In a collective effort bringing together 15 studies, researchers from over 30 institutions surveyed over 20,000 individuals between June 2020 and January 2021 on questions regarding respondents’ vaccine acceptance and hesitancy and their most trusted sources for vaccination advice. During some surveys, results from COVID-19 vaccine clinical trials had yet to be announced, and during later surveys, governments had started approving vaccines for use. The fast-moving nature of COVID-19 information may change people’s perceptions about vaccines by the time they are widely available in low- and middle-income countries (LMICs). Over the past six months, the body of evidence demonstrating the safety and efficacy of available COVID-19 vaccines, which have been given to millions of people, has become clearer. At the same time, severe, but rare, side effects may have undermined public confidence.
