Researchers at UCLA have built a computation model that enables computers to understand structured narratives within the flow of posts on the internet. The researchers applied this model to examine 2 million posts from two parenting sites. The results found that a large number of parents were not only going online to talk about vaccines, their distrust of institutions requiring them, or the perceived health risks of vaccinations, but seeking out ways to acquire vaccination exemptions for their children. Their findings could have real implications for those working in the public health field to educate parents about vaccinations. You can read more about their finding on the UCLA Newsroom site.
