Understanding the Reasons Behind Reversals in COVID-19 Vaccination Hesitancy & Willingness
August 9, 2022 Keio University School of Medicine
A research team at Keio University has conducted two large-scale national online surveys of Japanese adults aged 20 and older regarding COVID-19 vaccination willingness. The team was led by Project Associate Professor Shuhei Nomura and researcher Cyrus Ghaznavi of the Department of Health Care Policy and Management at the Keio University School of Medicine.
The first survey was conducted in February 2021, just before COVID-19 vaccinations became available to the general population in Japan; the second survey was conducted one year later in February 2022. The team analyzed data from approximately 20,000 respondents using multidimensional statistical methods and summarized the characteristics of those who had changed their minds regarding vaccination willingness during the past year.
The results of this study were published as two separate research papers in the British medical journal The Lancet Regional Health - Western Pacific on July 21, 2022 (BST).
