South Korea's government launched a new online system on Thursday to help prevent coronavirus vaccine doses from being wasted.
Medical institutions can input the number of leftover doses into the system. People can check the number of doses available at different locations and times through the website and map apps.
They can register with medical institutions and be notified if there are any leftovers.
A hospital director said, "People don't need to call. They can reserve a vaccination by simply tapping OK on devices such as smartphones. Large volumes of vaccines won't have to be discarded, and the rollout can proceed smoothly."
People aged 30 and over who have never received a coronavirus vaccine and who have no other bookings are eligible for the program.
