We turn to some local news,
Eleven weeks after the first doses started, South Korea will start giving certain people their second dose of AstraZeneca's COVID-19 vaccine from Friday.
Nursing home residents and staff under 65 years old are among the first in line.
Those under 30, who received their first dose before the government's age restriction was implemented, can decide themselves if they want the second shot.
Around 926-thousand people are eligible for second doses between now and June.
Health authorities are urging active participation, noting that data from abroad shows side effects are less frequent for the second dose.
