But there has been a surge in serious cases among people in their 60s or older, including those whose immunities have waned after getting inoculated early in the vaccine rollout that began in February. More than 81% of the population of over 51 million has been fully vaccinated, but only 17% of people have received booster shots. She said that would push the number of serious cases to between 1,600 and 1,900, possibly beyond what hospitals could handle without sacrificing their non-COVID-19 care. Health Minister Kwon Deok-cheol said the four-person gatherings limit will only be applied to fully vaccinated adults. Those who aren’t fully vaccinated will be required to eat alone at restaurants, Kwon said.
