Starting at 9am on February 1, fully vaccinated travellers from any country can apply for a Thailand Pass QR code to enter with (almost) quarantine-free travel, but there have been a few changes.
1. Those who had previously applied for a Thailand Pass QR code to enter under the Test & Go scheme have been able to enter the country under basically the same conditions.
2. Two RT-PCR tests are now required, new applicants have to pay for both
3. Those who are fully vaccinated against Covid-19, but were recently infected and are still testing positive for the virus can still enter the country under the Test & Go scheme.
