What does a "Vaccination Certification" look like? I have dose 1 on my Mor Prom app, and after dose 2, I will get a digital certificate, (which if necessary, I could print out). Is that it?
Also, my understanding is that the COE is for ENTRY into Thailand. I'm wondering about EXIT from Thailand. What do you have to show to the airline check-in for proof of vaccination? Would it be the Mor Prom digital/hard copy certificate? What have travellers exiting Thailand had to show? (I'm assuming if what you show is accepted at check-in here, and you board the flight, you are not going to have an issue at your destination, upon arrival.)
