If I got my covid vaccination in Thailand last summer, which had a qr code, will my Thailand pass application be automatically approved?

That is not a official website so it may be incorrect info. I have not seen anything like that on the any official site.

They should certainly accept the QR code done by the Ministry Of Public Health. 

i would think that u would not be vax till third shot

At this time you are considered be fully vaccinated after two shots. To enter Thailand the 2nd one has be done at least two weeks.

It will be some time before they will require a booster shot to be fully vaccinated.

Expats who are pfizer vax in thailand aren’t eligible for a Thai gov booster  unless they go Moderna route…

 

so fully vax = 2 doses 

Based on my experience, your Thai Vaccine QR Code uploaded doesn't guarantee you an automatic approval for the pass.

 

I had both of my vaccines at Bumrungrad and was issued a Thai Certificate with QR Code. I uploaded the certificate and QR Code for vaccine one and two and It then took a week for my Thailand  pass to be manually approved.

I had 2 x AstraZ in Thailand, and it took 7 days for my Test & Go Thai Pass to be approved.
