The 5As: A practical taxonomy for the determinants of vaccine uptake

Abstract

To develop a practical taxonomy to organise the myriad possible root causes of a gap in vaccination coverage rates, we performed a narrative review of the literature and tested whether all non-socio-demographic determinants of coverage could be organised into 4 dimensions: Access, Affordability, Awareness and Acceptance. Forty-three studies were reviewed, from which we identified 23 primary determinants of vaccination uptake. We identified a fifth domain, Activation, which captured interventions such as SMS reminders which effectively nudge people towards getting vaccinated.

My research focuses on understanding how people handle risk and uncertainty. How they perceive and communicate risks, how they make decisions in the face of uncertainty.
