The city state has already dropped most restrictions for inoculated travellers, and people can now arrive at Changi airport without having to quarantine or test on arrival. Visitors still have to do a test before entering the country.
Most residents in Java have Covid-antibodies
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 per cent of people had Covid-antibodies, a 6 percentage point increase from a December survey.
Pandu Riono, an epidemiologist at the University of Indonesia, which conducted the survey with the health ministry, on Monday told Reuters the antibody levels in the latest survey were higher due to a wider booster shot roll-out, as recipients had stronger protection.
