COVID-19 vaccine acceptance and hesitancy in low- and middle-income countries
A safe and effective vaccine is a critical tool to control the COVID-19 pandemic. As of 25 June 2021, 23 vaccines had advanced to Stage 3 clinical trials1 and more than a dozen had been approved in multiple countries2. The BNT162b vaccine from Pfizer–BioNTech, for example, has been approved in about 90 countries, while the ChAdOx1 nCoV-19 vaccine from Oxford–AstraZeneca has the most country authorizations at 1152. At present, however, global vaccine distribution remains highly unequal, with much of the current supply directed toward high-income countries3.
