A Conceptual Framework for the Development of Chatbots Addressing COVID-19 Vaccine Hesitancy

Abstract

Aim of this letter is to review Chatbots that answer questions of vaccine-hesitant people, their utility, and their limitations in addressing psycho-social determinants of COVID-19 vaccine hesitancy. The authors propose a conceptual framework that could guide the development of artificial intelligence-based Chatbots and summarise the salient features of the four Chatbots discussed in the literature today, developed to address COVID-19 vaccine hesitancy.
