What are the current entry requirements for vaccinated and unvaccinated travelers to Thailand?

Travelers to Thailand currently face different entry requirements based on their vaccination status. Vaccinated visitors no longer need to take a PCR test and simply need to present proof of vaccination upon arrival. In contrast, unvaccinated travelers are required to show either a PCR test or an ATK certified test taken within 72 hours before their flight. A recent traveler reported that upon arrival, they were not asked for their vaccination card or PCR test, indicating a possible easing of entry protocols.
