In the other survey, which targeted a total of 18,048 blood donors across all of Japan’s prefectures, the antibody rate exceeded 60 percent in a total of 38 prefectures, including the northernmost prefectures of Hokkaido and Tokyo. The highest rate was seen in the southernmost prefecture of Okinawa, at 77.6 percent, and the lowest in Akita Prefecture, at 50 percent. (UNI)
