Would you trust your life or heath to Thais? Fake vaccine? Expired vaccine? Wrongly stored vaccine? How about complications after vaccine? What are the Thai documents worth, if get, to prove vaccination? How will it be received when Thai population is not fully vaccinated but the dirty farangs get it for free...
Why should vaccination help tourism when after receiving vaccination you can feel sick and have fever for some days, would you do that in yoir holidays in a corrupt and unsafe place like Thailand, not if you come from a better place like central Europe...
How will they sell it to yhe unvaccinated Thais?'The dirty farangs need to be vaccinated because they make us sick??'
