Singapore and the Republic of Korea have agreed to jointly launch Vaccinated Travel Lanes (VTLs), which will start from Nov 15.
According to a statement by the ministry of transport on Oct 8, under the VTLs, fully vaccinated travellers will be able to travel between Changi Airport and Incheon International Airport, and be subjected to Covid-19 Polymerase Chain Reaction (PCR) tests, in lieu of serving quarantine or stay-home notice.
