South Korea's first vaccinations will begin on February 26, with healthcare workers and vulnerable residents, including the elderly, the first in line.
Those remaining in the immediate priority groups for the first dose are set to receive their vaccine dose next.
The groups that should be next in line, according to the province, include Indigenous adults in northern remote and higher risk communities and health-care workers with the highest risk of exposure to COVID-19.
Highest-priority health-care workers - such as paramedics and staff in critical care units, emergency departments and COVID-19 medical units - followed by very high priority health-care workers - such as those in surgical care, obstetrics, assisted living facilities and palliative care settings.
Health care workers in the high priority level, and in keeping with health ministry guidance.
Several European countries have warned that AstraZeneca/Oxford University's shot should only be given to those ages 18 to 64, but the company has said it triggers a good immune response in older people. Those groups will receive the second dose between 21 and 27 days after their first.
He added the government would "not rest" until vaccines were offered to all of the Joint Committee on Vaccination and Immunisation's top nine priority groups by the end of April, and after this all adults.
But the federal government has indicated that Canada expects to ramp up its vaccination effort this spring when the country receives an influx in vaccines next month.
South Korea also reversed its earlier plan on the use of the AstraZeneca vaccine and said it would delay inoculation of the elderly using the shot until more efficacy data becomes available.
Dr. Isaac Bogoch, infectious diseases specialist with Toronto General Hospital and a member of Ontario's COVID-19 vaccine distribution task force, told CBC News Network on Sunday that the key development is that the program is going to expand.
