To answer straight, no I did not. I have copied and pasted what the DEFRA site says about this and below that I have explained what my vet told me when I asked him about the booster.
Defra says:
[
b]Record of vaccinationEnter the following details in section IV of the animal’s passport or official third country veterinary certificate if the animal is being prepared in a non-EU listed country, and vaccination record:
its date of birth/age
the microchip number, date of insertion and its location in the animal
date of vaccination
the vaccine manufacturer, product name and batch number
the date by which the booster vaccination must be given (the “Valid until” date) (calculated by reference to the vaccine manufacturer’s data sheet[/i]
Revaccination (boosters)
After an animal has been vaccinated, it must be given booster vaccinations to remain qualified for PETS (but it doesn't say when, does it? my words here). This must be done by the “Valid until” date on the animal’s EU pet passport, third country veterinary certificate or PETS certificate and recorded in section IV of the passport and on the animal’s vaccination record. The revaccination
interval for cats] (again my emphasis) may be different to that for dogs (refer to the vaccine manufacturer’s data sheet). Read the microchip before revaccination.
If the booster date is missed, the animal will have to be vaccinated and blood tested again. The details in section V of the passport headed “In case of a further test” must then be completed – in Great Britain by an LVI. The animal will have to wait 6 calendar months from the date a blood sample was taken that gave satisfactory result following revaccination before it may enter the UK under PETS.
The next step is either a blood test or, for a pet not returning to the UK, or whose owner wants the blood sample to be taken in another listed country, issue a passport. Note that a blood test is required for PETS to enter Malta and, from countries other than the UK, the Republic of Ireland.

My vet said that most people in the states give their pets the yearly vaccination but because we were giving them the 3 year vaccine that would mean they would need their booster (on the Pet Travel Scheme document it refers to the Valid Until date) right before that valid until date was up. If you will look back up under the section that says "Record of Vaccination" it says the
date by which the booster vaccination must be given (the “Valid until” date) (calculated by reference to the vaccine manufacturer’s data sheet).
Here is my situation.
Cats vaccinated for 3 years on May 7th, 2003 (Valid until date is May 7th, 2006)
Wait 30 days do blood draw on June 9th, 2003
6 months from this date they can leave provided they have all clear (they did).
If I waited longer than this it would have been ok because I had until the "valid until date". Meaning I had until May 7th, 2006) It doesn't say how long after you have and you can't go because it's valid until the valid until date! lol
But I will say I am not 100% on this. This was according my vet almost 3 years ago. Unless some thing has changed since then. My question for you is, does your vet not have the answer to this? My vet was ever so helpful and always called me back once he found out. I would be glad to pass along my vets number if you want to ring him. He wouldn't care!!
