COVID-19 Vaccine Hesitancy in Japan: Determinants, Reasons, and a Potential Solution

Zoom Meeting

  • Sawako Shirahase TCJS Director
Event Description

Even though the degree and duration of vaccines’ efficacies remain unconfirmed, widespread vaccination, by establishing herd immunity against the new coronavirus disease (COVID-19), is a demanded step to the pandemic end. However, vaccine hesitancy, defined as ‘delay in acceptance or refusal of vaccines despite availability of vaccine services’, can hinder achieving herd immunity. In this study, we investigated determinants and reasons for COVID-19 vaccine hesitancy, utilising a sample of Japanese adults aged between 20 and 74, collected through an online survey in July 2021. Furthermore, we conducted a conjoint experiment to evaluate if relaxing social distancing policies can increase vaccination intentions.
