The Influence of Vaccine-Critical Websites on Perception of Vaccination Risks

Last year the university of Erfurt ran a study where www.impfschaden.info was compared with a pro vaccine website of the government. That is what they wrote in the conclusion:

Our analyses reveal that viewing typical vaccine-critical websites for only five to ten

minutes increases the perception of risk regarding vaccinations and decreases the perception

of risk regarding the omission of vaccinations as compared to visiting a control site.

Moreover, acquiring information about vaccinations on a vaccine-critical website

significantly decreased the intentions to vaccinate.
