Do I need to answer questions about yellow fever vaccination if I'm traveling from the UK to Thailand?

Thailand Visa Rules TDAC Form Yellow Fever Vaccination Immigration Requirements Travel from the UK Expat Guidance

ORIGINAL POSTER

I've noticed on the new TDAC form that starts on the 1st May 2025 there is a question asking about 'yellow fever' vaccination certificate.

There is an asterisk sign (*) which means that question MUST be answered.

What I need to know is: if you answer 'NO' meaning you don't have a yellow fever vaccination does the next question go away?! 

The next question is the date of the vaccination, which also has an asterisk (*)

I'm guessing we won't know until this procedure starts on May 1st. 

My question relates if travelling from the UK England

TLDR : Answer Summary

The discussion revolves around the new TDAC form effective from May 1, 2025, which includes a mandatory question regarding yellow fever vaccination. Users clarify that this requirement only applies to travelers who have been in high-risk countries for yellow fever within the last two weeks. If traveling from the UK without recent travel to these countries, the question may not be relevant, and one can select 'NO' in response to the vaccination question.

That yellow fever vaccination option only appear when you travel from some high risk country. If you are from UK and have no recent travel history to those countries(eg. africa), that option will not appear and you don't need to answer that question.

Not changed if you are coming from a country by Thai goverment list (yellow fever zones) there is a desk you go to before immigration to show your yellow fever certification. Will see how it works now when i come from Congo early may

It only applies to travelers from high risk countries, and you can just say No.
