The effect of trust and proximity on vaccine propensity

Abstract

The main goal of this paper is to study the effects of (1) trust in government medical experts and (2) proximity to a recent disease outbreak on vaccine propensity. More specifically, we explore how these variables affect attitudes with regards to measles. Using original survey data, collected in January/February 2017, we obtain three main empirical findings. First , contrary to our expectations, an individual’s proximity to a recent measles outbreak has no independent effect on vaccination attitudes. Second , corroborating previous studies in the field, we find that trust in institutions such as the CDC has a positive effect on our dependent variable. Third , there is a significant interactive relationship between proximity and trust in governmental medical experts. While distance from a previous measles outbreak has no effect on vaccination attitudes for respondents with medium or high levels of trust, the variable exerts a negative effect for subjects with little confidence in government medical experts. In other words: low-trust individuals who live farther away from a recent measles outbreak harbor less favorable views about vaccination for this particular disease than low-trust respondents who live close to an affected area. This implies that citizens who are skeptical of the CDC and similar institutions base their vaccination decision-making to some degree on whether or not a given disease occurs in close vicinity to their community.

Risk of disease and willingness to vaccinate in the United States: A population-based survey

“…What is not well understood, however, is how change in perceived risk translates into change in vaccine hesitancy. In other words, we do not yet have a sufficiently rich understanding of "vaccine propensity," a concept introduced by Justwan and colleagues [12] that we further advance here.…”

“…[59][60][61] They have also characterized important relationships between vaccine confidence and contextual factors, such as geographical proximity to vaccine-preventable outbreaks and political trends. 62,63 Findings have also reinforced early impressions that while social media and other Web 2.0 tools are promising to disseminate accurate information on vaccines, they have also become a tool that has been leveraged more effectively by anti-vaccinationists than public health. 64,65 A recent analysis of Facebook responses to a South African HPV vaccination campaign found that while the majority of reactions (97%) on the page were favorable towards the vaccine, 33% of the comments were categorized as vaccine hesitant, "suggesting that people with negative reactions though few in numbers, were more likely to be vocal deniers".…”

Rapid realist review of the role of community pharmacy in the public health response to COVID-19

“…In addition, pharmacy users seek out community pharmacy services due to their accessibility and convenience, and without a physical space to engage regularly with pharmacy users, trust building between pharmacists and users is compromised. 64 …”
