We do not know when the quarantine will end. If you arrive to Vietnam before the quarantine ends, you will have a choice: either to go back without leaving the airport, or to stay in the barracks for the 14-day quarantine.
Those who are already in Vietnam can safely stay in the country. You can also extend your stay in Vietnam. We extend both the 15-day stamp and the visas. You can read about visas by clicking on the "more information" button.
