Tyler Dawson and Sharon Kirkey look at what we know about them, why it matters and how they got there in the first place. You can essentially break anti-vaxxers into two groups, says Tim Caulfield, the Canada Research Chair in health law and policy at the University of Alberta. Those who are already faintly skeptical are more susceptible to the fear-mongering and rhetoric of hard-line anti-vaxxers, Caulfield said. According to the poll, 65 per cent cite health reasons for not vaccinating, and 19 per cent give religious reasons. Caulfield said anti-vaxxers trend slightly male — and some research from the United States backs that up.
