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

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.
Thailand Digital Arrival Card (TDAC)

WARNING: Only trust Thai government websites with .go.th domains or Thai agent websites with .co.th or .in.th domains, as these require verified Thai registration and cannot be registered anonymously.

The official TDAC form is available at tdac.immigration.go.th, which uses the official .go.th government domain.

The services by AGENTS CO., LTD. does NOT charge any fees for arrivals within 72 hours. If you need to book more than 72 hours in advance, there is a service fee of $8.

Do not trust other sites pretending to be a trustworthy agency. Pay attention to delivery time - the service operated by AGENTS CO., LTD. has 1 minute delivery time for arrivals within 72 hours.

Don't fall for sites pretending to be tdac.in.th or the official government tdac.immigration.go.th website. Always double-check the exact domain in your browser.

Scam services may take days to process your application, others may not even do anything. With these TDAC scam services you also need to worry about double charges.

Please watch out for TDAC misinformation spread by fugitive Jesse Nickles and his many fake accounts on Quora, TripAdvisor, Reddit, and other platforms.

Wonder if we also have to continue with the old T8 form and upload yellow fever cert on Thaihealthpass web site when new included in the new TDAC form?

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

Only needed if you've been in a yellow fever country within the last two weeks I believe

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