With about 45% of the U.S. population fully vaccinated against COVID-19 and cases declining in a majority of states, Americans across the country gathered with family and friends at parades, picnics and barbecues over the weekend to mark the Juneteenth federal holiday.

But across the globe, it's not such a rosy picture. Nearly 85% of all COVID-19 vaccine doses globally have been administered in high- and upper-middle-income countries, according to the World Health Organization.

Less than 1% of Africa's population is fully vaccinated, and the continent is seeing a surge of cases, according to the WHO. Twenty-two African countries saw cases rise by over 20% last week, and several nations reported their highest number of new weekly cases since the pandemic began.
