In the early hours of Wednesday, at about 1:30 AM, South Korea took delivery of 436-thousand doses of the Pfizer vaccine.
The country has now received more than 2.4 million doses of the 66 million Pfizer has agreed to supply.
By next month, it'll get another 4.5 million.
The Pfizer vaccine is currently being administered to seniors 75 and older and to nursing home workers, and next month, the government plans to inoculate 640-thousand essential workers and military personnel younger than 30.
Also, starting today, South Korea is ending its requirement that people returning to the country from overseas self-isolate for two weeks if they've been fully vaccinated here in Korea.
That requirement is ended also for vaccinated people who've come in contact with someone who's infected.
They will, however, have to have been vaccinated for two weeks already, test negative for the virus and show no symptoms.
It will not apply to people arriving from nine countries battling variants of the virus, including South Africa and Brazil, and it won't yet apply to people who got their vaccine outside of Korea.
Meanwhile, South Korea reported 676 new COVID-19 cases on Wednesday the first time in three days that cases have been above 600.
Out of 651 locally transmitted cases, more than 35-percent came from outside the capital region raising conerns that the virus is spreading all across the country.
There were seven more deaths on Wednesday bringing the death toll to 1,847.
