Public confidence in vaccines varies widely around the world, with low but improving acceptance in some areas of Europe and growing wariness in countries experiencing political instability and religious extremism, according to the largest known vaccine confidence modeling study.The study, published yesterday in The Lancet, analyzed data from 290 nationally representative surveys of 284,381 adults in 149 countries collected from September 2015 to December 2019 on the importance, efficacy, and safety of vaccines.
The data are regularly collected by the Vaccine Confidence Project at the London School of Hygiene & Tropical Medicine, which led the study.The findings could spell trouble as officials roll out COVID-19 vaccines in the coming months
