Japan has given first doses of a COVID-19 vaccine to 63.6% of its population, surpassing the U.S. in the proportion of those who have had at least one shot of the vaccine despite starting months behind.

The nation’s progress now puts the U.S. last among Group of Seven nations when it comes to the proportion of the population with at least one dose, after vaccine hesitancy squandered the country’s head start. About 63.1% of the U.S. has had at least their first shot, and 53.8% are fully vaccinated.

Japan has administered a total of 145.8 million shots, and over 51% of its population is fully vaccinated, according to government figures released Tuesday.
