How can children from the U.K. aged 12-16 obtain a Thai Pass when only one vaccination is required?

In Thailand, each traveler over the age of 12 must present a Thai Pass. However, children aged 12-16 from the U.K. may only need to show proof of one vaccination. To obtain a Thai Pass, it is necessary to ensure that the vaccination policy is in line with Thai regulations. Recently, Thailand has recognized that if a country considers one dose sufficient for full vaccination, then it is accepted in Thailand as well.
