"What is the problem with vaccines?" A typology of religious vaccine skepticism.

Research has identified religion as one of numerous factors that may contribute to delay or refusal of vaccination. The influence of religion on vaccine decisions may be accidental, or it may involve explicit religious objections. By presenting a typology of religious vaccine skepticism, this article seeks to give a comprehensive overview of the essence of these objections and to clarify differences and similarities between them. This knowledge is useful for policy-makers and others who wish to better understand the influence of religion on vaccine decision-making. The typology consists of five main types: (1) a worldview clash type, in which vaccines do not make sense as a health intervention; (2) a divine will type, which represents a form of passive fatalism; (3) an immorality type, which considers some vaccines unethical because of their production or effect; (4) an impurity type, pointing to ingredients that will defile the body; and (5) a conspiracy type, in which a vaccine plot is targeting a religious group.
