ROME: Nearly one in four people may not get COVID-19 vaccines until at least 2022 because rich countries with less than 15% of the global population have reserved 51% of the doses of the most promising vaccines, researchers said on Tuesday.

Low- and middle-income countries - home to more than 85% of the world's population - would have to share the remainder, said researchers from the Johns Hopkins Bloomberg School of Public Health in the United States.
