On Thursday it kicked off vaccination for people aged 18 to 49, as it aims to give at least one dose to 70 per cent of the population and fully vaccinate 50 per cent by September.
South Korea has been struggling to boost its immunisation drive that began in February amid supply shortages and shipment delays, with about 52.7 per cent of its 52 million people having received at least one dose, while just 26 per cent are fully vaccinated.
Of the eligible 15 million in the 18-49 age bracket, just below 70 per cent had signed up for vaccination, the Korea Disease Control and Prevention Agency (KDCA) said.
South Korea reported 1,882 new coronavirus cases, bringing the total to 243,317. A total of 2,257 people have died so far, the KDCA data showed.
