I am the head of an international school in Spain, we are encountering parents who do not want to comply with our vaccination requirement for admissions. This article is incredibly timely and illustrates starkly the difficulty we face deeply rooted and strongly held beliefs based on the stories that are passed along until they have the feel of truth because they seem to always have been there. We find families making up histories to fit the truths they hold to. It is fascinating but deeply troubling for our health and safety. We live in an age of denial (see the excellent Op-Ed piece in the NYTimes Welcome to the Age of Denial by @AdamFrank4, an astrophysicist at the University of Rochester). It is a great irony that rise of denial has coincided with the the greatest availability of knowledge.
