If you are travelling out of Thailand you need to closely check the Covid entry requirements of the country. I'm not sure about Dubai but I hope to travel to Oman in October and their regulations clearly state that the Covid vaccination certificate must have a QR code that can be scanned and links to a database that confirms the validity of your vaccination. The vaccination certificate issued by Thailand's MoPH, as seen in your Mor Phrom record, does this and should be officially recognized. The Thailand Vaccination Passport does not have a QR and is really not much use anywhere right now. It looks good but that's about all. On the other side of the coin, I have two mates who are also hoping to travel to Oman at the same time. One is from the US and the other Canadian and neither has a vaccination certificate with a QR code. Both are having issues getting visas.
