South Korea said on Thursday it will issue so-called COVID-19 vaccine passports to immunized citizens. 

At a government meeting, Prime Minister Chung Sye-kyun said a mobile app, which will allow international travelers to show digital proof of vaccination, will be officially launched in April. 

"The introduction of a vaccine passport or 'Green Pass' will only allow those who have been vaccinated to experience the recovery to their daily lives," Chung said.
