Is yellow vax book required for UK travel?

[Polar Bear]

Depending on how things pan out next month, I might go back to the UK for a couple of weeks. If I do, I'll renew my passport while I'm there. Is the yellow vaccination book required for UK travel? Or can I just use my vaccination certificate? (I had 2 x Az.) If it's not needed, I'd rather wait and get the yellow vax book issued with my new passport number, but obviously, that won't be possible if I need it to travel back.

According gov.uk a vaccination certificate is OK for travel from Thailand.  It needs to meet the following;

 

If you use a vaccine certificate as proof, it must be issued by a national or state-level public health authority, be in English, French or Spanish, and include as a minimum:

• your forename and surname(s)
• your date of birth
• vaccine brand and manufacturer
• date of vaccination for every dose
• country or territory of vaccination and/or certificate issuer

The certificate has all of that, so it should be fine. Thank you!

So not a letter from a hospital?
