Some things just do not want to die. In public health, anti-vaccination movements keep sizzling debates, just as they did in the XIX century. At the same time,  the “deficit model” of science communication – the myth that the “public” is just ignorant and that it would support science, if spoon-fed information from the ivory tower – still haunts the relationship between health, science and the community, despite having been repeatedly debunked. The two zombies are more related than one could believe. Vaccine hesitancy and anti-vaccination movements grow in the cracks between trust and knowledge, and these are the fault lines that communication should heal – or rip apart, if it fails.
