YouTube as a source of public health information regarding COVID-19 vaccination: an assessment of reliability and quality of video content
ABSTRACT
Background:
Recent emergency authorisation and rollout of COVID-19 vaccines by regulatory bodies has generated global attention. As the most popular video-sharing platform globally, YouTube is a potent medium for dissemination of key public health information. Understanding the nature of available content regarding COVID-19 vaccination on this widely used platform is of substantial public health interest.
Objective:
To evaluate the reliability and quality of information of YouTube videos regarding COVID-19 vaccination.
Methods:
For this cross-sectional study, the phrases ‘coronavirus vaccine’ and ‘COVID-19 vaccine’ were searched on the UK version of YouTube on December 10, 2020. The 200 most-viewed videos of each search were extracted and screened for relevance and English language. Video content and characteristics were extracted and independently rated against Health on the Net Foundation Code of Conduct (HONCode) and DISCERN quality criteria for consumer health information by two authors.
Results:
Forty-eight videos, with a combined total view count of 30,100,561, were included in the analysis. Topics addressed comprised: vaccine science (58%), vaccine trials (58%), side effects (48%), efficacy (35%) and manufacturing (17%). Twenty-one percent of videos encouraged continued public health measures. Only 4.2% of videos made non-factual claims. Ninety-eight percent of video content was scored to have low (60%) or medium (38%) adherence to HONCode principles. Educational channels produced by both medical and non-medical professionals achieved significantly higher DISCERN scores than other categories. The highest DISCERN scores were achieved by educational videos produced by medical professionals (64.3 (58.5-66.3)) and the lowest scores by independent users (18 (18-20)).
Conclusions:
Overall quality and reliability of information on YouTube regarding COVID-19 vaccines remains poor. Videos produced by educational channels, especially by medical professionals, were higher in quality and reliability than those produced by other sources, including health-related organisations. Collaboration between health-related organisations and established medical and educational YouTube content producers provide an opportunity for dissemination of high-quality information regarding COVID-19 vaccination. Such collaboration holds potential as a rapidly implementable public health intervention aiming to engage a wide audience and increase public awareness and knowledge.
