HERNANDEZ-GARCIA, I.  y  TARANCON-CEBRIAN, I.. Characteristics of YouTube videos in Spanish about the influenza vaccine. Anales Sis San Navarra [online]. 2020, vol.43, n.1, pp.35-41.  Epub 17-Ago-2020. ISSN 1137-6627.


To analyze the characteristics of YouTube videos in Spanish about the influenza vaccine.


In April 2019, a search was conducted on YouTube with the term vacuna gripe. We studied the association between the type of author, and country of publication, and the rest of the variables (tone of the message, type of publication, and vaccination recommendations according to the Spanish Ministry of Health, among others) with univariate analysis and a multiple logistic regression model.


In total, 208 videos were assessed; 51.0% had been published from Spain and Mexico, and 79.8% of the videos supported the use of influenza vaccines. The main topics discussed in the videos were whether the vaccine should be considered the most effective method to prevent influenza (64.4%) and recommendations concerning the vaccination of people over 65 years old (43.3%). The variables type of authorship (healthcare professionals) and country of publication (Spain) were associated with a positive attitude towards vaccination (OR: 2.91; 95%CI: 1.12-7.53 and OR: 0.31; 95%CI: 0.15-0.65, respectively).


The existing information on YouTube about the influenza vaccine is not generally very complete, and it varies depending on the authorship of the videos and the country of publication. It would be advisable for healthcare professionals to publish videos promoting vaccination based on the guidelines from the Spanish Ministry of Health, and it is necessary to promote those videos for Spanish users who search for reliable information about this vaccine on YouTube.
