Do I only need the Thailand Pass to travel after my vaccination certificate is approved?

Once your vaccination certificate is uploaded and your Thailand Pass is approved, the Thailand Pass is a crucial document for travel. However, it is advised to have printed copies of your vaccination certificate, insurance, and Thailand Pass, as these will all be checked at the airport. There are recommendations to obtain an international vaccination certificate in English, as there may be concerns regarding the Spanish version at Bangkok Airport. You may also need to present additional documents such as your boarding pass, visa, and a filled-out TM6 landing card at immigration.
