In Japan, just over 21 percent of all elderly people have received at least one shot of a coronavirus vaccine.
Vaccinations for people aged 65 or older began in the country in April. Medical professionals started receiving the inoculations in February.
Data released by the government on Monday shows 7,747,259, or 21.8 percent of the nation's elderly people, have received at least one shot. The data shows that 852,845, or 2.4 percent, have gotten their second inoculation.
By prefecture, Wakayama had the highest elderly vaccination rate, with 35.8 percent having received at least one jab. Okayama and Saga prefectures came in second with rates of 34.5 percent each.
Tokyo's vaccination rate was 24.8 percent, while Osaka Prefecture's rate was 19.2 percent. Aichi Prefecture's rate was 26.1 percent.
The data is based on vaccination numbers that the prefectures reported to the central government by Sunday.
