“…In addition, perceptions of user profiles and the messages they share are likely to depend on other source characteristics, such as trustworthiness and competence (e.g., Pornpitakpan, 2004) or partisan identity (e.g., Cohen, 2003). Reactions may also be dependent on message characteristics such as evidence format/quality, stance, and familiarity (Hample & Hample, 2014;Jiménez et al, 2018;Lachapelle et al, 2014;Major & Coleman, 2012;Schwarz & Jalbert, 2020);…”

Who is perceived to be an expert on COVID-19 vaccination on social media? We conducted two experimental studies investigating how the presence of biomedical credentials on social media profiles impacts users’ perceived expertise. Participants (Experiment 1 N = 200; Experiment 2 N = 201) viewed a series of Twitter profiles that appeared with or without biomedical credentials and judged to what extent they believed each user was an expert on the topic of COVID-19 vaccination. We found that the presence of biomedical credentials consistently increased perceptions of expertise, including among unvaccinated, vaccine-hesitant, and conservative participants. This work supports existing observations that biomedical credentials may be leveraged by both pro- and anti-vaccine communities to increase perceived credibility and message reach, and counters the narrative that those with anti-vaccination attitudes do not recognize biomedical credentials as conferring expertise.

“…Research in the field of health communication has indicated how the perceived credibility of an information source can influence the interpretation of public health messages (Haase et al 2015, p. 920;Hample and Hample 2014). Belanger and Szmania (2018) have explored the role of source credibility in the sphere of counter-extremism.…”

This article examines the role of source credibility in the sphere of wildlife conservation campaigns. Specifically, it explores how particular messengers can motivate hunters, ranchers, and wildlife managers in California, Utah, and Arizona to voluntarily adopt non-lead ammunition. I analyze two partner websites, each designed to provide the hunting community with accurate information about non-lead ammunition. I then identify key principles regarding source credibility that arose from semi-structured interviews with four individuals closely involved in North American vulture and raptor conservation: representatives of the Ventana Wildlife Society, the Institute for Wildlife Studies, The Peregrine Fund, and Pinnacles National Park. The conclusion identifies lessons about the role of source credibility in wildlife conservation campaigns and situates the findings in the context of existing research on environmental communication and education.

“…42 Scientific research on communication shows that the quality of the evidence not only influences the audience's attitudes towards a health treatment but also increases credibility. 43 Messages based on scientific approach may have a greater influence on people's attitude toward vaccinations in comparison to affective associations or simple allegations used by deniers. Consequently, underlining scientific messages, based on knowledge and facts, may help improve people's trust on immunization.…”

A safe vaccine against measles has been available and globally recommended since 1974. The World Health Organization established measles elimination as a goal for 2020 but, unfortunately, this objective has not been achieved yet and outbreaks still occur. Herd immunity, ie, a population immunity higher than 95%, is required to stop the measles virus transmission. Communication plays a crucial role in immunization strategy to obtain high coverage levels, as it helps to fight barriers against vaccination. Delay and refusal of measles vaccination have become widespread due to misinformation, fake news and barriers to effective communication. This phenomenon has been defined as "vaccine hesitancy" and is considered as one of the top ten risks for global health. The alleged association between measles vaccination and autism has caused a sharp decline in vaccination rates. In this current situation, mass communication integrated into public health policies is fundamental to sway people's positive attitudes toward vaccination. Digital communication strategies based on social media and other internet platforms may represent useful tools to promote immunization and discourage skepticism and complement information provided by health-care professionals who have been considered as the most credible source on risk/benefits on vaccines for families. Digital communication strategies that may help supporting the measles elimination strategy include monitoring information needs online, integrating digital communication into immunization programs, involving a multidisciplinary group in communication, developing content that balances facts with positive messaging, using multiple communication channels. Further research activities should be promoted in the field of effective communication for immunization.
