Beginning today, people in South Korea can make reservations and get inoculated with so-called "leftover vaccines" on the very same day.
The leftover vaccines are ones that had been booked by someone else, who then didn't show up.
Reservations can be made through the Naver and Kakao mobile phone applications.
The move comes as part of government efforts to ramp up the speed of vaccinations.
As of this morning, some 2 million people have been fully vaccinated in the country.
Meanwhile, South Korea reported 629 new COVID-19 cases on Thursday, 620 of which were local and 9 from overseas.
Three more people have died from the virus, raising the death toll to 1,943.
