In the last 7 days the United States has administered more than 21 million COVID-19 vaccinations, which is equivalent to roughly 6.5% of the entire US population receiving a dose in a single week (data from Our World In Data).
Pump those numbers up
The pace being set in the US is now among the fastest in the world, surpassing even the UK's best week from the last few months. If the US maintains this pace (a big "if") it would mean full vaccination coverage could take just another ~15 weeks, assuming "full coverage" is around 75% of a population having had 2 doses. Despite a slower start, Australia, Canada and the EU are also ramping up their programmes.
Although the US acceleration has been impressive, it's still not enough to top the global cumulative leaderboard.Israel remains at the top of that table, having administered 117 doses per 100 people (i.e. they are on their second round for most people).
P.S. The 4 countries shown in the chart plus the EU accounts for 95%+ of our readership, but if we haven't plotted your country here we recommend you check out the full data set from Our World In Data.
