Emergence of Vaccine-Preventable Diseases: The Perfect Storm of Hesitancy, Refusal, a Pandemic, and War.

Abstract

The landscape of pediatric vaccination has changed dramatically due to changing attitudes toward immunizations and recent world events. The rise of vaccine hesitancy and refusal related to the concurrent rise of social media and anti-vaccination messages with misinformation campaigns have led to populations of children being unimmunized or under-immunized. These populations have been left vulnerable to the rapid spread of vaccine-preventable infection. Additionally, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the clinical syndrome known as coronavirus disease 2019 (COVID-19) resulted in the emergence of a worldwide pandemic. Control measures to mitigate the spread of COVID-19 resulted in numerous reports of children missing routine vaccines along with the stopping of many public health immunization programs. Finally, armed conflicts and war have led to large family migrations from their homelands to various countries and regions leading to increased risk for missed maternal and child immunization as well as difficulty in keeping vaccination records.
