Global Concern
6th August, 2013
“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.”
State of the World’s Vaccines and ImmunizationWHO, Unicef and the World Bank (2010)

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
