There appears to be three methods of providing proof:- Certificate, Mor Prom App and Vaccination Booklet (yellow book).
To me it appears that none of these are 100% stand alone. Let me explain! I and some friends had our vax at Bang Sue, 2 jabs, and received a certificate at the end of the procedure but.... we can get no information out of the QR code when we scan it. I believe those who were jabbed at the 2 hospitals are able to scan their QR codes, so it seems that just the station is causing the problem. Next.. we cannot enter the Mor Prom app itself but we can get into it via Line ......but, our passport country is given as Thailand and there seems to be no way of changing that! Thirdly, the Yellow Booklet has all the information correct but it has no QR code.
I am sure that some intelligent person will be able to provide some solutions to my problems.
1. Can anyone who was vaccinated at the station scan their QR code?
2. Does anyone know how to change the passport country to the correct one on the Line version of the App?
I look forward to being educated! Probably by a 5 year old!
