“…The majority of the videos (65.0%) had a positive tone toward the vaccine's use, which contrasts with the results of Yiannakoulias et al [11], who evaluated 141 videos in English about the vaccine and observed that only 16.3% were in favor of it. This disparity according to language coincides with studies on other vaccines, such as those for human papillomavirus, in which a mostly positive tone was detected in more than three-quarters of the videos in Spanish [24], while in English, positions against the vaccine's use were the most frequent (51.7%) [15].…”

Our objective was to analyze the information in Spanish on YouTube about the influenza vaccine. In August 2020, a search was conducted on YouTube using the terms “Vacuna gripe”, “Vacuna influenza”, and “Vacuna gripa”. Associations between the type of authorship, country of publication, and other variables (such as tone, hoaxes, and vaccination recommendations) were studied via univariate analysis. A total of 100 videos were evaluated; 57.0% were created in Mexico (24.0%), Argentina (17.0%), and Spain (16.0%), and 74.0% were produced by mass media or health professionals. Positive messages were detected in 65.0%. The main topics were the benefits of the vaccine (59.0%) and adverse effects (39.0%). Hoaxes were detected in 19 videos. User-generated content, compared to that of health professionals, showed a higher probability of hoaxes (odds ratio (OR) = 15.56), a lower positive tone (OR = 0.04), and less evidence of recommendations to vaccinate pregnant individuals (OR = 0.09) and people aged 60/65 or older. Videos published in Spain, in comparison with those from Hispanic America, presented significant differences in the positive tone of their messages (OR = 0.19) and in the evidence of the benefits of vaccination (OR = 0.32). A higher probability of hoaxes was detected in videos from Spain and the USA. Information in Spanish about the influenza vaccine on YouTube is usually not very complete. Spanish health professionals are urged to produce pro-vaccination videos that counteract hoaxes, and users in Hispanic America should be advised to consult videos produced in Hispanic American countries by health professionals to obtain reliable information.

“…Overall, 32% (22/69) of the studies focused on vaccines or vaccination decision-making-related topics. Additionally, 14% (10/69) of the selected articles focused on social media discussion regarding the potential side effects of vaccination [23,36,48,53,55,60,65,77,87,88], 12% (8/69) were centered on the debate around the HPV vaccine [42,[49][50][51]67,68,79,94], and 3% (2/69) were centered on the antivaccine movement [39,43]. According to social media platforms, 9% (6/69) of the studies were focused on the debate and narratives about vaccines in general on Twitter, and 6% (4/69) specifically analyzed the HPV debate on this platform.…”

Prevalence of Health Misinformation on Social Media: Systematic Review

2021

View full text Add to dashboard Cite

Background Although at present there is broad agreement among researchers, health professionals, and policy makers on the need to control and combat health misinformation, the magnitude of this problem is still unknown. Consequently, it is fundamental to discover both the most prevalent health topics and the social media platforms from which these topics are initially framed and subsequently disseminated. Objective This systematic review aimed to identify the main health misinformation topics and their prevalence on different social media platforms, focusing on methodological quality and the diverse solutions that are being implemented to address this public health concern. Methods We searched PubMed, MEDLINE, Scopus, and Web of Science for articles published in English before March 2019, with a focus on the study of health misinformation in social media. We defined health misinformation as a health-related claim that is based on anecdotal evidence, false, or misleading owing to the lack of existing scientific knowledge. We included (1) articles that focused on health misinformation in social media, including those in which the authors discussed the consequences or purposes of health misinformation and (2) studies that described empirical findings regarding the measurement of health misinformation on these platforms. Results A total of 69 studies were identified as eligible, and they covered a wide range of health topics and social media platforms. The topics were articulated around the following six principal categories: vaccines (32%), drugs or smoking (22%), noncommunicable diseases (19%), pandemics (10%), eating disorders (9%), and medical treatments (7%). Studies were mainly based on the following five methodological approaches: social network analysis (28%), evaluating content (26%), evaluating quality (24%), content/text analysis (16%), and sentiment analysis (6%). Health misinformation was most prevalent in studies related to smoking products and drugs such as opioids and marijuana. Posts with misinformation reached 87% in some studies. Health misinformation about vaccines was also very common (43%), with the human papilloma virus vaccine being the most affected. Health misinformation related to diets or pro–eating disorder arguments were moderate in comparison to the aforementioned topics (36%). Studies focused on diseases (ie, noncommunicable diseases and pandemics) also reported moderate misinformation rates (40%), especially in the case of cancer. Finally, the lowest levels of health misinformation were related to medical treatments (30%). Conclusions The prevalence of health misinformation was the highest on Twitter and on issues related to smoking products and drugs. However, misinformation on major public health issues, such as vaccines and diseases, was also high. Our study offers a comprehensive characterization of the dominant health misinformation topics and a comprehensive description of their prevalence on different social media platforms, which can guide future studies and help in the development of evidence-based digital policy action plans.

“…11,19 These findings are reflected by other studies, which revealed that YouTube videos disapproving of immunization were more viewed, liked, or shared. 20,21 In a study conducted in the UK, parents who believed in anti-vaccine conspiracy theories were less likely to vaccinate a fictitious child, suggesting that initiatives to increase vaccine uptake should also address the impact of conspiracy theories. 22 Understanding the origin of conspiracy theories and developing initiatives to limit the dissemination of harmful healthrelated information is much more complex and multi-layered than it may appear.…”

The golden age of anti-vaccine conspiracies

To the dismay, disbelief, and amusement of many, a few months back, in a widely shared social media post, a person planning to travel with their toddler mentioned having heard that certain airline companies vaccinate people through the air conditioning system. The person was reaching out to seek additional information on which airlines were doing this. Leaving aside the fact that no airborne human vaccines-which would make life so much easier for children and vaccination programs alike-are currently available, this reminded me, yet again, that conspiracy theories on social media are alive and thriving, rejoicing their golden age. One of the most successful interventions in the history of medicine, vaccination led to the global eradication of smallpox, the nearly global eradication of polio, and the drastic decrease in the morbidity and mortality associated with other infectious diseases. As a result of this success, many parents are unaware of the threats and burden that infectious diseases posed for previous generations. 1-3 To a great extent, this explains that vaccines have become victims of their own success. 2 Conspiratorial beliefs have become endemic among anti-vaccination groups. 4 Opposition to vaccination is not new-it dates back to the Victorian age and since the 18 th century, fear and controversy accompanied the introduction of every new vaccine. 5,6 This has been compounded, in recent years, by a decreased trust in the institutions that manufacture or
