Almost all residents of Indonesia's most populous island of Java have antibodies against COVID-19, owing to a combination of prior infection and vaccination against the virus, a government-commissioned survey showed.
The March study of 2,100 people, conducted on Java, home to 150 million people, and Bali, Indonesia's top tourism destination, revealed 99.2% of people had COVID antibodies, a 6 percentage point increase from a December survey.
