In a June 2021 survey of over 23,000 individuals across 23 countries, the researchers found that more than three-quarters (75.2%) of respondents reported vaccine acceptance, up from 71.5% one year earlier.

The study, which was published Monday in Nature Communications, was carried out within the context of a year of substantial but very unequal global COVID-19 vaccine availability and acceptance, which necessitated new assessments of the drivers of vaccine hesitancy and the characteristics of people not vaccinated.
