the good, the bad and the ugly: a portrait of health social media trends and anti-vaccination
DESCRIPTION
The Good, the Bad and the Ugly: a portrait of health social media trends and anti-vaccination. This presentation was made for the Norwegian Knowledge Centre for the Health Service. Global Health Unit Open Seminar – 6th August 2013 In this presentation, we will introduce how social media is being used in transforming communication with patients. We will use study cases, such as the ‘zombi invasion’ organised by the CDC and online puzzles for biomedical research, to provide an overview of current trends. In addition, we will present research conducted at Norut (Northern Research Institute) about the challenges of finding trustworthy health social media. Our focus will be directed towards harmful online communities promoting anorexia as a lifestyle or anti-vaccination online groups.TRANSCRIPT

Global Concern

“With ever increasing access to Internet-based information, an unsubstantiated rumour about vaccines can rapidly circle the globe and undermine immunization services, sparking outbreaks of disease and untold deaths.”

Anti-vaccination movement 2.0
Studies show:– With questions regards about vaccination the most trusted
source are physicians. However, 70% will check Internet and only 30% physicians. (USA)
– In many cases misleading information in social media has been found to be more popular (e.g. HPV in YouTube, Forums about measles vaccination).
– In some cases anti-vaccination webs are ranked higher than leading information

Map of Anti-vaccination 2.0
“Although 11 (28%) of the 39 reports about HPV in India obtained during the study period (May 1, 2011, to April 30, 2012) were positive or neutral about HPV vaccines, most, 28 (72%), were negative”

• Lack of knowledge on health social media in developing countries.
• Anti-vaccination is being catalyzed by social media, but it is not fully understood.– Quantification of the impact of online anti-vaccination propaganda.
– Why anti-vaccination is successful in social media (vs. health authorities).
