Enough vaccines have now been administered to fully vaccinate about 5% of the global population — but the distribution has been lopsided. Most vaccines are going to the wealthiest countries.

As of Thursday, 40% of the COVID-19 vaccines administered globally have gone to people in 27 wealthy nations that represent 11% of the global population. Countries making up the least-wealthy 11% have gotten just 1.6% of COVID-19 vaccines administered so far, according to an analysis of data collected by the Bloomberg Vaccine Tracker.

In other words, countries with the highest incomes are vaccinating 25 times faster than those with the lowest.
