Starting Tuesday teenagers aged 16 or 17 will be able to book vaccine appointments with their parents' consent.
Like previous methods reserving a slot will be done online starting 8 PM.
And, beginning October 18th those with reservations will begin getting the mRNA vaccine from Pfizer with a THREE-WEEK interval between the first and second dose.
Amid concerns over vaccine hesitancy, health authorities have urged parents and children to get the shot as soon as possible, saying the benefits far outweigh the risks.
" Especially, teenagers with underlying conditions have larger risks after catching COVID-19, so the government urges them to get vaccinated."
For children between 12 and 15 years old their booking window starts on October 18th and their vaccinations will kick off in November, and they also need parental consent.
Bookings for booster shots also start on Tuesday.
Over-60s and most medical workers will be eligible to reserve this third shot of the vaccine.
Meanwhile, health authorities have come up with new ways for fully vaccinated people from overseas to show their proof of vaccination.
A lot of people who have gotten their COVID-19 vaccines outside of Korea, have found it difficult to prove their inoculation status when visiting coffee shops and restaurants.
Starting October 7th, those who come to Korea with a quarantine exemption document can register their information online, using apps like 'Coov' at local health centers.
This will help travelers inoculated abroad and U.S. soldiers stationed in Korea prove their vaccination status.
However, it only applies to vaccines that are approved by the WHO.
On Tuesday 1-thousand 5-hundred-75 new COVID-19 infections were reported.
Of them, all but 18 were locally transmitted and the total caseload is now over 321-thousand.
The daily tally was slightly less than the previous day because of fewer tests conducted over the three-day weekend.
Authorities are concerned about a holiday surge as more people traveled around the country during the three-day holiday.
