Some people who were vaccinated at workplaces and universities during vaccination drives that started last summer have still not submitted their vaccination cards to their workplaces or schools.
If the cards are not submitted, municipal governments cannot obtain data on vaccinations, which could delay booster shots.
As infections from the omicron variant spread, the government is calling for a faster timeline for administering boosters, and local governments, companies and universities are urging people to submit their vaccination cards as soon as possible.
