On Twitter, Anti-Vaccination Sentiments Spread More Easily than Pro-Vaccination Sentiments

Caption: On Twitter, a research team tracked the pro-vaccine and anti-vaccine messages about a new vaccine for combating a virus strain responsible for swine flu, and then observed how Twitter users expressed their own sentiments about the vaccine. The results may help health officials improve strategies for vaccination-awareness efforts. This image is a network diagram showing connected Twitter users expressing negative (red) and positive (green) sentiments about vaccination.
