What is the current vaccine proof requirement for entering Thailand as of July 2022?

As of July 1, 2022, travelers entering Thailand are generally required to show proof of vaccination, with accepted forms including digital and hard copies of vaccination certificates. While some travelers have successfully used the European vaccination cert on their phones, it is advisable to also carry printed copies for entry. Vaccinated individuals must show a certificate for at least two doses, and unvaccinated travelers may need to present a recent PCR test or a professional antigen test. Immigration appears to prefer physical documents that can be stamped.
