease, Lyme disease, Ebola, and obesity. Research questions: To what extent does acceptability vary by vaccine type? To what extent does acceptability of vaccines in development vary by race and other key demographics? To what extent are general vaccine hesitancy and key demographics associated with acceptability of vaccines in development?

Design: Cross-sectional online survey administered through GfK's KnowledgePanel in 2015. Analysis completed in 2020.

Adapting and Extending a Typology to Identify Vaccine Misinformation on Twitter.

To adapt and extend an existing typology of vaccine misinformation to classify the major topics of discussion across the total vaccine discourse on Twitter. Using 1.8 million vaccine-relevant tweets compiled from 2014 to 2017, we adapted an existing typology to Twitter data, first in a manual content analysis and then using latent Dirichlet allocation (LDA) topic modeling to extract 100 topics from the data set.

Facebook Pages, the "Disneyland" Measles Outbreak, and Promotion of Vaccine Refusal as a Civil Right, 2009-2019.

To understand changes in how Facebook pages frame vaccine opposition. We categorized 204 Facebook pages expressing vaccine opposition, extracting public posts through November 20, 2019. We analyzed posts from October 2009 through October 2019 to examine if pages' content was coalescing.

"I'm a Little More Trusting": Components of Trustworthiness in the Decision to Participate in Genomics Research for African Americans.

Aims: This study sought to explore the decision to participate in genomics research for African American individuals. Our overall goal was to explore (1) the attributes that significantly contribute to willingness to participate in genomics research; (2) how these attributes are interpreted (what is their meaning?); (3) how trustworthiness is estimated in the decision to participate in research (i.e.
