Vaccine Hesitancy: Where Are We Now?

Abstract

Vaccine hesitancy is the delay in acceptance or outright refusal of immunizations, which has evolved into a growing public health threat. In this article, we explore recent trends in vaccine hesitancy in the setting of the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) pandemic, vaccine-specific variations, social media influence, and sociodemographic factors. During the coronavirus disease 2019 pandemic, the antivaccine movement gained increasing support and generated widespread conspiracy theories and mistrust. This highlighted the importance of enhancing communication between the health care field and general public. While the impact of antivaccine social media is widespread, physicians have also begun to use technology to spread factual information and increase vaccination uptake. There is a growing body of evidence regarding sociodemographic data, including the pervasive impact of medical racism on vaccine hesitancy, with additional studies on age, education, income, and more. Providers must serve as communicators and focus on presumptive language, strong recommendations, and tailored conversations with families who are hesitant about vaccines.
