Fully vaccinated individuals coming into South Korea will now have to take a PCR test within one day of arrival, starting Monday, to avoid mandatory two-week quarantine.
The rule adds a further PCR test to current measures, that requires tests to be taken both prior to departure and six to seven days after arrival.
In addition, before the changes on Monday, those who left Korea before being considered fully vaccinated, or within two weeks of their second or final dose, faced a two-week quarantine upon return.
Now even if a person departs within two weeks of their final dose, as long as two weeks have passed when coming back to South Korea, they will be exempt from quarantine.
The changes have been made to make things more convenient for fully vaccinated travelers, while still checking thoroughly for any possible breakthrough cases.
