In the United Kingdom's National Health Service, 50 percent of health care workers do not get flu vaccines. Obviously they are not anti-vaccine, they work in health care, so what explains their behavior? It isn't as simple as science denial.In the United States, vaccine denial is easier to predict: Go to a political map of California or Oregon and find the counties that voted overwhelmingly for President Obama and you are going to find an anti-vaccine hotbed. Still, though that tells us where it does not tell us why and we need to know why in order to know how to solve the problem. It isn't as simplistic as 'Democrats are anti-science', though it is reasonable that it's been framed that way.
