The social nature of today’s Internet is creating new public health and policy challenges. For example, the US in 2014 experienced the largest measles outbreak in nearly a generation, which led to the passing of the nation's most conservative vaccine legislation, eliminating the personal belief exemption in California. Research has identified online misinformation about vaccines as one of the risk factors for this outbreak. Through three big data case analyses on water fluoridation, the Ebola epidemic, and childhood vaccinations, we analyze the influence of scientific evidence and the influence of “social proof,” a form of imitation where individuals ascribe to the behavior of others in order to resolve uncertainty. Our work aims to answer the question, how can we employ network science to develop social communication strategies for public health that build on the strengths and opportunities provided by today's Internet? In other words, instead of asking "How can we share our message with our target audience?" should we be asking "How can our target audience share our message?"
