Análisis del contenido publicado en YouTube, Facebook e internet sobre vacunas y anti vacunas

Résumé

This article analyses the information about vaccines and anti-vaccines that is shared on blogs, Facebook, and YouTube by monitoring publications from 2015 to the present. The origin of the source of the information, the published content, and the generated engagement have been taken into account. The results, obtained from the study of 48 YouTube videos, 207 posts from 5 different blogs and 7 Facebook groups, confirm that: a) the anti-vaccine or pro-vaccine information does not usually come from official sources; b) the shared content orbits around certain recurring issues and it is usually linked to specific events (for example, a measles outbreak or a particular complaint for side effects of a vaccine); c) the shared content, generally, is not based on scientific evidence, and; d) the interactions generated by users vary greatly depending on whether the information is transmitted by YouTube, a blog, or Facebook. Generally, both blogs and YouTube generate more followers, interactions, and comments than Facebook groups
