has shown that the way physicians pose the topic of vaccines influences how likely the parent is to refuse the vaccine (2013). Opel et al. generalized the two types of approaches physicians use as either the participatory or presumptive style. The participatory approach involved asking parents whether they wanted to vaccinate. Conversely, the presumptive style simply involves stating that the vaccines will be done, and not asking.

Furthermore, when attempted to convince parents who initially resisted, 47% of parents eventually accepted the vaccines. Therefore, when a physician exerted more control over the situation, parents were more likely to vaccinate their
