For vaccinated returnees arriving from medium risk regions, who don't have positive test results for anti-bodies, can pay for and undergo anti-bodies tests when they are subjected to the test-and-hold arrangement at the airport.

Returnees also need to test negative for the virus before traveling to designated quarantine hotels by point-to-point vehicles arranged by the government.

The results for the anti-bodies test should be available in two days. If the results came back positive, the quarantine period will then be shortened to only seven days.

Return can ask the quarantine hotels for refund for the remaining seven-night reservation.

During that seven-day quarantine, returnees will have to undergo two Covid tests followed by a seven-day self-monitoring. Returnees must also undergo compulsory testing on the ninth, 12th, 16th and 19th day upon their arrival.
